please help with all three! For DNA synthesis to take place in a Sanger sequencing reaction, the DNA polymerase must catalyze a reaction between the 3'- the last nucleotide and the 5- of the next nucleotide to be added. hydroxyl group, phosphate group O phosphate group, hydroxyl group O hydroxyl group, hydroxyl group O phosphate group, phosphate group QUESTION 6 millions of individual DNA fragments are isolated and sequenced in parallel during each machine run. O traditional whole-genome sequencing O...
