Given the following sequence of DNA, write the correct sequence of complementary DNA bases.
TACCGATAA
Given the following sequence of DNA, write the correct sequence of complementary mRNA.
ACCGTACTG
Given the following sequence of DNA write the correct sequence of amino acids.
ATAGGCGTA
Answer:
1. ATGGCTATT
2. UGGCAUGAC
3. mRNA: UAU-CCG-CAU, amino acids: tyrosine(tyr)-proline(pro)-histidine(his)
Explanation:
For DNA, the complementary bases are T=A and C=G. This means every time you see one of these letters, the corresponding letter goes with it. For mRNA, the bases are T=A, A=U, C=G. It is the same except now, there should be no "T" in the mRNA sequence. With amino acids, you would first code for the mRNA sequence, every three letters being the amino acid sequence. To find the amino acid, you would look at a codon chart unless your teacher wants you to memorize them. The first three letters of the amino acid are the abbreviation.
If an animal has 21 chromosomes before replication, how many do they have after?
Answer:
Animals usually have 22 pairs of homolog chromosomes (autosomes) and as sex chromosomes 2 x chromosomes (in female), or 1 x and 1 y chromosome (in males), thus in total 46 chromosomes per body cell (see human karyogram; 2n = 46) and 92 chromatids per cell after replication.

In people-eaters, purple is dominant to white. A true-breeding white mutant is mated with a different true-breeding white mutant. All of the F1 are purple. When the purple F1 offspring mate with each other, their offspring occur in the ratio of 9 purple : 7 white. Which phenomenon explains the purple F1 offspring
Answer:
The correct answer is - Complementation.
Explanation:
In this pattern of inheritance, there are two same type mutants that are crossed that are true-breeding white with another true-breeding white mutant. Let these mutants are CCpp and the other be ccPP.
All the f1 offspring produced are found to be purple in color as offspring will be CcPp. The products of both gene C and P required for the purple pigment to be expressed these genes complement each other and the absence of any of gene results in lack of the dominant phenotype.

Each fragment generated during the cycle sequence reaction is labeled with:
A. All four colors of fluorescent dye throughout the length of the fragment
B. All four colors of fluorescent dyes at one end of the fragment
C. One color of fluorescent dye at one end of the fragment
D. One color of fluorescent dye throughout the length of the fragment
Answer:
C
Explanation:
In cycle sequencing technique, four distinctive fluorescently named dideoxyNTPs are utilized ( ddATP, ddGTP, ddCTP and ddTTP) notwithstanding ordinary dNTPs. each ddNTP marked with an alternate fluorescent color. Toward the finish of the experiment, the outcome yields various pieces of variable lengths each resulting in a solitary terminal fluorescent ddNTP towards the end.

B. Penguins with higher body fat tend to survive nesting in the Antarctic winter, while leaner penguins often die.
C. A gene for disease resistance in fir trees is transferred to pine trees using modern DNA technology, allowing farmers to maximize pine tree growth.
D. Because big game hunters sought elephants for ivory, often poaching those with the biggest tusks, more African elephants today naturally lack tusks compared to the elephant populations 100 years ago.
E. In subsaharan Africa, genetically modified grass varieties that carry genes for disease and drought resistance are now available to farmers, providing more sustainable food sources for their livestock.
A set of 23 chromosomes in a human cell
contains 3.2 billion pairs of DNA bases in
sequence. On average, about how many pairs
of bases are in each chromosome?
Explanation:
The human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells. Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins.The human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells.

What is chromosome ?
A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

9. Which nucleus has role in conjugation in Paramecium
a) Mega nucleus
b) Micronucleus
c) Macronucleus
d) Cellular nucleus
( b ) Micronucleus has role in conjugation in paramecium.
The organism's germ line genetic material is kept in the micronucleus. It is in charge of the genetic rearrangement that takes place during conjugation and generates the macronucleus (cross-fertilization). Thus option B is correct.
What Micronucleus role in conjugation in Paramecium?The pairing and subsequent fusion of two paramecia is a process known as conjugation. It is known as a cytoplasmic bridge where they converge. After meiosis, the diploid micronucleus divides into four new micronuclei. The micronuclei of the cell, all except one, break down.
This method doesn't include meiosis or nuclear fusion. It manifests in a single person in the manner described below: Macronucleus deteriorates and vanishes. Eight nuclei are produced after the two micronuclei divide twice through mitosis.
Therefore, Micronucleus has a role in conjugation in Paramecium.

A woman and her baby are on a TV talk show to determine whether or not a particular man is the father of the child. Mom is blood type O and the baby is blood type B. The potential dad is blood type A. Is it true or false that he is the father?
Answer:
No that is not the father
Explanation:
The fathers blood would have to be type B. Type A is dominate to O and co-dominate to B so you get AB blood, type B blood is dominate to O blood. So if the mom has to be OO to show O blood and the father has to be AA blood because he isn't AB or AO, which could make the baby AO or OO blood. Since none of this is true the "TRUE" father would have to have AB, BB, or Bo blood.

d) During Transcription, a nucleotide has been deleted. Explain the effect this will have
on DNA as well as what happens in each step along the way to a protein.
Answer:
this mutation may change the open reading frame of the resulting RNA sequence and its final product, which is a protein in the case that this gene is used to synthesize a messenger RNA (mRNA) sequence
Explanation:
During the transcription, a region of DNA named 'gene' is used as template to produce an RNA molecule, typically a primary transcript of mRNA (pre-mRNA). Subsequently, this pre-mRNA suffers a process named RNA processing in order to generate a mature mRNA which is finally used to create a protein by a process called translation. If a deletion occurs during transcription, it may change the open reading frame (ORF) of the resulting mRNA when the mutation occurs in an exon of the protein-coding gene (i.e., occurs a frameshift mutation), while this deletion may not have any effect if it is localized within the introns which are removed during RNA processing. A frameshift mutation will change the amino acids that are added to the nascent polypeptide chain during translation.
* Apply Concepts A particular plants diploid number of chromosomes is 50. Describe the number of chromosomes in one of the plant's cells during its sporophyte phase and during its gametophyte phase,
Chromosomes have hereditary function that are capable of self-duplication and they have thread-like structures seen inside the nucleus of plant and animal. In plants, they go through a cycle called alteration of generation that has multicellular stages. One is sporophyte that is a diploid, and the other is gametophyte with a haploid.
Moreover, spores are produce through meiosis so it go through a process of chromosome reduction in order to create a haploid spores. While, gametes undergo mitosis and the structure is already a haploid, which means that the number of chromosomes will not change in order to produce haploid. In this case, the plant have both spores and gametes and the similarities is that, they are both singles celled and a haploid. Therefore, the number of the chromosome in the gametophyte generation is also 32.
