Nostrana [21]

Answer: The DNA on the paternal copy of the chromosome will be methylated at the imprinting center, while the DNA on the maternal copy of the chromosome will not be methylated in this region.

Explanation:

Chromosomes are DNA structures associated with proteins such as histones. They are found in the nucleus of cells and contain genetic information for the development and functioning of an organism. Human beings are diploid, meaning that they possess two copies of each of the 23 chromosomes (a total of 46).

Gametes, which are sex cells such as the sperm (produced by the male) and the egg (produced by the female) that are haploid. This means that they possess only one chromosome of each pair. During fertilization, a male gamete fuses with a female gamete to generate a zygote, which will give rise to a new human being. <u>This new individual will possess half of the genetic material from its father and half from its mother. Thus having a total of 46 chromosomes, 23 from each parent</u>.

Genetic imprinting modulates gene expression by chemical modification of DNA and/or modification of chromatin structure. Often, genetic imprinting causes a gene to be expressed only on the chromosome inherited from one of the parents. One example of imprinting is DNA methylation, which is a process by which methyl groups are added to DNA. <u>Methylation modifies DNA function when found in the promoter gene, repressing gene transcription. This means that a methylated gene will not be expressed</u>, that is, it will not produce a protein encoded by that gene. So, if a region of DNA is imprinted in the sperm cell, the paternal chromosome inherited from this sperm will be methylated in the genes of the offspring. And the offspring will only express the maternal copy inherited, which will not be methylated.

During which part of the cell cycle are cells not reproducing ?
dem82 [27]

Answer:

Interphase is the portion of the cell cycle that is not accompanied by gross changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A cell in interphase is not simply quiescent.

Which of the following is true of environmental​ sustainability?
kompoz [17]

Answer:

Answer is C. Companies are learning that engaging in sustainable practices is good for business.

Explanation:

Environmental sustainability is the way of reducing the amount of toxins in the environment.  This act include renewing the waste products such as plastics and nylon in the environment. The deterioration of these waste products is dangerous to the environment.

This act can be achieved when good policies are made on proper waste disposal and renewing the renewable substances.

Example is invention of wind power which prevent global warming.

In this case, companies should understand that engaging sustainable practices will reduce things that may affect their productivity, and what that can pollute their products and render it useless.
