Cell cycle
What’s the point of the cell cycle?
The point of the cell cycle is for the cell to grow and develop and eventually split to form two identical cells through mitosis and cytokinesis.
double helix
full name of DNA
Deoxyribonucleic acid
# of chromosomes in the human body
46
Mitosis
divison of cells
In which phase do cells spend the most time?
G1
DNA is composed of.... nitrogenous bases
4
Segments of DNA which code for specific proteins are called
Genes
loose DNA present during interphase
chromatin
body cells (not egg or sperm)
somatic
How is the cell different in G1 versus G2?
The DNA replicated in the S phase.
DNA is composed of 4 nitrogenous bases, what are they?
They are thymine, adenine, guanine, cytosine.
condensed strand of DNA
chromosome
.... chromosomes come from the biological mother.
23
The two copies of DNA will attach to each other through a structure called the
centromere.
Do prokaryotes go through a complex cell cycle?
No, prokaryotes do not have organized DNA in a separate nucleus, so they do not undergo the same complex cycle.
Adenine and.... are bonded bond together through hydrogen bonds.
thymine
DNA is a polymer of
nucleotides
Pair #23 can be XX or..
XY
Genetic code can be more easily read to guide cell processes
Chromatin
A chemotherapy drug interferes with the cell’s ability to replicate DNA properly. Which phase of the cell cycle is this drug targeting?
S
Guanine and... are bonded together through hydrogen bonds.
cytosine
Which nitrogenous bases are purines?
adeine and guanine
When DNA replicates, two... copies of DNA are created.
identical
replicated DNA
sister chromatids
