Q.What are the types of RNA? Mention the role of each class of RNA.

Step 1. mRNA (messenger RNA) is a linear single strand that carries the genetic information copied from DNA, specifying the exact order in which amino acids must be joined to build a particular polypeptide; the stretch of mRNA coding for one polypeptide is called a cistron.

Step 2. rRNA (ribosomal RNA) makes up 50-60% of the mass of a ribosome and 80-90% of total cellular RNA; it forms the structural framework of the ribosome, the organelle on which protein synthesis actually takes place. …

List the three RNA types and state each one's specific functiona …

• Swapping the roles of rRNA and tRNA — rRNA builds the ribosome structure, tRNA ferries amino acids; they are easy to confuse by name alone. …
