What are the triangles and double circle around the bases?

I’m sure this is documented online, but I went through the initial tutorial a second time, and have tried to scour the menus, and can not find a guide. My apologies if this is covered somewhere obvious that I have just missed.

Hi David!

The small triangles turn the nucleotides in to little packmans and show the reading direction of RNA. From base 1 and up.

How do I interpret ‘reading direction’ when there are 2 triangles in motion, from about 90 degrees to 10?

Check the parts of the puzzle that is not moving. Like the strings. Or when the “packman’s” are in the closed 10 degree position, then they point in the correct direction. Think they are moving to give people a feeling of game and action.
