Question

# A researcher identifies the nucleotide sequence AAC in a long strand of RNA inside a nucleus. In the genetic code, AAC codes for the amino acid asparagine. When that RNA becomes involved in protein synthesis, will asparagine necessarily appear in the protein? Use specific content to support your argument.

Solution

Verified

A cell interprets the genetic code through codons in the mRNA, which are sequences of three nucleotides in a row. If we know that one part of the mRNA is AAC, that doesn't necessarily have to be a codon because we don't know the beginning of the nucleotide sequence and the end of the previous codon. There is a higher probability that these three nucleotides are parts of two codons. Therefore, asparagine that is coded by AAC doesn't have to appear in the polypeptide chain.
