30 points these steps of dna replication in the order in which they occur.
rna primase synthesizes rna primer,
which attaches itself at the initiation point,
polymerase begins synthesizing the new
strands
single-strand binding proteins prevent the
strands from snapping back to the original
dna structure
ligase joins the okazaki fragments.
helicase unwinds the parent dna strand

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.

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.
