<span>Physical weathering is a term used in science that refers to the geological process of rocks breaking apart without changing their chemical composition. Over time, movements of the Earth and environment can break apart rock formations, causing physical weathering.</span>
PH = - log [H+]
Transpose and solve for H+
3 = - log [H+]
H + =
= 0.001 M

DNA polymerase is an enzyme with a specific active site complementary to the 3' OH end of the DNA strand in terms of charge, size, orientation and shape thus can only bind to 3' end and cannot bind to 5' end for replication to occur
