DNA Structure and Components Quiz

The components of DNA are sugar, nitrogenous base, and phosphate. The polarity of the DNA molecule is 5'-3', with one end chemically different from the other end. The 5' end contains a phosphate group, and the 3' end contains OH.

DNA is a linear polymer of nucleotides. It has a backbone consisting of alternating sugar and phosphate groups, connected by phosphodiester bond. The bases project away from the backbone. The DNA molecule is antiparallel with complementary strands, where A pairs with T and C pairs with G.

Histones are proteins that DNA can wrap around. They play a role in packaging DNA into the nucleus and help in the folding and organization of the DNA molecule.
