Question

Select the CORRECT statement related to mitosis

• A. Amount of DNA in the par nt cell is first halved and then distributed into two daughter cells
• B. Amount of DNA in the parent cell is first doubled and then distributed into two daughter cells
• C. Amount of DNA in the parent cell is first halved and then distributed into four daughter cells
• D. Amount of DNA in the parent cell is first doubled and then distributed into four daughter cells

Answer 1

Answer: (B)

During the S-phase (synthetic phase) of cell cycle, replication of DNA takes place on the template of the existing DNA. Hence, DNA content of the cell is doubled. During mitosis, it is equally distributed into two daughter cells, resuming the chromosome number of parent cell. On the other hand, during meiosis it is divided into four daughter cells each with half the chromosome number of parent cell.
