|
interphase
|
non-reproducing stage where the cell spends most of its time; this stage begins when cell reproduction is over

|
|
binary fission
|
process where prokaryotes replicate their DNA & distributes 2 copies to daughter cells
|
|
|
homologous/homologues
|
> homologous: similar in structure, in function, or both; the more homologous structures shared by different kinds of organisms, the closer their relationship
> homologues: in diploid cells, the two members of each pair of chromosomes that carry DNA with information for corresponding traits |
|
|
diploid/haploid
|
> diploid: cells haveing 2 of each chromosome
> haploid: cells havingonly one chromosome from each homologous |
