How many of the 64 possible triplets in the genetic code are stop codons?
A. 1
B. 3
C. 5
D. 7
E. 61
Homework Answers
In 64 possible triplets, there are found three stop codons and sixty one codons which codes for amino acid.
These three stop codons are: UAA, UAG and UGA.
That's why right option is B (3).

The genetic code is read in groups of three (3) nucleotides called codons. Some mutations are silent because they have no effect on the phenotype. How is that possible? Since there was a mutation in one of the codons, that gene will not be expressed. o It is not possible, mutations are always expressed and always have an effect The mutation changed the codon but the new codon codes for the same amino acid The ribosome knows there was a...

The genetic code is considered degenerate because most amino acids are encoded by at least two different codons. Some researchers have hypothesized that during evolution the genetic code has been optimized for its intended use in different organisms. Reseachers can study this by examining the relationship between the frequency with which an amino acid appears in all the proteins in an organism and the total number of codons for an amino acid. An optimized organism would use amino acids in...
