Small subunit ribosomal ribonucleic acid is the smaller of the two major RNA components of the ribosome.
Associated with a number of ribosomal proteins, the SSU rRNA forms the small subunit of the ribosome. It is encoded by SSU-rDNA.
Use in phylogenetics
SSU rRNA sequences are widely used for determining evolutionary relationships among organisms, since they are of ancient origin and are found in all known forms of life. == See also ==
