How is RNA different from DNA?
A) its monomers do not contain nucleotide bases
B) it is single stranded rather than consisting of a double helix
C) it consists of a triple helix rather than a double helix
D) its strands are much longer than DNA
Question 2
Which of the following correctly describes the relationship between Newton's theory of gravity and general relativity?
A) Newton's theory of gravity is now known to be false, and we were previously misled to think it was true by measurement errors.
B) Newton's theory of gravity and general relativity give the same answers, but the former tells us to think of gravity as a force and the latter tells us to think of gravity as curvature of spacetime.
C) Newton's theory of gravity is an approximation to general relativity that works when gravity is relatively weak, but breaks down when gravity is strong.
D) General relativity applies at the sub-atomic level, but Newton's theory of gravity does not.
