Cells - Chromosomes and Mitosis Flashcards
1
Q
What is a gene?
A
A gene is a section of DNA that codes for a specific characteristic e.g your eye colour.
2
Q
Define haploid and diploid.
A
Haploid - one copy of each chromosome.
Diploid - two copies of each chromosome.
3
Q
What is mitosis?
A
Process by which a cell divides.
4
Q
List the different stages of mitosis
A
Interphase ( cell growth), prophase, metaphase, anaphase and telophase.
5
Q
What happens in interphase?
A
Cell grows - DNA copied - 2 copies of each chromosome.
All organelle double.
6
Q
What happens in prophase?
A
Chromosomes condense - shorten and thicken.
7
Q
What happens in metaphase?
A
Chromosomes line up down the equator of the cell.
8
Q
What happens in anaphase?
A
Chromosomes pulled apart to the poles of the cell.
9
Q
What happens in telophase?
A
Cell splits in 2 - daughter cells.
