RNAs involved in protein biosynthesis

At the 3' end of every transfer RNA molecule, the chain ends with the sequence of bases C C A. Remember that the bases in RNA and DNA are attached to a backbone of alternating phosphate and sugar groups. At the very end of the chain is the -OH group on the 3' carbon of a ribose ring.

The messenger RNA now binds to a ribosome, where the messageis translated into a sequence of amino acids. The amino acidsthat are incorporated into the protein being synthesized arecarried by relatively small RNA molecules known as transferRNA, or tRNA. There are atleast 60 tRNAs, which differ slightly in their structures, ineach cell. At one end of each tRNA is a specific sequence ofthree nucleotides that can bind to the messenger RNA. At theother end is a specific amino acid. Thus, each three-nucleotidesegment of the messenger RNA molecule codes for the incorporationof a particular amino acid. The relationship between thetriplets, or codons, on the mRNA and the amino acids is shown inthe table below.

Proteins are assembled on ribosomes,
and ribosomes are made of
several dozen proteins as well as rRNA.
are produced by
copying part of the nucleotide sequence of DNA
complementary sequence in RNA
This process is called
, which is
to the DNA polymerase in
binds to DNA and separates the DNA strands.

For example, polypeptides (proteins) result from the linking of amino acids by peptide bonds and polysaccharides result from the linking of sugars by glycosidic bonds.
