Which of the following statements most closely describes the quaternary structure change of deoxyhemoglobin when it binds oxygen? Group of answer choices the hydrophobic core of each monomer undergoes significant repacking the two beta chains of the molecule get closer by about 7 Angstroms the two beta chains of the molecule get closer by about 7 nanometers one alpha/beta dimer of the tetramer rotates by 90 degrees with respect to the other a new set of noncovalent contacts forms between the two alpha subunits
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.
