(Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base pair, named after James Watson and Francis Crick, who first proposed the double helix structure of ...

Within the ribosome, the mRNA and aminoacyl-tRNA complexes are held together closely, which facilitates base-pairing. The rRNA catalyzes the attachment of each new amino acid to the growing chain.

The mRNA then travels to the ribosome, where translation occurs ... The rules for wobble base pairing are as follows: The first two bases of a codon always form standard Watson-Crick base pairs with ...

Although these molecules are only 21 to 25 base pairs in length ... This RNA-containing complex can then inhibit transcription of an mRNA molecule that has a sequence complementary to its RNA ...

U base pairs with A. Because the opposite base bonds with the exposed DNA bases, the strand of mRNA is an opposite copy of the DNA strand (except that U replaces T). We call this a complementary copy.

"This method reads 100 to 150 base pairs at a time and compares each to ... The findings included uncovering new mRNA sequences from all 50 target genes that had not been found by previous ...
