CELL DIVISION

THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
At the end of the cell cycle, there are two genetically different cells. True or False
A
True
B
False
Explanation: 

Detailed explanation-1: -Mitosis divides the nucleus into two nuclei, followed by cytokinesis which divides the cytoplasm. Two genetically identical daughter cells result.

Detailed explanation-2: -In mitosis, the end product is two cells: the original parent cell and a new, genetically identical daughter cell. Meiosis is more complex and goes through additional phases to create four genetically different haploid cells which then have the potential to combine and form a new, genetically diverse diploid offspring.

Detailed explanation-3: -Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies-or ‘replicates’-its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

Detailed explanation-4: -Each daughter cell has half the number of chromosomes as compared to their parents (one copy of each chromosome). The resulting cells from meiosis are not genetically identical because of the recombination of genes that occurred during prophase 1. Sex cells in humans are produced by meiosis.

Detailed explanation-5: -There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division, ” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells.
