AIIMS 2018 Botany Transcription MCQ Question

Ribosomal RNA (rRNA) is synthesized from DNA and plays a crucial role in the assembly of ribosomes, which are the cellular machinery for protein synthesis. While rRNA itself does not synthesize other types of RNA, it is essential for the translation process where messenger RNA (mRNA) and transfer RNA (tRNA) interact to produce proteins. In contrast, tRNA and mRNA are specific types of RNA that serve distinct functions: tRNA carries amino acids to the ribosome, and mRNA serves as the template for protein synthesis, but neither can synthesize all types of RNA. DNA, while it serves as the template for the synthesis of all RNA types through transcription, is not itself a type of RNA.
