1) The double helix that is the DNA is "unwound and separated by the specific enzyme helicase (DNA helicase,) thereby each singular strand can now serve as a template for newer strands (semi-conservative nature)
2) Free nucleotides within the cell then bond (hydrogen bonds) to their respective complimentary bases within the template (AT//GC)
3) And finally through the enzyme, DNA polymerase, "the phosphate of the newest nucleotide is linked to the sugar of the nucleotide before it by a covalent bond" and the "new DNA strand rewinds to form a double helix"
What is the "process of DNA replication in terms of unwinding the double helix and separation of the strands by helicase, followed by the formation of the new complimentary strands by DNA polymerase?"
