Question

how can a single mutation of one nitrogen base in a dna strand have no impact on the production of the protein from the dna strand?
the mrna translated to the same amino acid.
the dna transcribed to the same amino acid.
the trna corrected the error during transcription.
the mrna corrected the error during translation.

Explanation:

DNA is first transcribed into mRNA, and then mRNA is translated into proteins. The genetic code is degenerate, meaning multiple codons (sequences of three - nucleotide bases in mRNA) can code for the same amino - acid. So, a single - base mutation in DNA may result in an mRNA codon that still codes for the same amino - acid, having no impact on protein production. tRNA and mRNA do not correct errors in this context. DNA does not directly translate to amino - acids; it is through mRNA.

Answer:

The mRNA translated to the same amino acid.
