Mieosis Flashcards
1
Q
G1 Phase
A
INTERPHASE: the cell grows and develops
2
Q
S phase
A
INTERPHASE: the DNA of each chromosome is replicated to form sister chromatids
3
Q
Prophase 1
A
chromosomes condense and pair up during synapsis to form a tetrad. Crossing-over between paternal and maternal chromatids results in swapping of genes.
4
Q
Metaphase 2
A
chromosomes line up individually along the metaphase plate
5
Q
Anaphase 2
A
sister chromatids separate and are pulled towards opposite poles of the cell
6
Q
Telophase 2
A
nuclear membranes from around each set of chromosomes while they decondense
7
Q
Cytokinesis
A
splits the chromosome sets into new cells, forming four haploid cells in which each chromosome has one chromatid (sperm or egg)
