dna synthesis
The doubling of DNA (known as DNA synthesis or DNA replication) occurs during the "S (synthesis) phase" of the cell cycle. This is part of interphase, and occurs before mitosis (cell division).
Interphase is the metabolic or growth phase of a cell life cycle. The cell spend most of their life in this cycle preparing for cellular division.
During interphase chromosomes take the form of chromatin, an unravelled mess of DNA
S Phase of Interphase
DNA replicates during the S phase of interphase.
Replication is when DNA makes more DNA
DNA replicates during interphase.
During interphase, the thin and threadlike form of DNA in the nucleus is called chromatin. Chromatin consists of DNA wrapped around proteins called histones, which helps to organize and compact the genetic material within the cell.
DNA replication occurs during the S phase of interphase.
Interphase during mitosis if that's what you're asking. As in which stage?
The cell is prepared for division by doubling the DNA and centromeres and adding spindle fibers
During the S stage of interphase, DNA undergoes replication, where the DNA molecules are duplicated. This results in each chromosome consisting of two identical sister chromatids attached at a region called the centromere. This ensures that each daughter cell after cell division receives a complete copy of the genetic material.
