DNA Structure

dna structure  DNA was discovered The structure of DNA Watson Image courtesy of James D Watson But there's no denying that the discovery of DNA was a tremendous 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

Generally speaking, the fundamental DNA structure can be simply perceived as a double helical structure: two single DNA strands twisted around each other in the DNA's unique structure enables the molecule to copy itself during cell division When a cell prepares to divide, the DNA helix splits down

DNA is made up of six smaller molecules As mentioned, DNA is a polymer of nucleotides joined together The backbone of DNA is made of alternating phosphate groups and sugars, represented by the green
