Final answer:

The false statement about rRNA is that it is involved in translation initiation. rRNA is transcribed from DNA and is essential for the elongation step in translation, not the initiation.

Step-by-step explanation:

The false statement about ribosomal RNA (rRNA) is d. rRNA is involved in translation initiation.rRNA is synthesized in the nucleolus and is a core structural component of ribosomes, crucial for their function in protein synthesis. It is transcribed from DNA by RNA polymerase I, except for the 5S rRNA which is transcribed by RNA polymerase III. rRNA forms the catalytic core of ribosomes and is involved in translation, particularly during the elongation stage where it catalyzes the formation of peptide bonds, rather than initiation specifically.
