Cell division Intro
Does the cell grow in size before it divides?
yes
where in the cell do we find DNA
nucleus
What are chromosomes made of?
DNA
interphase 90%
List the four steps of Mitosis, in order
PMAT
growth, repair, replacement
What are the four DNA base pairs? & how do they match up?
A - T
C - G
A small section of DNA on a chromosome is a
gene
10%
When are the chromosomes lined up at the metaphase plate
Metaphase
the cell cycle is a cycle, because at the end of each round,
the two daughter cells can start the exact same process over again
DNA is duplicated during
interphase
Explain the difference between chromosomes and sister chromatids
Two sister chromatids make up one chromosome
List the 3 things that happen during interphase
normal cell activity, cell grows, and DNA duplicates
When are the chromosomes pulled apart to opposite sides of the cell
Anaphase
When are cells dividing?
all the time!
What is DNA made of
base pairs (A, T, C, and G) & sugar phosphate backbone
genome
What happens in cytokinesis?
The cell is split into two new daughter cells
Which step of Mitosis includes nuclear membranes reforming around each set of chromosomes
telophase
what is an example of abnormal growth of cells?
1%
How many chromosomes do humans have in their lung cells?
46 chromosomes
After cytokinesis, what are the two new cells called?
In which of the four steps do the chromosomes condense?
Prophase
