- A certain mRNA strand has the following nucleotide sequence: 5AUGACGUAUAACUUU3 What is the anticodon for each codon? What is the amino acid sequence of the polypeptide? (Use Figure 13-5 to help answer this question.) Figure 13-5 The genetic code The genetic code specifies all possible combinations of the three bases that compose codons in mRNA. Of the 64 possible codons, 61 specify amino acids (see Figure 3-17 for an explanation of abbreviations). The codon AUG specifies the amino acid methionine and also signals the ribosome to initiate translation (start). Three codonsUAA, UGA, and UAGdo not specify amino acids; they terminate polypeptide synthesis (stop).arrow_forwardLook up a standard genetic code table, how many codons will be recognized by tRNA charged by lysyl-tRNA synthetase, then explain the degeneracy of genetic code observed by including the Wobble hypothesis.

It is carbon-based and its genetic material is similar to Earth DNA except that it uses 6 different nucleotide bases instead of 4. Its proteins are also similar to those on Earth, but there are 60 different amino acids instead of 20.
