Which of the following is an example of genomic imprinting in humans? Which of the following is an example of genomic imprinting in humans? A random pattern of autosomal allele inactivation is observed. In some allele pairs, only the paternal sourced allele is expressed, and in others, only the maternal sourced allele is expressed. The maternal and paternal alleles of a gene pair are both expressed. Human males have only one Y-chromosome and one X-chromosome. One of the two X-chromosomes in females is randomly expressed and the other is repressed.

Answers

Answer:

In some allele pairs, only the paternal sourced allele is expressed, and in others, only the maternal sourced allele is expressed.

Explanation:

Genomic imprinting is an epigenetic phenomenon where alleles are differentially expressed depending on their parental origin (for example, paternally expressed when it is inherited from the father). Genomic imprinting is controlled by epigenetic modifications (for example, DNA methylation, histone acetylation, etc) which works together to preferentially activate the expression of the allele inherited from one parent and simultaneously silence or “​imprint” the expression of the allele inherited from the other parent. In humans, an example of genomic imprinting is the case of the insulin-like growth factor 2 (Igf2) gene, which is maternally imprinted (repressed), thereby this gene is only expressed from the paternal allele.

is not sleeping bad for u
hi I didnt sleep for 16 hours and I have messed up sleep pattern
will i commit no alive

Answers

No many people stay awake for 16 hours or more the only time you should be concerned is if you younger than the age of 13 try to sleep if you can try to get atleast 4 hours if any at all

Answer:

It depends. 16 hours is a long time not to sleep. You need to sleep though. Your body needs at least 8 hours of sleep. But you need at least 5 to 6 hours of sleep. So your body can regenerate itself.

g It was noted in the Experimental Pathways feature in Section 10.4 that at least two- thirds of the human genome is derived from transposable elements. The actual number could be much higher, but it is impossible to make a determination about the origin of many other sequences. Why do you suppose it is difficult to make assignments about the origin of many of the sequences in the human genome

Answers

Answer:

TEs are repetitive and mobile elements, thereby it is hard to trace their origins  

Explanation:

Repetitive elements are patterns of nucleotide sequences in the DNA characterized to have multiple copies throughout the genome. DNA mini-satellite and Transposable Elements (TEs) are some examples of highly repetitive DNA. TEs are repetitive mobile elements that have the ability to jump within the genome and occupy a major part of eukaryotic genomes. For instance, there is a type of TEs called retrotransposons which mobilize through a copy-and-paste mechanism, thus increasing their number in a genome. In consequence, TEs represent highly repetitive and dynamic genomic sequences, and thereby it is hard to trace their evolutionary histories.

Answer:

Could it be the higher installation costs than fossil fuel plants????

Explanation:

An estuary collects sediments from the ocean and rivers that feed into it. The sediments swirl around and then settle to form a mudflat. Eel grass is then established on the mudflat. The ecosystem changes over time and ultimately develops into a salt marsh that contains mangrove trees.
Which of the following is likely NOT involved in this example of ecological succession?

A)
The rotting remains of plants add to the fertility of the soil.


B)
The soil becomes so fertile that eel grass is replaced by other plant species.


C)
The roots from plants help stabilize the sediment, keeping it in place.


D)
The concentration of salt becomes so high that all plant life is destroyed.

What is a farm plot?

This is an area of land that is used for agricultural purposes. A farm plot usually has one or more crops planted on the soil.

The farmers has to water the crops daily to ensure that the crops grow well. He also has to weed to reduce competition for the crops.

Using fertilizers helps to improve the yields and pesticides drives unwanted insects from the crops.

The TAS2R38 gene encodes a receptor protein that influences the ability to taste bitterness. The gene has two alleles: a dominant, wild-type allele that enables an individual (taster) to taste bitterness and a recessive, mutant allele that interferes with the ability of an individual (nontaster) to taste bitterness. In a sample of 2,400 people, 1,482 were found to have the dominant (taster) phenotype. Assuming that the population is in Hardy-Weinberg equilibrium, approximately how many individuals in the sample are expected to be heterozygous for TAS2R38

Answers

Answer:

The correct answer is - 1133.

Explanation:

According to H-W equilibrium;

p2 +2pq + q2 = 1 ........... eq.1   and

(p+q)2 = 1 ..............eq.2

Here q = frequency of the recessive allele,

and p = frequency of the dominant allele in the population

The genotype of p2 + 2pq shows the dominant(taster) phenotype.

The genotype of q2 shows the recessive(non-taster) phenotype.

q^2 = (2400 - 1482)/2400

= 0.3825  

= 0.618

using eq. 2 we get p= 1-q

=0.382

2pq = No. of heterozygotes/2400

No. of heterozygotes = 1133.1648

Describe what happens to DNA during the S stage of interphase.

Answers

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

5. What does EGS stand for in geothermal energy?
A) Engraved Geothermal System
B) Enhanced Geothermal System
C) Exhaust Gas System
D) Engineered Geophysical System​

Answers

(EGS) stands Enhanced Geothermal Systems which can greatly increase geothermal energy utilization. Therefore, option (B) is correct.

What is EGS?

Enhanced Geothermal Systems (EGS), which are also referred to as engineered geothermal systems on occasion, present a significant opportunity for significantly broadening the application of geothermal energy.

In an EGS, fluid is injected into the subsurface under conditions that are carefully regulated. This causes previously closed cracks to reopen, which in turn creates permeability in the rock. The increased permeability of the rock makes it possible for fluid to move freely within the newly fractured rock and for heat to be transported to the surface, where it can be used to create electricity.

The stages of mitosis were originally defined by cellular features observable through a light microscope.

a. True
b. False

Answers

Answer: TRUE

Explanation:

The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:

--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.

--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.

--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.

--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.
