    A molecule of DNA is made up of long chains of polymers and monomers called nucleotides. Those chains, two in particular that compose a strain of DNA, are formed by the grouping of nucleotides into polynucleotides. A nitrogenous base, a sugar, and a phosphate group make up the composition of a nucleotide. In the case of DNA, the four nucleotides that are found along the chain of DNA are thymine (T), cytosine (C), adenine (A), and guanine (G). Those nucleotides are joined by their covalent bonds, more specifically the sugars and phosphates which compose the sugar-phosphate backbone of the polynucleotide.…

    Describe the structure of DNA.DNA is thread formed by two strands, related together to form a double helix. The double helix looks like a twisted ladder. The sides of this ladder are long unites called nucleotides and are made of three parts; a nitrogenous base, a sugar, and a phosphate group. The sides of the ladder or the nucleotides from the two separate strands of the DNA are attached by an appendage made of one of four separate bases. These appendages represent the rungs of the DNA ladder and are attached to the complimentary strand of the DNA. The bases or rungs are made of either Adenine (A) OR Thymine (T) or Cytosine (C) and Guanine (G). The attachment of the strands by the bases is specific Adenine can only join with Thymine, and Cytosine can only join with Guanine. Since this base pairing is specific, if one knows the sequence of bases a long one strand of the DNA one will also know the strand of the DNA one will also know the sequence along the complimentary strand.…
