Question

1. the model shows what happens to genetic material before and after interphase.

write your answer on the lines.
compare the differences between the chromosome structures before and after interphase. include in your comparison the process that causes the difference.
predict what would happen if an error occurred during the process you identified.

Explanation:

Before interphase, each chromosome has 1 chromatid. After interphase, each chromosome has 2 chromatids. This is because during interphase (specifically the S - phase), DNA replication occurs. DNA replication is the process that causes the change. If an error occurred during DNA replication (such as a mutation), it could lead to incorrect genetic information. This could result in cells with abnormal genetic material. For example, if the error is not corrected, it could lead to cells that do not function properly. In some cases, it could lead to diseases like cancer if the mutation affects genes that regulate cell growth and division.

Answer:

Before interphase: 1 chromatid per chromosome. After interphase: 2 chromatids per chromosome. Process: DNA replication in interphase (S - phase). If error in DNA replication: Abnormal genetic information, possible cell malfunction or diseases (e.g., cancer if growth - regulating genes affected).
