Question

One strand of a fragment of duplex DNA has the sequence 5'-ATCGACCTGATC-3'.

Which chemical groups of nucleotides react to form the bond in part (b)?

Accepted Answer

Hey, everyone. Let's take a look at this question together. A phospho dier bond is a group of strong covalent bonds between a phosphate group and 25 carbon ring carbohydrates known as ptosis over two eer bonds. Phospho dier bonds are present in which of the following biomolecules. Is it answer choice. A amino acids in a polypeptide. Answer choice B monosaccharide in a polysaccharide. Answer choice C fatty acids in a diglyceride or answer choice D nucleic acids in a nucleotide. Let's work this problem out together to try to figure out which of the following biomolecules contains a phospho dier bond. So looking at the following biomolecules, let's try to figure out what type of bonds are present. So we can determine which one contains a phospho dier bond. So starting off with answer choice A which says amino acids in a polypeptide, which we know that a polypeptide is a long chain of peptides, which we note that peptides are made up of two or more amino acids and these amino aids are linked bye peptide bonds, which means that answer choice A is incorrect because we are looking for phospho dier bonds and not peptide bonds. Answer choice B says monosaccharide in a polysaccharide, which we know that a polysaccharide is made up of more than 10 monosaccharide. And these monosaccharide are linked. Bye, like acidic bonds. And so answer choice B is incorrect because we're looking for foo dier bond and not glyco bonds. Answer choice C is fatty acids in a diglyceride which we know that and Esther bond forms a covalent bond between two fatty acid chains and a glycerol molecule to form that diglyceride. So answer choice C is also incorrect, which means that by process of elimination, we note that answer choice D nucleic acids in a nucleotide is the correct answer. And we also note that it is the correct answer because the link between two nucleotides is a link. Since we know that the nucleotide is made up of a base, a sugar molecule and a phosphoric acid molecule and between two nucleotides of nucleic acid. A phospho dier link is created. So answer choice D nucleic acids in a nucleotide is the only answer. Choice here in which a phospho dier bond is present. I hope you found this video to be helpful. Thank you and goodbye.
