WebMar 13, 2024 · The tRNAs are the carriers of specific amino acids encoded in the mRNA. The main difference between mRNA and tRNA is that mRNA serves as the messenger … WebThe following points highlight the top three types of RNA. The types of RNA are: 1. Transfer RNA (tRNA) 2. Messenger RNA (mRNA) and 3. Ribosomal RNA (rRNA). RNA Type # 1. Transfer RNA (tRNA): It delivers amino acids to ribosome and decodes the information of mRNA. Each nucleotide triplet codon on mRNA represents an amino acid. WebThe first step in their processing is the digestion of the RNA to release individual pre-tRNAs. In archaea and eukaryotes, each pre-tRNA is transcribed as a separate transcript. The processing to convert the pre-tRNA to a mature tRNA involves five steps. 1. The 5' end of the pre-tRNA, called the 5' leader sequence, is cleaved off. terri wangard author
