Dale makes a model of part of an elemental solid by attaching balls to each other with rods. His model looks something like the
following image:
How could Dale improve his mode
A.
by using springs instead of rods to allow the model atoms to vibrate in their positions
B.
by using strings instead of rods to allow the model atoms to move more freely
C.
by using different sizes of balls to represent different kinds of atoms
D.
by using cotton balls instead of hard balls to allow the model atoms to change size

Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
