stages of cell cycle
what is the first phase
interphase
if a cell has 67 chromosomes is it gamete or somatic
gamete
what is the condition when a person is born with an extra chromosome
Down Syndrome
what is the first phase of mitosis
prophase
how many chromosomes do people have
46
what percentage of the cell cycle is interphase
90%
somatic cells have 2 sets of chromosomes while gamete only have 1
what proteins wrap DNA
histones
what occurs during prophase
chromosomes condense, nucleoli disappear, spindle forms centrosomes separate
how many chromosomes are in the cell during anaphase
92
what is the second phase
synthesis
do you get more chromosomes from your mom or your dad
trick question: they're equal
what make up chromosomes
chromatin
what is metaphase
the cell begins to separate and the chromosomes line up
how many stages of mitosis are there
4
what is produced in large quantities during G2 phase
ATP
how do somatic cells divide
mitosis
what makes up chromatin
nucleosomes
what is anaphase
the sister chromosomes separate and cell elongates
whats the difference between mitosis and meiosis
mitosis separates somatic cells while meiosis creates gamete cells
what divides during mitosis
the nucleus
how do gamete cells divide
meiosis
where are the chromosomes located
the nucleolus
what happens during telophase and cytokinesis
the spindle breaks down and two nuclei form and the cleavage pinches the two cells apart
what is the genome
all of the cell's genetic information
