Nature Of The Genetic Code Flashcards
1
Q
What is a gene?
A
Instructions to build a polypeptide
2
Q
What is the genetic code?
A
The sequence of bases coding for a sequence of amino acids
3
Q
What are the 3 types of RNA?
A
- Messenger =mRNA
- Transfer= tRNA
- Ribosomal= rRNA
4
Q
What is the triplet code?
A
A sequence of 3 bases which code for each amino acid
5
Q
What does degenerate mean?
A
More then one codon can code for each amino acid
6
Q
What does non-overlapping mean?
A
Each base sequence is only read once
7
Q
What does universal mean?
A
The same codon codes for the same amino acid in all organisms
8
Q
How do you find the amino acid which the codon does for?
A
Look at the first letter on the grid, then second, then third and it’ll correspond to the correct amino acid
