cell cycle and mitosis Flashcards
what does the cell cycle consist of
The mitotic phase and Interphase
what else does the cell do in interphase
carry out the functions of that particular cell type
what are the three stages of interphase divided into
- the G1 phase
- Synthesis phase
- G2 phase
what happens to cell organelles in G1
the cell replicates organelle such as mitochondria
what is required to help replicate organelles
a great deal of proteins
in G1 a high level of _________ and __________ occurs
transcription and translation
what happens to the size of the cell in G1
it increases
why does cell size increase in G1
to ensure that when the cell divides the two daughter cells are the correct size
what occurs in synthesis
during this phase all of the chromosomes are replicated, to do this the cell needs to synthesise a great deal of DNA
what occurs in G2 with energy stores
the cell replaces the energy stores used in S phase
what continues to occur in G2 which occured in G1
transcription and translation and cell growth
what happens to damaged chromosomes in G2
any damaged chromosomes are repaired in G2
what is the mitotic phase divided into
mitosis and cytokinesis
what happens in mitosis
chromosomes separate into two nuclei
what occurs in cytokinesis
cell divides into two
