Genetic Code Flashcards
(8 cards)
1
Q
How are mRNA nucleotides arranged?
A
They are arranged in 3 nucleotide groups called codons.
2
Q
Degeneracy
A
Multiple codons can code for the same amino acid.
3
Q
How many chain terminators are there and do they code for amino acids?
A
3 and no they do not code for amino acids.
4
Q
How many chain initiators are there and does it code for an amino acid?
A
1 and yes it does code for an amino acid.
5
Q
How many codons actually code for amino acids and what is the significance of this?
A
61 codons code for the 20 amino acids. There are enough codons to confer degeneracy to the mRNA.
6
Q
What direction is the protein produced?
A
N-terminal to C-terminal
6
Q
What direction is the reading frame read?
A
5’ to 3’
7
Q
What constitutes the open reading frame?
A
From the initiation codon to the stop codon.
