Question

the model represents the change in the dna content of a cell during the cell cycle. dna content during the cell cycle complete sets of dna in nucleus 2 1 cell cycle phase which part of the model represents the s phase? a i b ii c iii d iv

Explanation:

Step1: Recall S - phase function

In the S - phase of the cell cycle, DNA replication occurs, doubling the amount of DNA in the cell.

Step2: Analyze the graph

The graph shows the change in the number of complete sets of DNA in the nucleus. The phase where the DNA content increases from 1 set to 2 sets is the S - phase.

Step3: Identify the S - phase on the graph

Looking at the graph, the part where the DNA content rises from 1 to 2 is part II.

Answer:

B. II
