If the DNA content of an onion tip cell is 2C at the end of the M-phase, then its DNA content would be 4C at the end of the S-phase. During the S-phase of the cell cycle, DNA replication takes place, and the amount of DNA in the cell doubles. At the end of the S-phase, each chromosome consists of two identical sister chromatids, which are held together at the centromere. Thus, the DNA content of the cell is doubled from the G1 phase (1C) to the end of the S-phase (2C), and it remains the same through the G2 phase. Therefore, if the DNA content of an onion tip cell is 2C at the end of the M-phase, it means that the cell has completed the mitotic division and has two sets of chromosomes. If the cell then enters the S-phase, it will replicate its DNA, resulting in the DNA content of 4C at the end of the S-phase.

If a cell has c at end of G1 phase and 2c at end of s phase then remains same at G2 and M phase is 2c ,so answer is 2c at end of s phase because it completed the cell cycle
why it go to second cell cycle

If the DNA content of an onion tip cell is 2C at the end of the M-phas...
Explanation:
Given: DNA content of an onion tip cell is 2C at the end of the M-phase.
During S-phase:
- The DNA content of a cell doubles during the S-phase.
- The DNA content of a cell at the end of the S-phase can be calculated by multiplying the DNA content at the end of the M-phase by 2.
Calculation:
- DNA content at the end of the S-phase = 2C x 2 = 4C
Therefore, the DNA content of an onion tip cell at the end of the S-phase would be 4C.
