A short RNA molecule was isolated that demonstrated a hyperchromic shift (see Chapter 10), indicating secondary structure. Its sequence was determined to be

     5'-AGGCGCCGACUCUACU-3'

Propose a two-dimensional model for this molecule.

Hi everyone. Let's take a look at this practice problem together. What are small non coding RNA molecules that are typically less than 200 nucleotides in length. So let's take a look at the options. We have a L n C r n A s. Now the L N C stands for long non coding RNA S. And these are sequences more than nucleotides. So a is not the correct answer. We need a sequence less than 200 nucleotides in length. B L I N C R N A S. The L I N C stands for long inter genic non coding. And these sequences are also greater than nucleotides. They differ from the LNCRNAS because they are actually a bit longer and in addition they are found in the cell nucleus. While LNCRNAS cannot be found in the cell nucleus. So that's the difference between them to either way. B is not the correct answer. Then we have C S n C R N A S. And the S N C stands for short, non coding. Now, these are the sequences that are less than 200 nucleotides long, so C. Is the correct answer. Alright, everyone, I hope you found this helpful. And I'll see you soon for the next practice problem
