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
