Final answer:
Messenger RNA (mRNA) and ribosomal RNA (rRNA) are the two most clinically important types of RNA. mRNA carries genetic instructions from DNA to the cytoplasm, while rRNA forms ribosomes where proteins are synthesized.
Step-by-step explanation:
The two most clinically important types of RNA mentioned in class are messenger RNA (mRNA) and ribosomal RNA (rRNA).
Messenger RNA (mRNA) copies the genetic instructions from DNA and carries them to the cytoplasm, where they are used as a template for protein synthesis.
It acts as a messenger between DNA and the ribosomes, which are the organelles where proteins are assembled.
Ribosomal RNA (rRNA) combines with proteins to form ribosomes, which are responsible for protein synthesis. Ribosomes are found in large numbers in cells and are the site where mRNA and tRNA interact to synthesize proteins.
