What are Genes/where are they found?
Found: in the cell's nucleus. Determine all inherited characteristics of an organism
1 of 21
How are genes linked together?
In a long string called chromosomes
2 of 21
What is DNA?
chemical molecule that makes up genes, coded information for the production of different proteins

What is a genome?
An organism's complete set of genes
4 of 21
What are gamates?
Sex Cells
5 of 21
What is a mutation?
A change in the structure of the gene, occurs naturally or by ionising radiation

What is Meiosis
Division of cells that form sex cells, sperm or egg

What is Haploid?
Cell with half number of chromosomes
8 of 21
