Enlist the types of RNA. Discuss various structural features of each.
Answers
1) MRNA - Messenger RNA: Encodes amino acid sequence of a polypeptide.
2) TRNA - Transfer RNA: Brings amino acids to ribosomes during translation.
3) RRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.
4) SNRNA - Small nuclear RNA: With proteins, forms complexes that are used in RNA processing in eukaryotes. (Not found in prokaryotes.)
✔️There are 4 types of RNA, each encoded by its own type of gene.
✔️The genomic DNA contains all the information for the structure and function of an organism.
✔️In any cell, only some of the genes are expressed, that is, transcribed into RNA.
