Question

The function of transfer RNA (tRNA) is:

a) To bring a sequence of nucleotides from DNA to the ribosome
b) To bind RNA to the ribosome
c) To deliver amino acids to the ribosome
d) All of the above
e) None of the above

Answer 1

The function of transfer RNA (tRNA) is to deliver amino acids to the ribosome during the process of protein synthesis. Each tRNA molecule carries a specific amino acid and matches an anticodon with codons on mRNA to ensure the accurate assembly of proteins.

Step-by-step explanation:

The function of transfer RNA (tRNA) is to deliver amino acids to the ribosome during protein synthesis. This small RNA molecule plays a crucial role in translating the genetic code from mRNA into a specific amino acid sequence. Each tRNA molecule is modified to carry a specific amino acid and has an anticodon which pairs with the corresponding codon on the mRNA strand. This pairing ensures that amino acids are added in the correct order to build the polypeptide chain.

During the translation process, tRNA molecules bind to a codon of three nucleotides on the mRNA and are charged with the appropriate amino acid. The tRNA then transfers the amino acid to the growing polypeptide chain at the ribosome. This critical step ensures the accurate assembly of proteins, and any mutation in the tRNA can lead to global problems for the cell, affecting proper protein synthesis.
