The Cell Cycle Flashcards
process by which cell replicate and make two new cells
cell cycle
important task of cell cycle
- it must grow
- it must physically split into two new daughter cells
- it must copy its genetic material
importance of the cell
- it is essential in forming new plants
- it makes new life possible
- it is vital in the process of healing and tissue repair
two major phases of cell cycle
- interphase
- mitotic phase
non-dividing stage
interphase
interphase
- first gap (G1) Phase
- synthesis of DNA (S Phase)
- second gap (G2) Phase
- gap zero (G0) Phase
cell growth
metabolically active
period of growth
G1 Phase
DNA replication
replicates a chromatin into a full chromosome
S Phase
where spindle fiber attached
sister chromatid attached through this
centromeres
- synthesizes proteins necessary for chromosomal manipulation
- duplication of organelles
G2 Phase
“resting phase”
not be able to reproduce
G0 Phase
cell division
dividing stage
mitotic phase
two kinesis under mitotic phase
karyokinesis & cytokinesis
division of nucleus
karyokinesis
division of cytoplasm
cytokinesis
under karyokinesis
P, M, A, T
- prophase
- metaphase
- anaphase
- telophase
longest phase of mitosis
prophase
chromosomes align in the middle or center of the cell
metaphase
chromatids breakdown, move away from each other
= apart
anaphase
cleavage furrow forms in the center of the cell
returns to prophase stage to reproduce once again
telophase
final preparation for division
G2 Phase
