Among 1,000 gametes produced by a plant of genotype o ci +/+ + p, what types of gametes would be expected, and what number would be expected of each? Assume that the chromosome interference across this region is 80%.
Answer:
Expected gametes : o+ ci+ p+,o- ci- pi-, o+ci- pi+,o- ci+ pi-, o+ci+ pi-, o- ci- pi+
Explanation:
Genetic distance between genes is equal to the recombination frequency, so the total number of recombinant gametes can find out by multiplying the recombination frequency of both sides to the total number of gametes.
Interference= .80;
Coefficient of incidence
= 1 - 0.80
= 0.20
15cM = 15% recombination,
20cM = 20% recombination.
Then, Number of recombinant offspring
= 15 x1000/100
= 150,
Gametes expected= o+ ci+ p+,o- ci- pi-, o+ci- pi+,o- ci+ pi-, o+ci+ pi-, o- ci- pi+
QUESTION 20 "Nitrous acid causes all possible transitions (A<-- -->G, C<-- -->T). If a protein has an alanine at position 65, what amino acid(s) would be likely to replace alanine as a result of nitrous acid mutagenesis
Answer:
Explanation:
Nitrous acid mutation occurs when a Nitrogenous base is replaced by a keto group.
Alanine is replaced by hypoxanthine,
Cytocine is replaced b Uracil
Guanine is replaced by Xanthine.
Nitrous mutation often affects Adenine, Cytocine and guanine. The Nitrogenous base is changed into another substance(keto group)
Alanine at position 65 would be replace by hypoxanthine a keto group which is a form of nitrous mutation.
Other forms of amino acid mutation
Mutation of amino acid nitrogenous base can either be transition or transversion.
Transition is the substitution of a purine base by another purine base. Since purine are Adenine and Guanine
Pyrimidine is cytocine and thymine or Uracil. Adenine can be substituted for by guanine or guanine by adenine
E.G A - G now G - A where Guanine substitute Adenine
Whole transversional substitution can also occur which involve a purine been substitued for by a pyrimidine or pyrimidine by a Purine.
A - G
Now C-G where cytosine substitute Adenine.
Rafael models a longitudinal wave using a coiled-spring toy. If he wants to model a longitudinal wave that carries more
energy, how should he move the end of the spring?
:::
O side to side, using larger motions
O side to side, using smaller motions
O forward and back along the spring, using larger motions
O forward and back along the spring, using smaller motions
Answer:
O forward and back along the spring, using larger motions
Explanation:
Longitudinal wave that carries more energy, he move the end of the spring by pushing the spring forward and backward directions using larger motion that creates two regions in the spring, the crowded area known as compression and more distance between parts of the spring known as rarefaction. If there is more compression in the spring so there is a lot energy present in the spring. So it is only possible when using larger motions in the spring.

What kind(s) of cells can develop from totipotent stem cells?
O A. Only cells that are identical to the original stem cell
B. Only cells that are closely related to the original stem cell
C. Any cells of the human body, but not cells of the placenta
D. Any cells of the human body or the placenta
Answer:
D.
Explanation:
Totipotent cells can make any of the 220 cell types in an embryo, as well as the cells found in a placenta!
Any cells of the human body or the placenta can develop from totipotent stem cells. Therefore, the correct option is D.
Totipotent stem cells have the unusual ability to differentiate into any type of human body cell, including placental cells. They have the ability to generate all types of cells, including endoderm, mesoderm, and ectoderm, the three basic germ layers. Because of their potential for development, totipotent stem cells can produce both extra-embryonic and embryonic tissues. Although cells produced from totipotent stem cells can differentiate into any cell type, due to maturation and specialization processes, they are not always identical to the original stem cell.
Therefore, the correct option is D.

In which would you be most likely to find plants and animals that are adapted to survive in extremely cold temperatures
This question is incomplete because part of the content is missing; here is the complete question:
In which biome would you be most likely to find plants and animals that are
adapted to survive in extremely cold temperatures?
A. Desert
B. Savanna
C. Rain forest
D. Tundra
The correct answer is D. Tundra
Explanation:
Tundra biome is one of the coldest biomes on Earth, indeed, the temperature in this biome can be as low -50° C in some zone. At this extremely cold temperature, animals and plants have adaptations to survive in these climatic conditions. For example, animals such as the arctic hare or the polar bear that are found mainly in the tundra biome have thick fur that helps them keep body temperature despite low temperatures in their environment. Thus, the biome in which you would most likely find species adapted to extremely cold temperatures is the Tundra.

