WebbThe hydrolysis of a peptide bond is helped along by two common means, and those two means are with the help of strong acids or with proteolytic enzymes. So when we use strong acids, we call this acid hydrolysis. And acid hydrolysis, when combined with heat, is a nonspecific way of cleaving peptide bonds. WebbSolution. The correct option is B a phosphodiester bond within a specific sequence. Restriction endonuclease is an enzyme produced chiefly by certain bacteria. This enzyme cleaves the phosphodiester bond within or near a …

WebbRestriction enzymes are the endonucleases which cleave the DNA at specific sites. These enzymes act on the phosphodiester bond which attaches two nucleotides in the polynucleotide chain. There are specific restriction sites at which the enzymes make blunt or staggered cuts to produce the fragments of the DNA. Thus, the correct answer is … WebbExonucleases work by cleaving nucleotides one at a time from the end (exo) of a polynucleotide chain. A hydrolyzing reaction that breaks phosphodiester bonds occurs at either the 3’ and 5’ end.
