Calculation of DNA strands in G2 Phase
To determine the number of DNA strands in a cell's nucleus during the G2 phase, we need to understand the process of DNA replication.
DNA Replication in G2 Phase
During the G2 phase of the cell cycle, the cell prepares for division by replicating its DNA through the process of DNA synthesis. This results in the formation of two identical copies of each chromosome, known as sister chromatids.
Chromosomes and DNA Strands
In the G1 phase, the cell had four chromosomes. Each chromosome consists of a single DNA molecule. However, after DNA replication in the G2 phase, each chromosome now consists of two sister chromatids, making a total of eight chromatids.
Number of DNA Strands
Since each chromatid contains a DNA molecule, the total number of DNA strands in the nucleus during the G2 phase would be eight times the original number of chromosomes. Therefore, in this case, with four chromosomes in the G1 phase, there would be a total of eight DNA strands in the nucleus during the G2 phase.
In conclusion, a cell of root Apex meristem with four chromosomes in the G1 phase would have eight DNA strands in its nucleus during the G2 phase after DNA replication.
