What is the cell cycle?
The sequence of events where a mother cell grows, duplicates DNA, and forms daughter cells.
What phases does the cell cycle include?
Interphase (G1, S, G2) and phase M (mitosis and cytokinesis).
What distinguishes homologous chromosomes from sister chromatids?
Homologous chromosomes are paired chromosomes of the same type, sister chromatids are two copies of one replicated chromosome.
In notation, what does A represent?
A represents the number of homologous chromosome sets.
Cell cycle phases
Interphase (G1, S, G2), M phase (mitosis, cytokinesis)
Semi-conservative replication
Chromosomes duplicated without changing number
Homologous chromosomes
Paired chromosomes of same type
Sister chromatids
Copies of one replicated chromosome
Mitotic phases sequence
Prophase, prometaphase, metaphase, anaphase, telophase, cytokinesis
Mitosis outcome
Two genetically identical diploid cells
Meiosis purpose
Reduce chromosome number; genetic diversity
