🤓 Based on our data, we think this question is relevant for Professor Pelton's class at UMN.
A diploid cell has 14 chromosomes. How many chromosomes and sister-chromatids are found in that cell at each stage of the cell cycle in mitosis?
G1 is the part where the cell has just finished dividing. So at G1, it would not have duplicated the cells yet. Thus, for this type of cell, there should be 14 chromosomes, 14 sister-chromatids in G1.
The chromosomes would then have been duplicated as identical sister chromatids in the S phase. Thus, in the G2 phase, there will be 14 chromosomes at 28 sister-chromatids.
