Flashcards in Cell Division Deck (14)
Needs for cell division
Growth, wound repair, asexual reproduction
What must happen before a cell divides
Go through cell cycle checkpoints
Grow to sufficient size
What phases make up interphase?
G1, S, G2
Normal activities of the cell are performed
This is when DNA doubles
additional cell growth, organelles are replicated
When do the number of chromosomes double?
How long is one cell cycle?
Around 24 hours
How do microtubules move chromosomes?
kinectochore fibers break down the microtubules which shortens them
and this pulls the chromosomes apart
single double stranded DNA sequence (before S)
composed of chromatin
What happens after DNA replication?
There are two sister chromatids but still one chromosome
2 double strands
What are 2 sister chromatids held together at?
What happens during anaphase?
2 sister chromatids are separated which creates 2 different chromosomes each with 1 sister chromatid
