DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).The order of these bases is what determines DNA's instructions, or genetic code.NA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
DNA is present in the nucleus of every cell. The nucleotide bases present in the DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).The original structure of the DNA molecule is a double helix.DNA is a double stranded structure. It is transcribed from a DNA template.On the mRNA nucleotides are arranged into codons consisting of 3 bases each.Each such codon specifies an amino acid. 2  tRNA-This RNA type is a small chain of about 80 nucleotides. 3  As the name suggests, tRNA transfers specific amino acid molecules to a growing polypeptide chain.
