- Somatic stem cells divide by mitosis for more somatic cells
- Germline stem cells divide by mitosis and mieosis
- Mitosis produces more Germline stem cells and Mieosis produces haploid gametes
- Mitosis - 2 diploid daughter cells, maintains chromosome complement, produce cells for self-renewal/ growth ad repair, somatic and germline
1. chromosomes in nucelus copied and chromosomes condense and form 2 identical chromatids
2. nucleus disintegrates and spindle fibres line chromatids at equator
3. chromatids separate and move to opposite sides of the cell
- Mieosis - 4 haploid daughter cells, produces gametes and reproductive cells, germline
1. chromosomes in nucleus copied and chromosomes condense and form 2 identical chromatids
2. Chromosomes find match, exchange DNA , nuclues disintegrates, spindle fibres make chromatids line at equator
3. 1st division -> matching pairs separate, 2nd division -> separate into 4
