Replication of genetic material in the mother cell 2. Separation of the replicated genetic material 3. These proteins are involved in packaging the DNA tightly so that it will all fit into the cell. B. You have 46 chromosomes , arranged in 23 pairs - 1 set from mom and 1 set from dad. C. Must be replicated and divided so that the genetic information can be transferred to each new cell.
Chromosomes replicate a.
Each chromosome is now made up of two identical sister chromatids joined at a centromere . There is now twice the genetic information , although the same number of chromosomes as before. Centrioles replicate 4. Nucleolus is visible . B. Prophase 1.
