Question

In this picture, a tRNA is already bound to the initiator codon at the start of the mRNA strand. The anticodon sequence on this tRNA that complements the mRNA codon is

A. CCC
B. UAC
C. CAC
The image depicts the process of translation in protein synthesis, where mRNA is being translated into a polypeptide chain by the ribosome. Key components in the diagram are:

1. **Ribosome**: Represented as a large, green structure, the ribosome is the molecular machine that facilitates the translation of mRNA into a protein.

2. **mRNA (messenger RNA)**: Displayed as a linear sequence of nucleotides. The sequence shown here is "AUG GUG UAG GCA UCC CAA...". The ribosome reads this mRNA strand in sets of three nucleotides, known as codons.

3. **tRNA (transfer RNA)**: Illustrated as a blue structure, it carries the amino acid methionine (met) and matches its anticodon (UAC) with the start codon (AUG) on the mRNA.

4. **Amino Acid**: Methionine is specified as the first amino acid in the sequence, serving as the starting point for the polypeptide chain.

Overall, this diagram provides a visual representation of how the genetic code in mRNA is translated into a functional protein by the ribosome, with the involvement of tRNA molecules that bring specific amino acids corresponding to the codons on the mRNA strand.
