Ch 1 Cell Division Flashcards
1
Q
What happens during interphase?
A
Cell grows, functions, and gets ready for cell division. (Mitosis)
Makes copy of DNA.
2
Q
What is a chromatid?
A
A copy of DNA held together by a centromere.
3
Q
What are the phases of mitosis?
A
Prophase
Metaphase
Anaphase
Telophase
4
Q
What happens during prophase?
A
Chromatin could up into chromosomes Nuclear envelope disappears Nucleolus disappears Centrioles move to opposite sides of the cell Mitotic spindle forms between centrioles
5
Q
What happens during metaphase?
A
Chromosomes line up in middle of cell
6
Q
What happens during anaphase?
A
Centromeres break and chromosomes are pulled apart
7
Q
What happens during telophase?
A
Chromosomes uncoil into chromatin
Nuclear envelope reappears
Nucleolus reappears
Mitotic spindle disappears
8
Q
What is cytokinesis?
A
Division of the rest of the cell after mitosis
9
Q
What is interphase?
A
The time in between cell divisions.
