This is DNA, in the strand there are 9 nucleotides. The nucleotides are made up of a sugar, nucleic base and a phosphate.
This is arrow is suppose to represent the Helicase splitting up the DNA.
- This is primase, it makes RNA primer

This is what the DNA strand will look like after the Helicase splits it. Replication will now start to commence.

As you can see the final product is two DNA strands. When DNA replication takes place the leading strand is synthesized continuously but the lagging strand is synthesized discontinuously.
Additional Information
Telomeres are the long stretches at the ends of chromosomes in noncoding DNA. Telomeres are vital when it comes to a cell, this is because they keep the chromosomes from attaching to each other in the cell.
DNA Ligase stitches the Okazaki Fragments together
Telomerase is an enzyme that helps aid cell is maintaining the length of their telomeres.
