The enzyme dna polymerase works only in the 5′ to 3′ direction. how does this affect the leading strand and the lagging strand? a. dna polymerase can work on both the leading and the lagging strand but is much faster on the leading strand. b. dna polymerase can use only the leading strand as a template. a different enzyme is used to synthesize dna on the lagging strand. c. dna polymerase can work continuously on the leading strand but works discontinuously on the lagging strand, creating okazaki fragments. d. dna polymerase can work continuously on the leading strand but must flip the lagging strand around before it can work on it.

Read this summary of a scientific theory: "cells are the most basic structural and functional units of life. all living organisms are made up of one or more cells. all cells that are alive in the world today came from pre-existing cells." which of the following would require this theory to be modified? -a.) a survey finds that a majority of people believe viruses carry out the basic processes of life. -b.) a prominent scientist says she feels strongly that one day the theory will be challenged by life on other planets. -c.) the dna of unicellular and multi-cellular organisms is shown to have many fundamental similarities. -d.) scientific observations show that microscopic organisms living in the deep ocean are not made up of cells.
