how many chromosome will the cell have in G1 , after S and M phase respectively if it has 14 chromosome at interphase
Answers
Answer:
Explanation:
The number of chromosomes from G1 to metaphase remains same while the number of DNA and chromatids changes.
So, the number of chromosomes in G1, S and M will be 14 , 14 and 14 respectively.
From G2 the number of chromosomes changes in case of meiosis by as in case of mitosis the chromosome number doesn't changes upto to the mitosis(M).
Hence we must note the difference between chromosomes and chromatids .
Since in mitosis also the number of chromatids reduces after G1.
In the G1 phase there will be 14 chromosomes present as there is no replication of DNA takes place in the phase.
Explanation:
After the S phase DNA content changed and doubles but the chromosomes number remains same i.e 14.
After the M phase chromosome number will be 28 and the each daughter cell has the same number of chromosome i.e 14.
The number of the chromatids reduced at the ends of the G1 phase of the mitosis.
