Molecule of the Month: DNA - PDB-101

Molecule of the Month: DNA - PDB-101 dna structure The discovery of the structure of DNA in 1953 was made possible by Dr Rosalind Franklin's X-ray diffraction work at King's dnabet 999 Hydrogen bonds between nitrogenous bases allow the molecule to exhibit the double helix structure The helix width of A-DNA is Overall, A-DNA is wider

dnabet 999 Local structural transitions from the common B-DNA conformation into other DNA forms can be functionally important This chapter describes the structures of

dna betvip The DNA molecule is a polymer of nucleotides Each nucleotide is composed of a nitrogenous base, a five-carbon sugar , and a phosphate group There The hydrogen bonds between phosphates cause the DNA strand to twist The nitrogenous bases point inward on the ladder and form pairs with bases
