- Why does DNA have a leading strand and a lagging strand during replication?Select the correct row below that fills in the following blanks to answer the question above.___1st___ has to attach the new free-floating nucleotides to the ___2nd___ of the newly formed strand. The two strands of a DNA molecule are antiparallel, so in order for the lagging strand to be formed in the same direction, it has to be done in Okazaki fragments going in a ___3rd___ direction. Select one: a. 1st 2nd 3rd DNA polymerase 3' end 5' to 3' b. 1st 2nd 3rd DNA polymerase 5' end 3' to 5' c. 1st 2nd 3rd DNA ligase 3' end 5' to 3' d. 1st 2nd 3rd DNA helicase 5' end 3' to 5'arrow_forwardA space probe returns from Mars where it has collected a new microorganism. It has double- stranded DNA as its genetic material, and your studies show that it uses a semiconservative replication process.
