Chapter Fifteen: The Genetic Code and Translation
... The tRNA molecules form base pairs with codons on the mRNA. The 3' end of the 16S rRNA within the small ribosomal subunit forms base pairs with Shine-Dalgarno sequence at the 5' end of the mRNA. Ribosomal RNAs on both the large and small subunit interact with tRNAs at both the “A” and the “P” sites. ...
