Types of RNA There are 3 types of RNA: Transfer RNA (tRNA) Ribosomal RNA (rRNA) Messenger RNA (mRNA)

Transfer RNA (tRNA) Makes up 15% of the total RNA in the cell Has two active sites: one for the attachment of an amino acid and the anticodon loop, which recognizes mRNA codons Although there are only 20 amino acids, there are at least 56 different types of RNA, each recognizing different anticodon triplets Made in the nucleus

Ribosomal RNA (rRNA) Makes up 80% of the total RNA in the cell Along with proteins, rRNA makes up the ribosomes Made in the nucleolus

Messenger RNA Direct carrier of the genetic information in DNA It is complementary to a DNA strand In eukaryotes, it is made up of introns (non-coding regions) and exons (coding regions) Made in the nucleus
