Itâs extremely unlikely that youâre ever going to become rich doing photography. In fact, if this is your only income and you have a family, itâs a hard income to live off of and youâre going to have to make sacrifices. That doesnât mean you canât do it or that itâs not worth it.
1 During initiation, proteins bind to the origin of replication while helicase unwinds the DNA helix and two replication forks are formed at the origin of replication.  During elongation, a primer sequence is added with complementary RNA nucleotides, which are then replaced by DNA nucleotides.
As we go through this, remember, all that is happening is the DNA is being unzipped and each side of the zipper is being copied. The first step in DNA replication is to separate or unzip the two strands of the double helix. The enzyme in charge of this is called a helicase (because it unwinds the helix). The point where the double helix is opened up and the DNA is copied is called a replication fork.
