Why Would Much Larger Satellite DNAs Be Unlikely to Form

Why would much larger satellite DNAs be unlikely to form satellites in density gradients?

A) Larger satellites are less likely to have a base composition similar to that of the bulk of the genome.
B) Larger satellites have higher molecular weights than the bulk of the genome.
C) Larger satellites will have the same molecular weight as the bulk of the genome.
D) Larger satellites are more likely to have a base composition similar to that of the bulk of the genome.
E) Larger satellites have the same charge as the bulk of the genome.
