DNA explained: Structure, function, and impact on health

dna structure  Local structural transitions from the common B-DNA conformation into other DNA forms can be functionally important This chapter describes the structures of Summary DNA is a molecule found in most cells holding each person's unique genetic code It is responsible for coding proteins, which are essential to the

DNA is made of two dextrogyre helical chains or strands , coiled around an axis to form a double  DNA is made up of six smaller molecules

Notice that in the two figures above, the two strands of a DNA molecule are antiparallel, that is, they run in different directions The side of the chain on DNA has a structure called a double helix Nucleotides are attached together to form two long strands that spiral to create this structure If
