- DNA
- Encodes the amino acids in a protein
- Unique to everyone
- Tightly wound in to chromosomes
- Humans have 23 pairs of chromosome
- Two copies of every gene
- Alleles are different versions of genes
- Two copies of every gene
- Chromosome have hundreds of genes
- Genes are in chromosome
- Genes are short sections of DNA
- Chromosome are found in the nucleus of the cell
- Humans have 23 pairs of chromosome
- DNA has a double helix structure
- MITOSIS 1,1*,2
- Human cell with 23 pairs of chromosomes
- All chromosomes are copied
- Splits in to 2 genetically identical cells
- Splits in to 2 genetically identical cells
- Correct number of chromosomes per daughter cell
- All chromosomes are copied
- This happens during growth replacement, repair of cells and in asexual reproduction
- Human cell with 23 pairs of chromosomes
- MITOSIS 1,1*,2
- Gametes are sperm(testes) and egg cells(ovaries)
- They are NOT paired they are singular.
- MEIOSIS 1,1*, 2,4
- Human cell with 23 pairs of chromosomes
- All chromosomes are copied
- Splits in to 2 genetically identical cells
- Splits in to 2 cells with only single chromosomes called gametes
- Splits in to 2 cells with only single chromosomes called gametes
- Splits in to 2 genetically identical cells
- Splits in to 2 cells with only single chromosomes called gametes
- Splits in to 2 cells with only single chromosomes called gametes
- Splits in to 2 genetically identical cells
- All chromosomes are copied
- Human cell with 23 pairs of chromosomes
- Fertilisation is where a sperm joins with an egg.
- SPERM 23 single chromosomes
- Fertilise and become 23 pairs of chromosomes
- EGG 23 single chromosomes
- SPERM 23 single chromosomes
