Base pairing

Base pairing

(Science: molecular biology) The specific hydrogen bonding between purines and pyrimidines in double stranded nucleic acids.

in dna the pairs are adenine and thymine and guanine and cytosine, while in rna they are adenine and uracil and guanine and cytosine.

base pairing leads to the formation of a dna double helix from two complementary single strands.

Re: How to knock down a gene?

"Knockdown" implies an oligo-based method. This could be actually introducing an oligo into cells, such as one ... transcript expressed then interacts with the target mRNA by complementary base pairing (a sense-antisense interaction). The specific mechanism of silencing varies ...
