During DNA replication in the cell, DNA primase makes short primers that are then extended by the replicative DNA polymerases. These primers …

A) are made up of DNA.
B) generally have a higher number of mutations compared to their neighboring DNA.
C) are made more frequently in the leading strand than the lagging strand.
D) are joined to the neighboring DNA by DNA ligase.
E) provide a 3′-phosphate group for the DNA polymerases to extend.
