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, DNA replication occurs. DNA replication is the process where the cell makes an identical copy of its DNA. If an error occurred during DNA replication (such as a mutation in the DNA sequence), it could lead to incorrect genetic information. This incorrect genetic information could result in abnormal cell function. For example, it could cause the production of a non - functional protein. If the error is not corrected, it could be passed on to daughter cells during cell division. This could potentially lead to problems 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. Prediction: Abnormal cell function (e.g., non - functional protein production, potential for cancer if cell growth/division genes are affected and error not corrected).
