How many chromatids are in interphase G2?
There are 46 individual chromosomes in each cell. After replication there are a total of 46 chromosomes, with 92 individual chromatids, in each cell. G2 Phase: During G2, the cell makes proteins that are used in cell division.
How many chromatids would the cell with 12 chromosomes have in the G2 phase of its cell cycle?
Thus at the end of the premitotic gap phase or second growth phase, the number of chromosomes remains 12 but has 24 sister chromatids before the mitosis.
What happens in G2 phase of interphase?
G2 Phase. The G2 phase is the time during which a cell replicates its organelles in preparation for mitosis. Not only does the DNA need to be divided, but so do the organelles. G2 is the last chance for the cell to make more protein in preparation for division.
What will be the DNA content of the cells at G1 after S and at G2 if the content after M phase is 2c?
Therefore when DNA content after m phase of a cell is 2c than in the G1 phase it will remain 2c because no replication takes place in this phase. In S phase the DNA content will become 4c because DNA replication takes place in this stage and in the G2 phase the DNA content will remain 4c.
How many DNA molecules are in the G2 phase?
of DNA molecule in G2 will be =8. No. of chromosome= 4 and as two DNA molecules are held at a common centromere.

|After cytokinesis of Mitosis||4||4|
What phase is 92 chromatids?
The S phase is where DNA is duplicated and there become 92 chromatids.
How many chromatids does a chromosome have in G1?
In G1, each chromosome is a single chromatid. In G2, after DNA replication in S phase, as cell enter mitotic prophase, each chromosome consists of a pair of identical sister chromatids, where each chromatid contains a linear DNA molecule that is identical to the joined sister.
