What nonapeptide is coded for by the following fragment of mRNA?
5’—AAA—GUU—GGC—UAC—CCC—GGA—AUG—GUG—GUC—3’
Interpretation:
Nonapeptide which is coded for by the given strand of mRNA.
Concept introduction:
RNA is the abbreviation term of “Ribonucleic Acid”. It is a complex molecule found in all living things.
RNA helps to make proteins.
Important RNAs such as messenger RNA (mRNA),
Codons are the sequence of three bases in mRNA that specifies the amino acid to be incorporated into a protein.
Some amino acids and their corresponding mRNA codons are listed below,
Anticodons are the matching sequence on the
A base is nitrogen containing heterocyclic compound which is found in DNA and RNA.
There are mainly four nitrogen bases in RNA.
- (1) Adenine
- (2) Guanine
- (3) Cytosine
- (4) Uracil
In RNA, Adenine always makes a double bond with uracil (
