Answer #1

Option C is correct , nucleus and RNA isomerase.

DNA present in nucleus and it's replication takes place in nucleus. For DNA replication DNA POLYMERASE, RNA primase, DNA ligase required.

DNA POLYMERASE form new DNA strand by using single original DNA strand. By using deoxynucleotides it build up new strand.

rna primase catalyzes the synthesis  of a short RNA or DNA in some organisms segment called a primer complementary to a ssDNA (single-stranded DNA) template.

DNA ligase is an enzyme which can connect two strands of DNA together by forming a bond between the phosphate group of one strand and the deoxyribose group on another. It is used in cells to join together the Okazaki fragments which are formed on the lagging strand during DNA replication.
