Biology Question on cell cycle and cell division
Which of the following is not a characteristic of meiosis?
A
It involves two stages of DNA replication one before meiosis-I and another before meiosis-II
B
It involves recombination and crossing over
C
Centromeres divide during anaphase-II
D
Terminalisation occurs during diakinesis
Answer
It involves two stages of DNA replication one before meiosis-I and another before meiosis-II
Explanation
Solution
Meiosis has two M-phases each with its own karyokinesis and cytokinesis. As a result, chromosome number is halved. The transition period between M-phase I (meiosis I) and M-phase II (meiosis II) is short and without DNA replication. It is called interkinesis.
