Which of the following statements regarding the nitrogenous base guanine is FALSE? A) ALL of these statements are TRUE B) the enol form of guanine base-pairs with thymine C) guanine undergoes a tautomeric shift between a keto and an enol form D) the keto form of guanine base-pairs with cytosine E) an alcohol (-OH) group is present in guanine's enol form, but absent in the keto form F) guanine’s keto form is more stable than its enol form
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.
