|
How does a cell cope with getting to large?
|
Mitosis (Normal cell division)
|
|
|
What is the scientific name for normal cell division?
|
Mitosis
|
|
|
What is a chromosome?
|
Where DNA is stored in
|
|
|
Explain the stages of Mitosis
|
1. Prophase - the chromosomes double and scrunch up
2. Metaphase - the chromosomes and their copies line up to separate sides of the nucleus 3. Anaphase - the chromosomes and their copies move to the separate sides of the nucleus 4. Telephase - the cell splits in 2 |

2 of the same gene (TT)
|
|
|
What is heterozygous?
|
2 different genes (Tt)

|
|
|
What is Genotype?
|
