Biochemistry : Nucleic Acids Quiz
Nucleic acids are the fourth class of biological molecule. They store information. A nucleic acid is a nitrogen containing biological polymer that is involved in storage and transmission of genetic information.
The monomer that makes up a nucleic acid is called a nucleotide. Each nucleotide has three parts: 1. Inorganic phosphate group, 2. A five-carbon monosaccharide sugar, and 3. A nitrogen base.
In a nucleic acid, the sugar of one bonds to the phosphate of another. This makes them string together in a chain. Each sugar is also bonded to a nitrogen base.
DNA and RNA are nucleic acids. DNA carries genetic information. RNA allows cells to use the information found in DNA, and determines the sequence of amino acids that form proteins. DNA consists of two long chains of nucleotides wound together to form a spiral structure. The sugar is deoxyribose, and there are four nitrogen bases: adenine, thymine, guanine and cytosine. RNA is single stranded, and the sugar is ribose, with nitrogen bases A C G and U, which is uracil.
