3 simple steps for DNA duplication
I have found so many answers but cant get a concise one.
1. separation - of 2 dna strands unzips ?
2. duplicates ?
3. zips back up ?
and then a simple sentence about each
Since this is not my area of expertise, I searched Google under the key words "steps for DNA duplication" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

Don't just copy the material. Express the ideas in your own words. Although this will take more time and effort, you will learn more.
Certainly! Here are three simple steps for DNA duplication, also known as DNA replication:
1. Separation: The first step involves the separation of the two DNA strands. This process, known as DNA unzipping or denaturation, occurs when the hydrogen bonds between the complementary base pairs (A-T and G-C) are broken. As a result, the two strands of the double helix separate from each other, forming a replication fork.
2. Duplication: Once the DNA strands are separated, the next step is duplication. Enzymes called DNA polymerases act as molecular photocopiers and move along each of the original DNA strands. These enzymes synthesize new strands by adding complementary nucleotides to each exposed DNA template strand. The rule of base pairing ensures that the newly synthesized DNA strands are complementary to their respective template strands. This process results in the formation of two identical DNA molecules, each consisting of one newly synthesized strand and one original strand.
3. Zip-back: After the DNA strands have been duplicated, the final step is the zipping back up or rejoining of the newly synthesized strands with their original template strands. The complementary nucleotides in the newly synthesized strands rejoin with their corresponding nucleotides in the original strands, facilitated by DNA ligase enzymes. The hydrogen bonds between the base pairs are reestablished, ensuring the restoration of the double-stranded DNA helix.
In simpler terms, DNA duplication occurs in three steps: separation of the original DNA strands, duplication of new DNA strands using the original strands as templates, and finally zipping back up or rejoining of the newly synthesized strands with the original strands.
