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.
Replication Forks and Origins of Replication. The first step in DNA replication is the separation of the two DNA strands that make up the helix that is to be copied. DNA Helicase untwists the helix at locations called replication origins.The replication origin forms a Y shape, and is called a replication fork.he first step in DNA replication is the separation of the two DNA strands that make up the helix that is to be copied.
