Prokaryotic small ribosomal subunit

WebIn prokaryotes, the ribosome binding site (RBS), which promotes efficient and accurate translation of mRNA, is called the Shine-Dalgarno sequence after the scientists that first described it. This purine-rich sequence of 5′ UTR is complementary to the UCCU core sequence of the 3′-end of 16S rRNA (located within the 30S small ribosomal subunit). The ribosome is a complex cellular machine. It is largely made up of specialized RNA known as ribosomal RNA (rRNA) as well as dozens of distinct proteins (the exact number varies slightly between species). The ribosomal proteins and rRNAs are arranged into two distinct ribosomal pieces of different sizes, known generally as the large and small subunit of the ribosome. Ribosomes consist o…

WebThe eukaryotic small ribosomal subunit(40S) is the smaller subunit of the eukaryotic 80S ribosomes, with the other major component being the large ribosomal subunit (60S). The "40S" and "60S" names originate from the convention that ribosomal particles are denoted according to their sedimentation coefficientsin Svedberg units.
