When the amino acid sequence of Hb and Mb is compared, some of them are found to be the same (invariant). The reason that these residues are found in both proteins in the same positions is: (choose all the correct answers) a. They are residues found on the carboxyl terminal side of Mb and Hb that help their solubility. b. They are part of the surface of Hb and Mb that help their solubility. c. They are crucial residues for the function of these proteins. d. They are residues that have been conserved evolutionarily.
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.
