Question

DNA replicates in the ____ of the cell cycle​

Answer 1

DNA replicates in the eukaryotic of the cell cycle .

Answer 2

Answer

DNA replication takes place in S phase of cell cycle.

In the S phase

$\implies$2C = 4C

$\implies$2N = 2N

where

$\longrightarrow$2C no. of DNA.

$\longrightarrow$2N no. of chromosome.

Interphase -

$\implies$It is a complex of changes that occur in a newly formed cell before it is able to divide.

$\implies$It involves replication of DNA and synthesis of nuclear proteins and duplication of centrioles.

$\implies$Synthesis of energy rich components also takes place.

It occurs in three stages -

i) $G_1$( First Gap Phase ) $\longrightarrow$ In this phase the cell increases in size and synthesis of RNA, carbohydrates, proteins and lipids occur.

ii) S (synthesis phase) $\longrightarrow$ This is DNA replication, centriole replication phase

iii) $G_2$( Second Gap Phase )$\longrightarrow$ In this, DNA repair and synthesis of RNA ,spindle fibres (tublin) and duplication of cell organelle takes place.
