Select the false statement. The canonical B-DNA structure Is formed by G-T and A-C nucleotide pairs. Dissociates into single strands at a melting temperature. Features parallel stacks of nucleobase pairs. Features a minor grove that is deeper and wider than that in an A form. Requires about 10 nucleotides for a complete helical turn.
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.

- Is formed by G-T and A-C
nucleotide pairs. - Dissociates into single strands at a melting temperature.
- Features parallel stacks of nucleobase pairs.
- Features a minor grove that is deeper and wider than that in an A form.
- Requires about 10 nucleotides for a complete helical turn.
The question presents a set of statements about the canonical B-DNA structure, a particular shape of DNA that's most common beneath physiological conditions. The task is to recognize which statement is untrue. This requires a strong understanding of molecular biology and the particular properties of B-DNA.
