Question

Charging of Transfer RNAs. Which of the following is the actual event that translates the language of nucleic acids (the sequence of bases, A, T (U), C, and G) to the language of proteins (determining which amino acid will be added to the polypeptide)?

A) Transcription.
B) Translation.
C) Replication.
D) Splicing.

Answer 1

The actual event that translates the language of nucleic acids to the language of proteins is Translation. During translation, the mRNA code is read in the ribosome and matched with the appropriate transfer RNA (tRNA) molecules, which carry specific amino acids that build the polypeptide chain.

Step-by-step explanation:

The actual event that translates the language of nucleic acids (the sequence of bases, A, T (U), C, and G) to the language of proteins (determining which amino acid will be added to the polypeptide) is Translation.

During translation, the mRNA code is read in the ribosome. Sets of three bases, called codons, are read and matched with the appropriate transfer RNA (tRNA) molecules. Each tRNA molecule carries a specific amino acid that matches the codon on the mRNA. The amino acids are linked together, forming a polypeptide chain which eventually becomes a protein.
