9. Nucelotides and nucleic acids: The primary function of nucleic acids is to store genetic material. (a) Describe in as much chemical detail, the structural features of nucleotides and DNA (deoxyribonucleic acid) that allow for storage of genetic material. Include in your discussion the weak, non-covalent forces that stabilize DNA. (b) Describe in as much chemical detail, mechanisms by which nucleotides can be damaged and how this can affect the fidelity of storage of that genetic material and potentially lead to biological effects.

Step 1
A nucleotide consists of three components: a nitrogenous base, a pentose sugar, and a phosphate group. In DNA, the nitrogenous bases are adenine (A), guanine (G), cytosine (C), and thymine (T). The pentose sugar in DNA is deoxyribose, which has one less hydroxyl Show more…

1. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. Explain the structural properties of DNA which can relate to DNA replication and protein synthesis in the prokaryotic cells. [10 marks]

Nucleic acids are (choose all that apply) polymers of amino acid chains polymers of nucleotides such as adenine, cytosine, guanine, thymine if in the form of DNA, are primarily found in the nucleus of eukaryotes the independent variable the way that organisms store their genetic "blueprints" composed of a nitrogen-containing base, a 5-carbon sugar, and a phosphate group
What is the defining feature of nucleic acids? a. They contain one or more nitrogenous bases, pentose sugars, and phosphates. b. For every carbon atom, they have two hydrogen atoms and one oxygen atom. c. They contain nitrogen molecules and amino groups.
