Today I continued working on the challenges on EteRNA and have continued to learn little key tips to strengthen the RNA strands.  I am still having a problem with the switch RNA and finding a way to have the strand work in both forms. Today I finished my 50th puzzle and completed the second round of puzzle master.  I keep attempting the labs though my problems with doing switches is making them even harder.  I will continue to practice switches and will also begin to study RNA outside of the EteRNA website.
