The Story Supplement
Alina, Tristan, Gina and Crispin are the Dinky Amigos and represent four chemicals known as bases. They join with each other in pairs and appear many times to create DNA – the genetic information that makes us who we are. As we grow, we need more DNA, which must be copied exactly. This copying process is called replication and is part of a larger copying process known as mitosis.
DNA exists as two rows of Dinky Amigos lined up in the same order. One row faces forward whilst the second faces the opposite way. Both rows are twisted together like a spiral. This is known as a double helix where Alina always stands opposite Tristan, and Gina always stands opposite Crispin.
During mitosis, the double helix must be prised apart so that each row (or strand) can be copied separately. This copying involves new Dinky Amigos who stand opposite those from the original strand.
For their own safety, the Dinky Amigos need to stand in a double row. They also like to play and dance. But, when they go on the orange slideabout, the double row gets separated. The Dinky Amigos facing forward go one way (to the Lead dance) whilst those facing the opposite way are sent to the Lag-O-Frag dance.
Only through dancing can the Dinky Amigos meet new friends to help them create two new double rows and be safe once more.
Not all the Dinky Amigos have been to a dance before, so they need help. Most of this help comes from Ana. She shows them to the right dance hall and stays to help with the Lag-o-Frag dance. She even makes sure there are balloons so the Dinky Amigos have a good time!
