Question

If a cell at metaphase of mitosis contains 20 sister chromatids, how many chromosomes will be present in a g1 cell

Answer 1

The correct answer is 10 chromosome. Mitosis is the type of cell division that takes place in the somatic cells or the body cells where the parent cells divides into two daughter cells with the same genetic composition as the parent. Therefore, the number of chromosomes in the daughter cells remains the same as that of the mother cells. The opposite is the meiosis, which involves division of a germ line cells into four daughter cells which contains half the number of chromosomes as the parent.

Answer 2

Answer:

20 chromosomes

Explanation:

The G1 phase of the mitosis is the phase where a cell grows and prepares itself for cell division , by this time the cell has yet even initiated to divide. In the G1 phase the cell synthesizes enzymes and nutrients that will be needed in the later stage of mitosis for DNA replication and cell division. After the G1 phase DNA of the cycle starts replicating during the S phase. Thus the number of chromosome remains the same during the G1 phase of mitosis cell division.
