Cell Cycle Flashcards
Normal metabolism and growth
G1 phase
DNA is copied
S (synthesis) phase
Normal function and preparation for cell division. Mitochondria, centrioles, and other organelles replicate
G2 phase
Division of the nucleus into two identical daughter cells. The two copies of DNA and cytoplasm are distributed to each daughter cell
M phase
Chromosomes of relatively same size and shape
homologous chromosomes
Segment of DNA encoding for specific cell instructions such as protein production
gene
Loosely wound form of DNA. Typically evident before M phase
chromatin
Chromosomes are long, loosely coiled, threadlike strands of DNA and protein
interphase
Chromosomes are not visible, except as chromatin granules
interphase
The nuclear membrane appears normal
interphase
DNA replication occurs
interphase
Centrioles replicate and begin to move apart toward end of the phase
interphase
Daughter centrioles move towards opposite ends of the nucleus
prophase
The nuclear membrane disappears
prophase
Nucleoli disappear
