Within the National 5 Biology course, you will need to know:
- Structure of DNA: double-stranded helix held by complementary base pairs.
- DNA carries the genetic information for making proteins.
- The four bases: adenine, cytosine, guanine and thymine (A, C, G and T) make up the genetic code.
- A is always paired with T and C is always paired with G.
- The base sequence determines amino acid sequence in proteins.
- A gene is a section of DNA which codes for a protein.
- Messenger RNA (mRNA) is a molecule which carries a complementary copy of the genetic code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.
