DNA replication is carried out by a complex system of enzymes.

Helicase: unwinds the double helix and separates the two strands by breaking hydrogen bonds between the bases. This occurs at specific regions (origins of replication)
DNA gyrase: relieves the tensional strain caused by the unwinding of the double helix by relaxing positive supercoils that would otherwise form.
Single-strand binding proteins: these bind to the DNA strand after they have been separated to prevent them from reannealing. It is dislodged after a complementary strand is synthesised.
DNA primase: this creates short RNA primers on each strand which provides an initiation point for DNA polymerase III.
DNA polymerase III: this attaches to the 3’ end of a primer and covalently joins the free nucleotides in a 5’ to 3’ direction. On the leading strand, this movement is continuous. On the lagging strand, DNA pol III moves away from the replication fork and synthesises in pieces
DNA polymerase I: replaces RNA primers from the lagging strand with DNA nucleotides
DNA ligase: joins the Okazaki fragments together to form a continuous strand by forming phosphodiester bonds.

The process of replication:
• Each DNA strand acts as a template for the formation of a new strand.
• DNA polymerase is an enzyme that moves along the template strand in the same direction, adding one nucleotide at a time.
• Free nucleotides of each of the four bases are available in the area where DNA is being replicated. DNA polymerase brings nucleotides into positions where hydrogen bonds could form. Unless this happens, the nucleotide breaks away again.
• DNA polymerase links a nucleotide by making a covalent bond between the phosphate group of the free nucleotide and the sugar of the nucleotide at the end of the new strand.

About Capicoco Eggs

It's a coconut... with ears!? It is probably best not to eat this one...

About the Capicoco Creature

Capicocos are relaxed, happy-go-lucky creatures that enjoy nothing more than sleeping on the beach all day. They prefer to lounge in herds and rarely stray from their group. Their tails are similar to a palm tree, providing shade for themselves and others.

Domesticated Capicocos will constantly follow their keeper around to protect them from the sun and keep them company. As the Capicoco matures, its tail will start growing fruits that look just like coconuts. But be wary... these are not for consumption! These Capicoco eggs, once fully ripened, will fall off the tail and rapidly develop further, the first sign being a pair of ears breaking through the shell. Capicocos are vulnerable in this state and may become victim to other fruit-loving creatures. For this reason, adult Capicocos are always on the lookout for any potential stray eggs. Some have even been seen grooming regular coconuts, mistaking it for one of its own kind.
