Franklin, Watson, and Crick's model of DNA shows a double helical structure where two strands of
DNA run antiparallel to each other. How does this structure cause the number of purines to equal
the number of pyrimidines as observed by Chargaff?
If adenine is on one strand, guanine must be on the other strand.
If thymine is on one strand, cytosine must be on the other strand.
If adenine is on one strand, thymine must be on the other strand.
If adenine is on one strand, cytosine must be on the other strand.

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
