An investigator studying protein synthesis in human stem cells isolates tRNA molecules bound to mRNA molecules. The isolated tRNA molecules have inosine in the 5' position of the anticodon; of these, some are bound to adenine, some to cytosine, and some to uracil at the 3' position of the mRNA codon. Which of the following properties of the genetic code is best illustrated by this finding?
- A)Specificity of the start codon
- B)Specificity of stop codons
- C)DegeneracyGABARITO
- D)Unambiguity
- E)Non-overlapping
Explicação
Degeneracy of the genetic code refers to the redundancy of codon base pairing, whereby multiple codons can specify a single amino acid. During translation, some tRNA molecules can recognize multiple codons because of flexibility at the wobble position — the pa... Ver explicação completa e trilha adaptativa →
