Table 6-1Principal Types of RNAs Produced in Cells

mRNAsmessenger RNAs, code for proteins
rRNAsribosomal RNAs, form the basic structure of the ribosome and catalyze protein synthesis
tRNAstransfer RNAs, central to protein synthesis as adaptors between mRNA and amino acids
snRNAssmall nuclear RNAs, function in a variety of nuclear processes, including the splicing of pre-mRNA
snoRNAssmall nucleolar RNAs, used to process and chemically modify rRNAs
Other noncoding RNAsfunction in diverse cellular processes, including telomere synthesis, X-chromosome inactivation, and the transport of proteins into the ER
