The phosphate group in dna
WebbIn organic chemistry, phosphate or orthophosphate is an organophosphate, an ester of orthophosphoric acid of the form PO 4 RR′R″ where one or more hydrogen atoms are replaced by organic groups. An example is trimethyl … Webbin a single strand of DNA, the phosphate group binds to the __________ of the next group thymine and guanine chargaff's rule states that the DNA of any species contains equal amounts of adenine & _____________ and also equal amounts of _____________ & cytosine adenine in DNA thymine is complementary to (or pairs with) what? guanine

Webb1 mars 2024 · DNA and RNA are made up of monomers known as nucleotides. The nucleotides combine with each other to form a polynucleotide, DNA or RNA. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar, and a phosphate group (Figure 1.1. 1 ). WebbIts structure is described as a double-stranded helix held together by complementary base pairs. The basic units of DNA are nucleotides. These nucleotides consist of a …
WebbDNA solutions of 113 bp and 2000 bp (0.1 mg mL −1) were prepared in NaCl 0.01 M. Then, ethidium bromide was added in the DNA solutions at a molar ratio, [EtBr] = [P]/4, where [P] corresponds to the molar concentration of DNA phosphate groups. The DNA solutions containing EtBr were left overnight to equilibrate. WebbThe pKa of phosphate groups in DNA or RNA is 2 and gives a negative charge at neutral pH (pH=7). This charge-charge repulsion forces the phosphate groups to take opposite …
Webb18 jan. 2024 · In the case of DNA, which has ten phosphate groups per turn (pitch P), we generate ten holes per wavelength (see Fig. 5). This pattern was created by first plotting a sine wave using Maple. The ratio of amplitude to wavelength of the sine wave was the same as the ratio of radius to pitch of the DNA.
