Which of the following is not a characteristic of meiosis?
Options
- AIt involves two stages of DNA replication one before meiosis-I and another before meiosis-II.
- BIt involves recombination and crossing over.
- CCentromeres divide during anaphase-II.
- DTerminalisation occurs during diakinesis.
Correct answer
A. It involves two stages of DNA replication one before meiosis-I and another before meiosis-II.
Step-by-step 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.
