QUESTIONS VERIFIED ANSWERS A+
◉ what does mitosis produce?
Answer: goes from one diploid to two diploids
produces two identical diploids
◉ what is the purpose of meiosis?
Answer: sexual reproduction in gamete and sex cells
◉ what does meiosis produce?
Answer: goes from two diploid cells to four haploid
produces four different haploids
◉ genetic material in bacteria consists of what?
Answer: one circular DNA molecule
◉ prokaryotic cells divide through what process?
Answer: binary fission
◉ eukaryotic cells divide through what process?
Answer: mitosis
,◉ steps of the prokaryotic cell cycle
Answer: 1) circular DNA double helix is attaches to the plasma
membrane at one point
2) DNA replicates and the two DNA double helices attach to plasma
membranes at nearby points
3) New plasma membrane is added between attachment points, pushing
them apart
4) plasma membrane grows inward
5) parent cells divides into two daughter cells
◉ chromosomes 1-22 are called?
Answer: autosomes
◉ chromosome 23 is called?
Answer: sex linked chromosome
this chromosome determines the sex
◉ interphase takes up what percentage of the eukaryotic cell cycle?
Answer: 90%
◉ during cytokinesis in what type of cell the cell wall not allow the cell
to pinch?
Answer: plant
, ◉ what happens during the S phase of interphase?
Answer: chromosome replication and synthesis
◉ what is the order of cell division in mitosis?
Answer: prophase
metaphase
anaphase
telophase
cytokinesis
◉ what happens in prophase of mitosis?
Answer: early - duplicated chromosomes begin to condense
late - new microtubules are assembled, nuclear envelope begins to break
up
◉ what happens in metaphase of mitosis?
Answer: spindle microtubules form and attach to the two sister
chromatids of each chromosomes
all chromosomes meet up in the middle
◉ what happens in anaphase of mitosis?
Answer: sister chromatids are pulled apart, making each chromatid a
chromosome
