Given the <u>non</u>-<u>coding </u>nature of the rRNA present in ribosomes, we can conclude that <u>option a</u><u> is false</u>.
Ribosomes are two-part structures in a cell that are in charge of the translation process, in which a strand of mRNA that codes for a certain protein is read and the protein is produced. Ribosomes are comprised of:
- A large subunit
- A small subunit
- Various types of rRNA
<u>Option b</u> is correct given that translation is the very function of the ribosomes. To do this they bind the 5' end of the mRNA to the <em><u>small </u></em>subunit. Then move along the mRNA strand in small "steps" as they read the code in the 3' direction and use the enzymes present in the <em><u>larger </u></em>subunit to fuse together the corresponding amino acids. Therefore, <u>options c, d, and e can also be confirmed as true.</u>
The option which <u>is false and therefore does not pertain to ribosomes during protein synthesis is </u><u>option a</u> which states that "<em>they contain codons within their rRNA molecules</em>". The rRNA present serves structural purposes among others in the ribosome but are non-coding. Given that any coding at this level is given by codons, we can conclude that they do not have codons.
