DNA necklace H | gold vermeil product_circular DNA The A chain (21 residues)

The A chain (21 residues) and B chain (30 residues) are linked by two interchain disulfide bonds plus one intrachain disulfide in the A chain

molecular biologists and geneticists

The hairpin RNA that lets a single sequence silence a chosen gene with reasonable specificity

Synthetic chemists use it as the simplest molecular knot to build

DNA necklace H | gold vermeil product_circular DNA The A chain (21 residues)DNA necklace H 18k gold vermeil The double helix, in horizontal orientation, in 18k gold vermeil. Both backbones spiral at full width with the major and minor grooves visible. The form that makes the helix easiest to read. The Science Behind the DNA Helix The major groove and minor groove are the two channels running along the helix where the backbone strands are farther apart or closer together. The major groove is wide enough for proteins to read
