Terms and Definitions

• Degenerative Code - This means that some amino acids are coded for by more than one codon
• Non-overlapping - Specific 'start' codons ensure that ribosomes 'read' the mRNA in the correct way.
• Introns - Reigons of non-coding DNA, removed from mRNA before translation
• Semi-conservative replication - When only half/one strand of the DNA is replicated. This produces exact copies of the origional DNA.
• Gene - A length of DNA that codes for a single protein.
