B 2.1 Cell Division

Question 1

Describe the process of the cell cycle and mitosis

Answer 1

During the cell cycle the genetic material is doubled and then divided
into two identical cells.
Before a cell can divide it needs to grow and increase the number of
sub-cellular structures such as ribosomes and mitochondria. The DNA
replicates to form two copies of each chromosome.
In mitosis one set of chromosomes is pulled to each end of the cell and
the nucleus divides.
Finally the cytoplasm and cell membranes divide to form two identical
cells.
