Guida verificata passo dopo passo1
Understand that a human somatic cell is diploid, meaning it contains two sets of chromosomes, one from each parent, for a total of 46 chromosomes.
During the G2 phase of the cell cycle, the cell has already completed DNA replication, which occurs during the S phase. This means each chromosome has been duplicated.
Each duplicated chromosome consists of two sister chromatids. Therefore, each of the 46 chromosomes is made up of two chromatids.
To find the total number of chromatids, multiply the number of chromosomes (46) by the number of chromatids per chromosome (2).
The calculation is: . This will give you the total number of chromatids present in the cell during the G2 phase.
