3 Types of RNA

mRNA Messenger RNA Facts: Function: uses DNA as template single stranded U replaces T largest RNA molecule Function: mRNA is used to carry the genetic code from the nucleus to the ribosomes

tRNA Transfer RNA Facts: On one end of the tRNA a specific amino acid attaches. On the other end is a sequence of three base pairs called the anticodon, the complement of the codon on the mRNA. Function: tRNA bonds to amino acids and it is used in the synthesis of proteins

Ribosome

rRNA Ribosomal RNA Facts: Function: A component of ribosomes The small subunit of a ribosome contains an rRNA strand (1542 nucleotides long) The larger subunit contains two strands of rRNA (one 2904 nucleotides in length and the other 120). Function: A component of ribosomes

3 Types of RNA Messenger RNA = mRNA Transfer RNA = tRNA Ribosomal RNA = rRNA
