DNA Nucleotides Base Pairs (A-T//C-G) Adenine-Thymine Ctyosine-Guanine Couple or Friendship Necklaces

Nucleotides make up DNA. Each nucleotide is composed of one of four nitrogen-containing nucleobases—either cytosine (C), guanine (G), adenine (A), or thymine (T)—and a sugar called deoxyribose and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. The nitrogenous bases of the two separate polynucleotide strands are bound together (according to base pairing rules (A with T, and C with G) with hydrogen bonds to make double-stranded DNA.

Choose from the base pairings of Adenine-Thymine(A-T) or Cytosine-Guanine(C-G).
Great as couple/lover necklaces or friendship/best friend necklaces, as they these base pairs only pair up with each other, but never with another (A-G and T-C will never be a combination).

Necklaces are 17 inches, adjustable up to 19 inches.
Nucleotide charm is 1 inch.
