WebRNA Types. There are various types of RNA, out which most well-known and most commonly studied in the human body are : tRNA – Transfer RNA; The transfer RNA is held responsible for choosing the correct protein or the amino acids required by the body in-turn helping the ribosomes. It is located at the endpoints of each amino acid. WebEach tRNA contains a sequences of three bases specific to one of the 20 amino acids – a codon. Given each amino acid is coded by a sequence of three bases, you might assume there would be 64 possible combinations (of the four possible bases). portsmouth 5g
