59. When does the DNA of the cells get duplicated during meiosis I and meiosis II?
A. The DNA is duplicated between meiosis I and meiosis II
B. The DNA is not duplicated during meiosis I and meiosis II
C. The DNA is duplicated during meiosis I
D. The DNA is duplicated during meiosis II
Answers
Explanation:
option c the DNA is duplicated during meiosis
Answer:
C (Meiosis consists of one round of DNA replication and two rounds of chromosome segregation.)
Explanation:
Not A because, Between meiosis I and meiosis II, CDK is partially inactivated and the spindle pole bodies are reduplicated. CDK is reactivated to drive meiosis II, during which sister chromatids are segregated.
Not B because, First thing to remember is that interphase is a stage associated with replication of DNA, and growth. Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. Hence between meiosis I and meiosis II , there is no interphase.
Not D because, Meiosis II begins with the 2 haploid cells where each chromosome is made up of two connected sister chromatids. DNA replication does NOT occur at the beginning of meiosis II.
