- chromosome
- a replicated DNA helix=two chromatids
- 96
- chromatids are in human somatic cells after replication
- Anaphase 2
- chromosomes split; chromatids separate; dyad to monad; paired chromatid divides into single chromatid
- Metaphase 2
- chromatids line up on the equatorial plane; centromeres attach to the spindle
- mutations
- changes in chromosome number and changes in chromosome structure; causes genetic variations
- 46
- chromatids are in human somatic cells before replication
- 46
- chromosomes are in somatic cells after replication
- chromatin
- uncoiled chromatid
- Telophase 2
- cytokinesis occurs; nuclear membrane returns; chromatids uncoil
- chromatid
- one dna helix tightly coiled in the process of reproducing the cell
- 23
- homologous pairs in prophase 1 of meiosis
- 23
- chromosomes are present in metaphase 2 in the human
- 23
- chromatids in the human gamete at the end of meiosis
- 23
- chromosomes are in somatic cells before replication
- Prophase 2
- nucleoli disappear.spindle forms.cells are haploid no synapsis. no crossing over. no nuclear membrane. similiar to mitosis
- 46
- chromatids are present in metaphase 2 in the human