The frequency of purple pollen cones is 0.34 in a population of Virginia pine (Pinus virginiana). In the same population, the frequency of four needles per fascicle is 0.67.
If these two traits are independent, what is the probability that a single pine tree has both purple pollen cones and four needles per fascicle? (calculate to 2 decimals)
Answer: P(p and f) = 0.23
Explanation: The frequency of a specific trait is also the probability of that trait appearing in that population. So:
Probability of purple pollen cones: P(p) = 0.34
Probability of four needles per fascicle: P(f) = 0.67
Using multiplication rule:
P(p and f) = P(p)*P(f)
P(p and f) = 0.34*0.67
P(p and f) = 0.23
The probability of having both purple and four needles is 0.23

Consider that it takes, on average, 24 hours (or 1,440 minutes) for each onion root tip cell to complete the cell cycle. You can calculate the amount of time spent in each phase of the cell cycle form the percentage of cells in that stage.
Percentage of cells in stage X 1,440 minutes = ________ minutes of cell cycle spent in stage.
Answer: Hope this helps you :)
To calculate the time spent on each stage of the cell cycle, we need to know the total time required to complete the cycle and the percentage of cells that are in that stage. Then, take the product of both values.
--------------------
According to the statement,
The percentage of cells in a stage X 1,440 minutes = Time in minutes of cell cycle spent in the stage.
So, to know how much time is spent in each stage of the cell cycle, we need to know the time it takes for a cell to complete the whole cell cycle, and how many cells there are.
We already know that it takes, on average, 24 hours (or 1,440 minutes) for each onion root tip cell to complete the cell cycle.
Now, we should count the number of cells. Since I do not have a slide, I will assume that there are at least 50 cells, and from that 50 cells present in the slide, 25 are in the same stage. Let us say that the 25 cells are in the prophase.
So, considering a total number of 50 cells (100%), 25 cells equals 50% of the total.
Now, we know that
Time required to complete the cell cycle = 1440 minutesPercentage of cells in the prophase = 50%
Minutes spent in prophase = % of cells in prophase x 1440 minutes
Minutes spent in prophase = 50% x 1440 minutes
Minutes spent in prophase = 0.5 x 1440 minutes
Minutes spent in prophase = 720 minutes
According to this example, cells spend 720 minutes of their time in the prophase.
Now, I suggest you count how many cells do you have in your slide, and recognize how many are in each of the stages. Then you will be able to calculate the real-time spent per stage.

After duplication, at what point does a cell become two cells with identical DNA? starting in prophase end of anaphase end of cytokinesis
Answer:
The correct answer is - end of cytokinesis.
Explanation:
Cytokinesis :- a procedure that partitions the cytoplasm and plasma layer of a cell, bringing about two indistinguishable cells that contain their own DNA, nucleus, nuclear membrane, and plasma membrane.
During the last phase of the cell cycle, cytokinesis permits the cell to complete the process of isolating, making two cells with indistinguishable duplicates of DNA
The cell squeezes in the equator area with the assistance of a ring of contractile protein filaments. The formed cleavage furrow develops until the two cells squeeze off totally.
Thus, the correct answer is - end of cytokinesis.

a. Yeast cells grow faster than bacterial cells when expressing human proteins.
b. Yeast cells splice mRNA in an identical manner as human cells.
c. Yeast cells fold and modify proteins in a manner similar to human cells.
d. Yeast cells use the same genetic code for specifying amino acids as human cells.
Answer:
The correct answer is c.Yeast cells fold and modify proteins in a manner similar to human cells.
Explanation:
Yeasts are known as one of the most useful microorganisms to humans due to the best known eukaryotic microorganisms.
As yeasts are eukaryotes like humans and hence have the system for post translational modification that is needed for proper folding of eukaryotic genes. Due to this fact and advantages yeast is considered by many to be the superior type of organism to use for for producing proteins.
Thus, the correct answer is C. Yeast cells fold and modify proteins in a manner similar to human cells.
A rat population has an average weight gain between weeks 2 and 4 of 10 grams, and the narrow-sense heritability of the weight gain between 2 and 4 weeks is 25%. What average weight gain would be expected among the offspring of parents whose average gain was 15 grams?
Answer:
The correct answer is - 11.25
Explanation:
Given:
Average weight gain between weeks 2 and 4 = 10 grams
The narrow-sense heritability of the weight gain between 2 and 4 weeks
= 25%
Then
Average weight gain would be expected among the offspring of parents whose average gain was 15 grams-
by the formula:
Average weight gain between weeks + (h) (Average weight gain between weeks - parents average gain )
= 10 + 0.25 (15-10)
= 10 + 0.25 (5)
= 10 + 1.25
= 11.25
Thus, the correct answer is - 11.25

Which of the following is a correct comparison between RNA polymerase holoenzyme that functions in transcription and the primase enzyme that functions in DNA replication?
A) Both enzymes synthesize RNA
B) Both enzymes are bound by sigma factor
C) Both enzymes shnthesize DNA
D) Both enzymes are composed of RNA
Answer:
Option A
Explanation:
RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it.
And since primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
