Question

1) This model shows the process of protein synthesis including transcription and translation. What is the best explanation for what is occurring at the arrow (translation)?

es
A) tRNA is read and its code used to place amino acids to make a protein
B) mRNA is read and its code used to place nucleotides to form a protein.
The codon on the mRNA pairs with the anticodon on the tRNA which transfers amino acids into the proper sequence to form a protein.
D) The anticodon on the mRNA pairs with the codon on the tRNA which transfers amino acids into the proper sequence to form a protein.

Answer 1

During translation, the codon on mRNA pairs with the anticodon on tRNA, transferring amino acids into the correct sequence to form a protein.

Step-by-step explanation:

The best explanation for what is occurring at the arrow indicating the process of translation in protein synthesis is that the codon on the mRNA is pairing with the anticodon on the tRNA, which transfers amino acids into the proper sequence to form a protein.

This process involves tRNA molecules that physically 'read' the mRNA codons and bring the corresponding amino acids to the ribosome, attaching each new amino acid to the polypeptide chain. As the tRNA matches its anticodon with the codon on the mRNA strand, it contributes its specific amino acid cargo to the growing protein chain. This vital part of translation ensures that the genetic code in the mRNA is translated accurately into a sequence of amino acids that will fold into a functional protein.
