DNA polymerases in general cannot initiate synthesis of new strands, but can only extend an existing DNA or RNA strand paired with a template strand. To begin synthesis, a short fragment of RNA, called a primer, must be created and paired with the template DNA strand.

At night, it is possible to see the flashes of lightning from very far distances, up to 100 miles (160 kilometres), but the sound does not carry that far. In Florida, this type of lightning is often seen over the water at night, the remnants of storms that formed during the day along a sea breeze front coming in from the opposite coast.

The game follows the ``Adult Link'' timeline, after Link, the ``Hero of Time'', defeats Ganon and time-travels back to his childhood. A crisis emerges when Ganon returns, but Link does not. Centuries later, the people live on islands in the Great Sea. They preserve Link's story as a legend, but his kingdom's fate is unknown. The main character, a young boy also named Link, lives on Outset Island, where boys dress in green like the Hero of Time when they come of age.
