Cell Dna Chromosome Growth Replication Cycle Dividing Spread

In the growth and replication phase of the cell cycle, a cell enlarges, duplicates its DNA, and forms distinct X-shaped chromosomes, ensuring each new cell will receive a complete set of genetic material.

During growth and replication in the cell cycle, the cell increases in size, duplicates its DNA, and forms X-shaped chromosomes, ensuring each future cell receives a complete set of genetic material.

Front What happens during the Growth and Replication in the cell cycle?
Back
  1. In a cell that's not dividing, the DNA is all spread out in long strings.
  2. Before it divides, the cell has to grow and increase the amount of subcellular structures such as mitochondria and ribosomes.
  3. It then duplicates its DNA - so there's one copy of each chromosome for each new cell. The DNA is copied and forms X-shaped chromosomes. Each "arm" of the chromosome is an exact duplicate of the other.
