Pauling's model couldn't be right because: A. the negative oxygen atoms of the phosphate groups would repel in the middle of the molecule B. the bases on the outside would be attracted to each other and crush the molecule C. he forgot about the sugars D. the positive phosphate groups would repel each other in the middle of the molecule
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.
DNA or deoxyribonucleic acid is the genetic material in most organisms.
According to Pauling's structure of DNA was a triple helical structure. That means it was having three DNA strands wound together, instead of just the double-helical structure given by Watson and Crick where the DNA has two strands. The authors summarize how their model of DNA fits with most of the x-ray diffraction.
