Which one of the following statements about hydrogen bonds is FALSE? O hydrogen bonds are the strongest type of bonds. beta sheets in proteins are formed from extensive hydrogen bonding. O hydrogen bonds stabilize the tertiary structure of proteins. O hydrogen bonds are absent in the primary structure of proteins.
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.
Hydrogen bonds are intermolecular forces that act between two molecules. These bonds are formed when a hydrogen atom is located between two electronegative atoms. The electronegative difference must be high which can be formed with fluorine, nitrogen and oxygen only.
