In panel a (see 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 isA. CCCB. UACC. CAC The images depict stages in protein synthesis, specifically translation at the ribosome.**Image C**:- This diagram shows a ribosome (illustrated in green) bound to a strand of messenger RNA (mRNA). - The sequence of mRNA bases includes "AUG-CUG-CUC-AAA-GGG."- Transfer RNA (tRNA) molecules, depicted in blue, are shown aligned with the mRNA sequence.- Three amino acids, methionine (met), valine (val), and leucine (leu), are attached to the top of the tRNA molecules, linked in a growing polypeptide chain.**Image D**:- Similar to Image C, this diagram shows the ribosome continuing the translation process.- The mRNA sequence is the same: "AUG-CUG-CUC-AAA-GGG."- In this stage, four amino acids—methionine (met), valine (val), leucine (leu), and glycine (gly)—are attached as the polypeptide grows. These images illustrate the elongation phase of translation, where tRNA brings amino acids to the ribosome, matching codons on the mRNA to form a polypeptide chain. The image consists of two labeled diagrams (A and B) illustrating the process of protein synthesis in a ribosome through the translation of mRNA.**Diagram A Explanation:**- A section of ribosomal machinery, represented by a large light green shape, is shown interacting with an mRNA strand depicted as a gray line with black letters.- The ribosome is binding to the mRNA, which contains a series of codons (group of three nucleotides - AUG, CUG, etc.).- Attached to the ribosome is a transfer RNA (tRNA) molecule, depicted in blue, with an attached amino acid labeled "met" (methionine), positioned opposite the first mRNA codon, "AUG".- The diagram is annotated to show the different components: "amino acid", "tRNA", "ribosome", and "mRNA".**Diagram B Explanation:**- This phase expands upon Diagram A, showing a similar ribosomal setup.- Here, a second tRNA is visible, also portrayed in blue, carrying an amino acid labeled "val" (valine) in addition to the previous "met" amino acid.- The tRNAs align with their respective codons on the mRNA strand, which now show additional codons being read.- The ongoing process illustrates how amino acids are added sequentially to form a growing polypeptide chain.These diagrams represent the elongation stage of protein synthesis, where tRNA molecules match their anticodons with mRNA codons to add specific amino acids, building the chain corresponding to the genetic instructions within the mRNA.
