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.
Copying occurs at a localized region called the replication fork, which is a Y shaped structure where new DNA strands are synthesised by a multi-enzyme complex. Here the DNA to be copied enters the complex from the left.One new strand is leaving at the top of frame and the other new strand is leaving at bottom.The first step in DNA replication is the separation of the two strands by an enzyme called helicase.he other half of the DNA double helix, known as the lagging strand, has the opposite 3' to 5' orientation and consequently requires a more complicated copying mechanism. As it emerges from the helicase, the lagging strand is organised into sections called Okazaki fragments.
