(f) the nature of the genetic code

What is the genetic code

The specific sequence of amino acids that the dna codes for to make a protein

Describe the triplet code

Instructions of dna is contained i a sequence of 3 bases which is called a codon. This codon is a triplet code

The genetic code is the triplet code as 1 code codes for one amino acid

What is a gene

A section of dna that contains the complete sequence of bases to code for an entire protein

(In other words a complete codon sequence)

How many different codons are possible

64

4×4×4

thee are 4 different bases and a sequence of 3 bases is one codon.

What are the different codons

Start codon = signals the start of a sequence for a protein

3 stop codons that signal the end of the sequence and dont code fo an amino acid

What happens when a start codon is in the middle of a gene

It codes for the amino acid methionine

What is the importance of a single codon starting the sequence

It makes sure the dna is being coded in gram and there is no overlap in the genetic code.

What is a degenerate code

Because there are only 20 different amino acids and there are 64 different codons possible there are more codons than amino acid ]

So degenerate code is the different combinations of bases that can code for the same amino acid.
