WebBiology questions and answers. 3. (9 points) a) The enzyme DNA ligase catalyzes the formation of a phosphodiester bond between a 3-hydroxyl at the end of one DNA strand and a 5'-phosphate at the end of another strand. Eukaryotic DNA ligase requires ATP for this reaction to activate the 5'-phospghate group. WebT4 DNA Ligase catalyzes the formation of phosphodiester bonds between juxtaposed 5' phosphate and 3' hydroxyl termini in blunt-end or sticky-end dsDNA. This product also can catalyze the ligation of RNA and ssDNA or RNA strands in double strands, but it cannot catalyze the ligation of whole single-stranded nucleotides.
