Eukaryotic Cell: Cell Cycle Flashcards
What is interphase?
The LONG part of the cell cycle
made of G1 (gap, growth)
S (DNA synthesis)
G2 (gap, growth)
What is mitosis?
Cell division
made of…
prophase
metaphase
anaphase
telophase
What happens during prophase?
prophase = PREPARE
chromosomes condense
mitotic spindle forms
nuclear membrane breaks down
centrioles move to poles
What happens during metaphase?
metaphase = MIDDLE
chromosomes line up in middle
What happens during anaphase?
anaphase = APART
sister chromatids pull apart
move to opposite sides
What happens during telophase?
prophase in REVERSE
chromosomes de-condense
nuclear membrane reforms
mitotic spindle breaks down
What hppens during G1 and G2?
growth
make organelles
increase in size
What happens during S phase?
DNA synthesis
What are sister chromatids?
duplicated copies of chromosomes
What is the centrosome?
region that organizes microtubules
contains a pair of centrioles
What is the centromere?
this is part of one chromosome
that links two sister chromatids
What is the kinetochore?
a protein at the centromere (which joins sister chromatide)
where mitotic spindle fibers attach to pull them apart
