2.3: Eukaryotic cell cycle and division

#2.3i

Know that the cell cycle is a regulated process in which cells divide into two identical daughter cells, and that this process consists of three main stages: interphase, mitosis and cytokinesis.

#2.3ii

Understand what happens to genetic material during the cell cycle, including the stages of mitosis.

#2.3iii

Understand how mitosis contributes to growth, repair and asexual reproduction.

#2.3iv

Understand how meiosis results in haploid gametes, including the stages of meiosis.

#2.3v

Understand that meiosis results in genetic variation through recombination of alleles, including independent assortment and crossing over.

#2.3vi

Understand what chromosome mutations are, as illustrated by translocations.

#2.3vii

Understand how non-disjunction can lead to polysomy, including Down’s syndrome, and monosomy, including Turner’s syndrome.
