Question

if a cell has 60 pg of DNA and 25 chromosomes in its G1 phase, how much DNA and chromosomes are in the anaphase cell?

Answer 1

G1 is an intermediate phase present inbetween the end of cell division in mitosis and the beginning of DNA replication during S phase. During this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication. While Anaphase is the fourth phase of mitosis. In this process two identical daughter cells get form by separating the duplicated genetic material carried in the nucleus of a parent cell.

As per the picture given bellow,:

the genetic material(DNA) get start to double during S-phase and get separate at telophase(last step) during division of cell. Hence the cell has number of chromosomes in Anaphase are 50 and 120pg of DNA.

160p9 DNA, I number will divide into 2 7 & again in each cell! further cells, divide into 2 cells Peloph GL 25 chromosomes cells Telophase 1 [120 pg DNA - Anaphase Iso chromosomes M- cell cycle Metaphase est After cell cycle it will be in Anaphase where the nubeber get double ) prophase
