Mitosis & Meiosis Flashcards
1
Q
Explain Mitosis
A
DNA makes 2 identical copies of a cell
makes 2 sister chromotids
homologous pair
half way through mitosis sister chromotids separate
chromosomes are lined up so they can be separated easier
2 identical sister cells are produced
2
Q
Explain Meiosis
A
chromosomes from mum and dad
homologous pairs separated so chromosomes are lined up
4 daughter cells made
homologous pair separated then two sister chromotids separated
3
Q
how does a chromosome become two strands?
A
by the dna replicating
4
Q
why must a chromosomes become two strands before the cell divides
A
so that the offspring receives a complete set of the same genetic material
5
Q
what type of cell division produces gametes
A
meiosis
