Question

Accepted Answer

Hello everyone. Today, we have the following problem which of the following incorrectly describes the similarities between nucleic acids and proteins starting with a it states that both are composed of monomer units joined by covalent bonds. Well, nucleic acids, nucleic acids are actually joined by a special type of bond known as frano dier bonds. So phospho die ester bonds whereas proteins are joined or linked by peptide bonds, making choice a incorrect choice. B states that both have one letter abbreviations for their monitor units. Well, nucleic nucleotides and nucleic acids. So nucleotides maybe denote it as a TC or G in DNA. And for proteins, the amino acids can be A for a alanine, for example, or R for arginine. So choice B is correct but not our answer. Choice. C states that both have distinct left ends and right ends. Five prime to three primary nucleic acids intermit to C terminus in proteins. And this is true making choice Zarra answer. Leaving choice D that states both have a phosphate backbone providing structural support. So this is incorrect and actually our answer as only nucleic acids have a phosphate backbone. Whereas proteins just have a backbone of repeating peptide bonds overall, I hope is helped. And until next time.
