<span>For a cell with nucleus to divide successfully, it needs to prepare for cell division by growing, accumulating nutrients needed for mitosis and duplicating its DNA. The duplicated DNA will eventually be distributed between the two new cells formed. The correct option is A.</span>

What are viable explanations for the consistent observation of a few black mice on the island?
PolarNik [594]

They undergone genetic mutation that influenced their fur color.

Mutations result either from accidents during the normal chemical transactions of DNA, often during replication, or from exposure to high-energy electromagnetic radiation (e.g., ultraviolet light or X-rays) or particle radiation or to highly reactive chemicals in the environment. Mutation can be of 4 types Germline mutations occur in gametes. Somatic mutations occur in other body cells. Chromosomal alterations are mutations that change chromosome structure. Point mutations change a single nucleotide. Frameshift mutations are additions or deletions of nucleotides that cause a shift in the reading frame. Factor that influenced  mutation are the size of the gene, its base composition, its position in the genome, and whether or not it is being actively transcribed influence its mutation rate.

Cell Division Homework #1 Introduction to Cell Division Directions: Compare and contrast the following pairs of terms:
wel

Answer:

Sister chromatids / centromeres: When a single chromosome has been replicated in copies, each copy is called a sister chromatids.

A special part of the chromosome called the centromere holds the two sister chromatids together. A centromere is like a built-in rubber band for two sister chromosomes.

Mother cell / daughter cell: identical.

Daughter cells are genetically identical to the mother cell at the stage of production through mitosis.

On the other hand, at the stage of production through meiosis, the daughter cells are genetically different and contain only half of the genetic material of the mother cell.

Interphase / cell division: A cell spends most of its time in what is called interphase, and during this time it grows,

replicates its chromosomes, and prepare for cell division.

The cell then leaves Interphase, undergoes mitosis, and completes its division.

DNA / chromosome: Genes are segments of deoxyirbonucleic acid (DNA) that contain the code for specific protein that functions in one or more types of cell in the body

Chromosomes are structures within cells that contains a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Mitosis / cytokinesis: Basically, mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature.

Cytokinesis is the process where the cytoplasm of the cell divides to form two 'daughter' cells. The result is the formation of two 'daughter cells', each having a nucleus.
