Which of the process makes copy of a dna moleclue

I hope it helps;

Explanation:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.

DNA copies itself before cell division so that each new cell has the full amount of DNA. What is method by which DNA replicate? the enzyme DNA helicase breaks the hydrogen bonds between bases on the two polynucleotide DNA strands.

Thanks
