1
New cards
What are the 3 main stages of cell cycle
Growth, Mitosis, Division
2
New cards
When is mitosis/cell cycle used for
Growth, Repair, Development
3
New cards
What is the process of the cell cycle
No* of sub-cellular substances are increased
Chromosomes duplicates
Mitosis
Cell membrane and cytoplasm pull apart
Two identical daughter cells are formed
4
New cards
When the cell prepares for division what does the dna do
It condenses into chromosomes
5
New cards
What are chromosomes
thread-like structure made up of DNA
6
New cards
How many pairs of chromosomes do humans have
23 pairs
7
New cards
How do DNA duplicate
Each chromosome is duplicated
Duplicate is still attached to original chromosome
8
New cards
Why is the cell cycle needed for growth
We need more cells as we grow
9
New cards
Why is the cell cycle needed for repair
We need to replace cells that we lose every day
10
New cards
Why is the cell cycle needed for development
We need new cell types as we develop new tissues
11
New cards
What is the cell cycle
Series of steps that take place as a cell grows and then divides
12
New cards
What is the process of mitosis
DNA condenses to form chromosomes
Chromosomes lines up in centre of cell to prepare for division
Cell fibres pull the arms of each chromosome to either opposite of cell
13
New cards
Are the cells created by mitosis genetically identical or genetically different
Genetically identical
