mitosis - CORRECT ANSWERS cell division producing genetically identical
daughter cells
- start and end as diploid cells
meiosis - CORRECT ANSWERS cell division producing 4 genetically unique
gametes
- begin as diploid, end as haploid
interphase - CORRECT ANSWERS - G1: active gene expression, prep for DNA
synthesis
- S: DNA doubles, sister chromatids for each chromosome
- G2: cells prepare for division
stages of mitosis - CORRECT ANSWERS - prophase: chromosome condensation,
attach to tubules
- metaphase: chromosomes align at center
- anaphase: tubules pull sister chromatids apart
- telophase: cells split to two daughter cells
what is the number of nuclear DNA molecules in metaphase of mitosis? -
CORRECT ANSWERS 46 chromosomes, each with 2 sister chromatids = 92 total
chromatids
what is the number of nuclear DNA in telophase/cytokinesis of mitosis? -
CORRECT ANSWERS 46 chromosomes, each with 1 sister chromatid = 46 total
chromatids

stages of meiosis I - CORRECT ANSWERS - prophase I: homologs form tetrads
and share DNA (recombination) at chiasmata
- metaphase I: homologs align at center
- anaphase I: homologs separate
- telophase I/cytokinesis: cells split into 2 daughter cells
stages of meiosis II - CORRECT ANSWERS - prophase II: breakdown of nuclear
envelope of 2 cells, chromosome condensation
- metaphase II: sister chromatids align at center
- anaphase II: sister chromatids separate
- telophase II/cytokinesis: both cells split in 2; 4 unique daughter cells
what is the number of nuclear DNA in metaphase I in meiosis? - CORRECT
ANSWERS 46 chromosomes with 2 sister chromatids each = 92 total
chromatids
what is the number of nuclear DNA in telophase I in meiosis? - CORRECT
ANSWERS 23 chromosomes with 2 sister chromatids each = 46 total
chromatids
- 1/2 amount of DNA present after S phase
what is the number of nuclear DNA in telophase II in meiosis? - CORRECT
ANSWERS 23 chromosomes with 1 sister chromatid each = 23 total chromatids
- 1/4 amount of DNA after S phase
