WEEK 4:
Chromosomes, Cell Cycle + Intro To its Regulation
| Question | Answer |
|---|---|
| meiosis | cell division reducing somatic quantity of DNA found in gametes |
| leptotene | prophase I- chromatin condenses form chromosome (not sister chromatids), along length chromosomes visible |
| zygotene | prophase I- homologous chromosomes (maternal-paternal) pair together forming bivalents + split into sister chromatids + develop local alignment sites (synapsis) between chromatids of H-pairs (form tetrad) |
| pachytene | prophase I- synapsis complete (crossing over) form chiasma- gene exchange between H-pairs (more likely along long distance) |
