Cell cycle
What happens in G1.
Growth
where does replication take place in eukaryotes?
the nucleus.
what takes place before mitosis?
interphase.
what is the structure of all living things.
cells.
the nuclear membranes return, sister chromatids relax into a mass of chromatin in the nucleus.
telophase
what are the 4 phases in the cell cycle?
G1, S, G2, M
what has to happen to DNA before it divides?
has to be copied.
cells formed when the parent cell divides in two
daughter cells
what is half a diploid.
haploid
each chromosome attaches to a spindle fiber at its centromere, which still holds the chromatids together.
Metaphase.
where does DNA replication occur in prokaryotes?
cytoplasm.
where do new DNA strands form?
at the replication fork.
cell that is dividing.
parent cell
diploid
sister chromatids are being pulled apart as spindle fibers shorten.
anaphase.
what is the result of mitosis?
2 daughter cells.
what does semi conservative mean.
1/2 the same
the cell separates its DNA into two sets and divides, forming two new cells
Mitosis
what is between DNA replication and mitosis.
G2
the cell grows and makes a copy of its DNA (cell will not survive/function without a set of DNA)
interphase
what is the result of mitosis with chromosomes?
genetically identical daughter chromosomes.
which one is accurate:semi conservative, conservative, or dispersive.
semiconservative
what are some purposes of mitosis.
to replace old, dead, or damaged cells (ex. new skin cells replace old ones that die & flake off)
so living things can grow
for asexual reproduction (ex. bacteria)
what is the phases when the cell grows.
G1 and G2
what happens in the synthesis phase.
DNA replication.
