17. the enzyme dna polymerase works only in the 5' to 3' direction. how does this affect the leadingstrand and the lagging strand? a. dna polymerase can work continuously on the leading strand but must flip the lagging strand aroundbefore it can work on it. b. dna polymerase can use only the leading strand as a template. a different enzyme is used to synthesizedna on the lagging strandc. dna polymerase can work continuously on the leading strand but works discontinuously on the laggingstrand, creating okazaki fragmentsd. dna polymerase can work on both the leading and the lagging strand but is much faster on the leadingstrand

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
