The top and bottom of the final tutorial puzzle are in the links area. When I try to place a color there, it takes me to the linked page instead of applying the color. Then I have to start the puzzle over. Frustrating. Nancy
Hello Nancy,
You can click on the blue background and move an RNA to left-right or up-down. You can also adjust the Zoom by clicking on +, - icons listed in the bottom links.
I hope this helps, and please don’t hesitate to write if you have further questions.
