Necessary Coexistence, Inseparable Pairs; Unity is Plural
or inherent complementarity of Universe: Necessary co-existence, inseparable pairs. Fuller emphasizes that Universe consists of complementary teams, such as concave-convex, tension-compression, positive-negative, and male-female, and concludes that "unity is inherently plural."
The antiparallel pairing of nucleotides in double-stranded DNA, double-stranded RNA, or DNA-RNA duplexes.
The reverse structural correspondence of one molecule to another, such as an antibody to an antigen, an enzyme to a substrate, or the bases in a base pair.
Necessary co-existence, inseparable pairs. The universe is inherently complementary, such as in concave-convex, positive-negative, male-female. "Unity is inherently plural". (Buckminster Fuller)
specific base pairing of nucleotide bases in nucleic acids.
Within the DNA two specific bases join to become a pair by means of hydrogen bridges. Adenine always connects with thymine and cytosine with guanine, they are complementary. Because of this rule the two strands of the DNA run "anti-parallel" to each other: 5'-TGCA-3' joins with 3'ACGT-5'.
The pairing off of nucleotides, between a strand of RNA and a strand of DNA, in the following manner: Adenines (A) with uracils (U), and the cytosines (C) with the guanines (G).
The sequence-specific or shape-specific recognition that occurs when two or more molecules bind together. DNA forms double stranded helixes because the complementary orientation of the bases in each strand facilitate the formation of the hydrogen bonds which hold the strands together.
In genetics, a double-stranded DNA strand consists of two complementary strands of base pairs, which are non-covalently connected via two or three hydrogen bonds.
