Worked Solution & Example Answer:The diagram below shows part of the translation process of protein synthesis - VCE - SSCE Biology - Question 19 - 2008 - Paper 1

Step 1

A. messenger RNA.

Answer

Messenger RNA (mRNA) is the template that carries the genetic information from DNA to the ribosome, where proteins are synthesized. In the context of translation, mRNA provides the sequence of codons that determine the order of amino acids in a protein.

Step 2

B. ribosomal RNA.

Answer

Ribosomal RNA (rRNA) is a structural and functional component of ribosomes. It facilitates the assembly of amino acids into protein chains during translation. Given the context of the diagram where Structure X appears to represent a site integral to translation, this option is relevant.

Step 3

C. transfer RNA.

Answer

Transfer RNA (tRNA) plays a critical role in translation by bringing the appropriate amino acids to the ribosome in accordance with the codon sequence on the mRNA. Each tRNA molecule is specific to one amino acid.

Step 4

D. nuclear DNA.

Answer

Nuclear DNA is the genetic material that contains the instructions for synthesizing proteins, but it is not directly involved in the translation process illustrated in the diagram.
