cell cycle pt.1 Flashcards
repeated pattern of growth & division that occurs in eukaryotic cell.
cell cycle
what are the three phases of cell cycle?
Interphase, M-phase, and G^0
It is for cell growth, and in the end of this phase cell has 2 full sets of DNA (23 chromosomes) and is large enough to begin division process.
Interphase
It is for cell division; makes 2 out of 1 cell
M-Phase
DNA Replication
S-Phase
Mitotic Division
M-Phase
G^0
Resting
G^1
Growth
G^2
Additional Growth
DNA becomes nucleosome, the process of condensation will become supercoils and then become chromosomes.
Synthesis Phase
Single DNA strands (chromatids) will replicate and become homologous chromosome (sister chromosome).
Synthesis Phase
if the DNA wants to cell divide it will _______?
Duplicate DNA strands and make double helix
Double helix -> H_____ -> C___ -> S____ C____ -> C____
Histones, Coils, Super Coils, Chomosome
after cell replication the 23 pairs of chromosomes will become?
46 pairs of chromosomes
4 Distinct events, for further condensation of DNA
Prophase
Chromosome condense and more visible, and the nuclear membrane disappear.
Prophase
Centrioles have separated and taken position on opposite pole of cell, and the spindle fiber form and radiate towards center.
Prophase
Chromosome lines up across the middle of cell.
Metaphase
Spindle fiber connect centromere of each sister chromatids to pole of cell.
Metaphase
shortest phase
Metaphase
centromere joins sister chromatid split and it will separate and become individual chromosome.
Anaphase
Separate chromatids move to opposite pole of cell.
Anaphase
It is the last phase
Telophase
Chromosomes that consist of single chromatid uncoil.
Telophase
