Binary Fission
The origins of the two newly replicated chromosomes move away from each other and toward opposite ends of the cell
Process of binary fission
Prokaryotes
Replication
S stage
Interphase
G1, S, G2
2n=12
n=____ types
6
n stands for
The different types of chromosomes
Gives homologous chromosomes
1 male parent and 1 female parent
Cell growth, normal functions
G1 stage
Checkpoints
G1/s, G2/M, and spindle assembly
3n=18
n=____ types; # distinct chromosomes
6; 12
Diploid
Having two sets of chromosomes
Eukaryotes
Yields two identical diploid daughter cells
M stage
Binary fission
Replication of DNA, separation of replicated chromosomes to sides, and cell division
2n=44
How much DNA?
8
Sister chromatids
Two copies of a chromosome that are held together by the centromere
Makes sure cell is not damaged and checks for growth factors
G1/s checkpoint
Cell prepares for division
G2 stage
Cellular reproduction
Prokaryotes and eukaryotes
3n=18
n=___ types; total chromosomes
6; 18
Homologous Chromosomes
Two chromosomes that carry the same set of hereditary characteristics
Meiosis
Eukaryotes
G0 stage
Mitosis
DNA replication, sister chromatids separate, and cell divides
2n=44
# homologous chromosomes
