If a deletion occurs in a gene that encodes DNA polymerase I and no functional DNA polymerase I is produced, what will be the MOST likely consequence of this mutation?
A) The DNA strands would contain pieces of RNA.
B) The DNA would not exist in a supercoiled state.
C) There would be no DNA replication on the leading or lagging strands.
D) There would be no RNA primers laid down.
E) The DNA will not be able to unwind to initiate replication.

DNA polymerase I is responsible for removing RNA primers and replacing them with DNA nucleotides. Without functional DNA polymerase I, RNA primers would remain in the DNA strands.
