Diskussion:Shine-Dalgarno-sekvensen

Shine-Dalgarno-sequence a ribonucleotide sequence for the formation of the preinitiation complex between a 30S ribosomal subunit and an mRNA molecule. It is a seven-nucleotide, pyrimidinerich sequence near the 3′ terminus of 16S (prokaryotic) or 18S 613 sham operated Shine–Dalgarno sequence eukaryote ribosomal RNA, found in many organisms, that forms base pairs with a complementary three- to seven-nucleotide, purinerich sequence (the Shine–Dalgarno sequence) preceding the initiation codon in many mRNA molecules, thereby allowing the initiating ribosomal subunit to bind the mRNA so as to discriminate between AUG or GUG (i.e. initiation) triplets and to select the one at the beginning of a cistron. [After John Shine (1946– ) and Lynn Dalgarno (1935– ).]
