If an mRNA is made up of 60 bases how many codons does it contain and how many amino acid does it code for?
A codon is exactly three bases long, so an mRNA strand with 60 bases would contain 20 codons. The first codon will encode for methionine (this is called the "start" codon) and the last codon will be a "stop" codon, which does not encode for an amino acid. Thus, an mRNA strand of 60 bases will code for 19 amino acids. Keep in mind, it is possible for a stop codon to be anywhere on the mRNA strand, and when a stop codon reaches the ribosome, translation must stop. For example, if an mRNA strand contained 30 codons, and the 15th were a stop codon, the mRNA would only code for 14 amino acids and then be done. The other 15 codons would go untranslated.
Can a codon contain two of the same nucleotide bases?
no
The genetic code is said to be universal because a codon represents the same?
The genetic code is said to be universal because a codon representsthe same amino acid in almost all organisms.
The genetic code is degenerate?
Each amino acid can be specified by more than one codon.
What about the degenracy of genetic code?
Type your answer here... the degenracy of code means there are more than one codons for one amino acid.The opposite of it ie.non-degeneracy of codon means ther is only one codon for one amino acid.
