How are histone modification enzymes (such as HATs) and chromatin remodeling complexes recruited to unmodified chromatin, and ho
kiruha [24]

Answer:

A histone modification mechanism proliferate through a process that includes post translational modification procedure. The methylation, acetylation as well as ubiquitylation are one of the main modifiers that help in activation of silent genes and ultimately these covalently bonded histone modifiers help in regulating chromatin. The PTM has a main role in altering histone structure by these modifier's recruitment....

Somatic cells of roundworms have four individual chromosomes per cell. How many chromosomes would you expect to find in an ovum
andrezito [222]

Answer:

2 chromosomes

Explanation:

The cell of an eukaryotic organism like roundworm contains the Nucleus, which harbors the genetic material embedded in the chromosome. The number of chromosomes of that organism is contained in each cell.

Somatic cells, also called body cells, are all other cells asides sperm and eggs, that form the tissues and organs of an organism. Somatic cells are usually diploid i.e two sets of chromosomes from each parent. In this question, the roundworm has 4 chromosomes in its somatic cell.

The reproductive cells or sex cells (sperm and eggs) of an organism always result from meiotic division of specialized cells.

Since meiosis is a kind of division that results in cells with their chromosome number reduced by half (haploid), it therefore means that the ovum and sperm cell will be expected to contain 2 chromosomes each.

This way, when fertilization occurs (sperm and egg fusion), the resulting zygote, which will eventually develop into an adult organism, will have 4 chromosomes.

Which of the following lists, in correct order, the phases of interphase? View Available Hint(s) G1, A) prophase, and S Prophase
Lady_Fox [76]

Answer:

G1 - S - G2 (may be is option D)

Explanation:

The interface begins with phase G1 where the cell increases its volume and the mass is doubled.

Then, we continue with the S phase where DNA and histones are synthesized.

Afterwardsy we reach the G2 phase where the chromosomes are duplicated.

Finally we reach, the begining of mitosis.
