Assume that you are dealing with a species in which the number of chromosomes in each somatic cell is 14. How many sister chromatids are present in the early telophase of mitosis?

• A. 7
• B. 14
• C. 28
• D. None of the listed responses is correct.
• E. 0

Answer: (E)

Verified step by step guidance

1. Understand that in mitosis, sister chromatids are duplicated chromosomes that are connected by a centromere.
2. In a species with 14 chromosomes in each somatic cell, there are initially 14 pairs of sister chromatids after DNA replication in the S phase.
3. During mitosis, these sister chromatids are separated into two daughter cells.
4. By the time the cell reaches early telophase, the sister chromatids have already been separated and are now individual chromosomes in each of the two new nuclei.
5. Therefore, in early telophase, there are no sister chromatids present because they have been separated into individual chromosomes.
