- Chromosomes and Mitosis
- contain genetic information
- most cells in your body have a nucleus
- coiled up lengths of DNA molecules
- coiled up lengths of DNA molecules
- carry large numbers of genes
- control the development of different characteristic traits
- hair colour
- control the development of different characteristic traits
- body cells have two copies of each chromosome
- one from the 'mother' and one from the 'father'
- we have 23 pairs of chromosomes
- the 23rd pair
- **
- female
- XY
- male
- **
- the 23rd pair
- the cell cycle
- the cell cycle
- divide to produce new cells
- the stage where the cell divides
- mitosis
- grow and replace cells that have been damaged
- two new cells identical to the original cell
- Interphase - the DNA replicates to prepare for mitosis
- Prophase
- Metaphase
- Anaphase
- Telophase
- Cytokenesis
- Telophase
- Anaphase
- Metaphase
- Prophase
- Before the cell divides the cell has to grow and increase the amount of subcellular structures such as mitochondria and ribosomes
- duplicates DNA
- DNA is copied and forms X-shaped chromosomes
- each 'arm' is an exact duplicate of the other
