Describe the structure of DNA. ➢ DNA is a nucleic acid‚ which consist of long chains (polymers) of chemical units (monomers) called nucleotide. A molecule of DNA contains two polynucleotides‚ each a chain of nucleotides. Each nucleotide consists of a nitrogenous base‚ a sugar‚ and a phosphate group. Each DNA strand serves as a mold‚ or template‚ to guide reproduction of the other strand. There are four different types of nucleotides found in DNA‚ differing only in the nitrogenous base. DNA is contained
