3.16



• 1 chromosome = 1000 genes
• if you magnify 1 gene loci you find a double helix (genes are parallel)
• when magnifying it even more you can see that there is what we call a base holding them together
• four different base types: Adenine (A) Thymine (T) Cytosine (C) Guanine (G)
• base types are always found in pairs T-A G-C T-G
• one side of the chromosomes has a ACTGAACCAG order to the bases which we call a gene
