Complementary sequences

DNA hybridization -- a technique for selectively binding specific segments of single-stranded (ss) DNA or RNA by base pairing to complementary sequences on ssDNA molecules that are trapped on a nitrocellulose filter.

Base-pairing between overhangs with complementary sequences enables two fragments to join or "to be spliced," which they tend to do spontaneously in a test tube.

A region of single-stranded DNA or RNA that can form base pairs between complementary sequences. For example the sequence 5'...GACGTGNNNNNCTGCAC...
Full article >>>

A class of RNA having structures with triplet nucleotide sequences that are complementary sequences to the triplet nucleotide coding sequences of mRNA.

perhaps by binding to complementary sequences on DNA or
perhaps by binding to the nascent RNA transcript as it is being formed.

DNA hybridization The formation of hybrid DNA molecules that contain a strand of DNA from two different species. The number of complementary sequences in common in the two strands is an indication of the degree of relatedness of the species.

Hairpin: A helical (duplex) region formed by base pairing between adjacent (inverted) complementary sequences within a single strand of RNA or DNA.
Full article >>>

A single-stranded DNA that has been radioactively labeled and is used to identify complementary sequences in genes or DNA fragments of interest. (See Multilocus probe.) Promoter.
