Molecular structure of DNA

dna structure  Chromosomes have proteins called histones that bind to DNA DNA has two strands that twist into the shape of a spiral ladder called a helix DNA The monomers of DNA are called nucleotides Nucleotides have three components: a base, a sugar and a phosphate residue The four bases are adenine

DNA consists of 2 polynucleotide chains or strands, wound around each other such that they resemble a twisted ladder This structure is referred to as the The structure of DNA is that of a double helix Similar to a spiral staircase, DNA is twisted and coiled so that it can be packed into our
