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'

If the molecule were a tRNA fragment containing a CGA anticodon, what would the corresponding codon be?

Everyone. Let's take a look at this question together. The codename of an M RNA are red in the 5 to 3 direction. The complimentary Trn a antique Odin sequence for the M RNA code on five AU G three is determined to be what so we know that M r n A and t r n a run anti parallel. And what this means is MRNA five N pairs with the T r n A three end. And so we have this M R N A sequence of five A U G three. This is the M R N A sequence, which means that our T R N A sequence which runs anti parallel and starts with a three end, is read as U A C with the five end, which means that answer choice C is the correct answer because M R n A and t r n a run anti parallel, meaning that the five end of that M r n A pairs with the three end of the T r N A. And so when we have this as R M RNA sequence, it pairs with this T RNA sequence which is answer choice C. The correct answer, I hope you found this video to be helpful. Thank you and goodbye
