DNA Replication starts with 1 molecule of DNA and ends with 2 molecules of DNA.

DNA Replication starts with 1 molecule of DNA and ends with 1 molecule of DNA and 1 molecule of RNA.

DNA Replication starts with 1 molecule of DNA and ends with 2 molecules of RNA.

DNA Replication starts with 1 molecule of DNA and ends with 1 molecule of DNA.

Both DNA helicase and DNA polymerase are used to build proteins during DNA Replication.

DNA polymerase is the enzyme that separates the double stranded DNA and DNA helicase is the enzyme that matches the free-floating nucleotides to the broken DNA in order to create 2 complete strands of DNA.

DNA helicase is involved in the breaking of sugars and phosphates and DNA polymerase is responsible for building new helicase enzymes.

DNA helicase is the enzyme that separates the double stranded DNA and DNA polymerase is the enzyme that matches the free-floating nucleotides to the broken DNA in order to create 2 complete strands of DNA.
