Nucleic acid hybridization Nucleic acid hybridization In molecular biology, hybridization (or hybridisation) is a phenomenon in which single-stranded deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) molecules anneal to complementary DNA or RNA. Though a double-stranded DNA sequence is generally stable under physiological conditions, changing these conditions in the laboratory (generally by raising the surrounding temperature) will cause the molecules to separate into single strands. These strands are complementary to each other but may also be complementary to other sequences present in their surroundings. Lowering the surrounding temperature allows the single-stranded molecules to anneal or “hybridize” to each other. DNA replication and transcription of
Docosapentaenoic acid omega-3 fats in humans, such as in inflammation mechanisms. Docosapentaenoic acid Docosapentaenoic acid (DPA) designates any straight chain 22:5 fatty acid, that is a straight chain open chain type of polyunsaturated fatty acid (PUFA) which contains 22 carbons and 5 double bonds. DPA is primarily used to designate two isomers, "all"-"cis"-4,7,10,13,16-docosapentaenoic acid (i.e. 4"Z",7"Z",10"Z",13"Z",16"Z"-docosapentaenoic acid) and "all"-"cis"-7,10,13,16,19-docosapentaenoic acid (i.e. 7"Z",10"Z",13"Z",16"Z",19"Z"-docosapentaenoic acid). They are also commonly termed n-6 DPA and n-3 DPA, respectively; these designations describes the position of the double bond being 6 or 3 carbons closest to the (omega) carbon at the methyl end of the molecule and is
