Question

In meiosis
(1) Division of nucleus occurs twice and replication of DNA only once
(2) Both division of nucleus and replication of DNA occurs twice
(3) Both division of nucleus and replication of DNA occurs once
(4) Division of nucleus occurs once and replication of DNA is twice

Answer 1

In meiosis Division of nucleus occurs once and replication of DNA is twice.

It is a eukaryotic cell division that gives four daughter cells.

Through meiosis new combinations of the material of varied genes are formed which are responsible for DNA exchange between the chromosome pairs.  

Two rounds of nucleus division occur in the process.
