Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its …
How many chromosomes do human daughter cells have?
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2.
What can happen if cells do not duplicate correctly?
Answer: If the cell has not properly copied its chromosomes, an enzyme called cyclin dependent kinase, or CDK, will not activate the cyclin, and the cell cycle will not proceed to the next phase. The cell will undergo cell death.
Which is the correct order of cell cycle?
So the correct order of stages in the cell cycle is G1 → S → G2 → M. Some cells do not divide repeatedly and enter an inactive stage called G or quiescent stage after exiting G1.
Do daughter cells have 46 chromosomes?
Explanation: If a human cell undergoes mitosis its daughter cells will have 46. … There is no change in chromosome number in mitosis.
How many chromosomes do daughter cells have after meiosis 1?
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
