Mitosis And Meiosis Flashcards
Mitosis
Cell division
What are the stages of mitosis
Prophase, metaphase anaphase, telophase, cytokinesis
Prophase
.chromosomes are replicated.
Metaphase
Pairs of sister chromatids are aligned halfway between poles of metaphase plate
Anaphase
Connections between the pairs of sister chromatids are broken
Telophase
Nuclear membranes reform to produce two separate nuclei
Cytokinesis
Division of the cytoplasm.
Meiosis
Production of gametes
What happens before meiosis
It goes through interphase
What is the steps of meiosis
Prophase l, metaphase l, anaphase l, telophase l
Prophase l
Starting cell is 2n. Homologous chromosomes Cross over
Metaphase l
Pairs line up at the metaphase plate
Anaphase 1
Homologous separates to opposite ends of cell.
Telophase I
New haploid cells are forming. Each chromosome has two sister chromatids that are non-identical
Meiosis ll
No S phase
