You are working in a biotechnology lab arid are analysing DNA. You obtain a sample of a short dodecamer of DNA that contain 12 base pairs. What must the ratio of adenine to thymine be in your sample? What must be ratio of cytosine, to guanine be in your sample? Assume the counter ions present in your DNA solution are sodium ions. How many sodium ions must there be per dodecamer? Assume the 5’ end phosphate each bear a-1 charge.
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
