Q

each segment of DNA is known as what

A

Gene

15
Q

what happens during MITOSIS

A

during MITOSIS chromosomes got through 5 phases

16
Q

what are the 5 phases of mitosis

A

PH 1: phrosphase; PH 2: metaphase; PH 3: Anaphase PH: 4 telophase PH 5: cytokines

16
Q

what happens during each phase

A

phase 1 prophase- chromosomes appear

16
Q

what happens during each phase

A

phase 2 metaphase- chromosomes line up

17
Q

what happens during each phase

A

phase 3 anaphase- chromosomes separate

18
Q

what happens during each phase

A

Phase 4 telophase- chromosomes pinch

18
Q

what happens during each phase

A

phase 5 cytokines- two new daughter cells form

18
Q

how many chromosomes do humans sex cells have

A

they have 23 chromosomes in each sex cells

19
Q

how many chromosomes do human cells have

A

46 chromosomes in each human cell

20
Q

what do you call a cell with a full set of chromosomes (46)

A

a DIPLOID cell

21
Q

what do you call a cell with HALF a set of chromosomes (23)

A

a HAPLOID cell

22
Q

Do bacteria cells go through mitosis like eukaryotic cells

A

no bacteria doesn’t have a nucleus

22
Q

how do bacteria cells divide

A

bacteria cells split in half called binary fission

22
Q

why do our body cell divide

A

our body cells dive to replace dead cells to grow and develop

23
