How much DNA was in the cell at completion of the S-phase?

Answer 1

S phase
The S phase, short for synthesis phase, is a period in the cell cycle during interphase, between G1 phase and the G2 phase. Following G1, the cell enters the S stage, when DNA synthesis or replication occurs. At the beginning of the S stage, each chromosome is composed of one DNA double helix molecule, which is called a chromatid. At the end of this stage, each chromosome has two identical DNA double helix molecules, and therefore is composed of two sister chromatids. During S phase, the centrosome is also duplicated. These two events are unconnected, but require many of the same factors to progress. The end result is the existence of duplicated genetic material in the cell, which will eventually be divided into two.

Damage to DNA often takes place during this phase, and DNA repair is initiated following the completion of replication. Incompletion of DNA repair may flag cell cycle checkpoints, which halts the cell cycle

Answer 2

After the completion of S-phase there will be two copies of DNA

Answer 3

during s phase the DNA is duplicated ie there will be two copies of DNA since in the s-phase the process of replication take place where the DNA is duplicated thus in S_phase we contain two copies of dna

Answer 4

S section is the component to interphase whilst DNA DOES mirror. this is whilst helicase opens up the DNA strand to start up elongation. consequently, DNA might purely mirror for the time of S component to interphase of the cellular cycle. desire that helped :) !
