Which of the following is true of RNA processing? (A) Exons are cut out before mRNA leaves the nucleus. (B) Nucleotides are added at both ends of the RNA. (C) Ribozymes may function in the addition of a 5′ cap. (D) RNA splicing adds a poly-A tail to the mRNA.

Welcome back everyone. Here's our next question which is above following statements about RNA processing is false. So let's look for our answers remembering. We're looking for a false statement. Chapter A says in tron chapter Choice A says introns are removed before M. RNA leaves the nucleus. Well this answer is true. That process is done before RNA leaves nucleus. Let's go onto Choice B. Choice B. Says the five prime end will be capped. This is also true. That is a process that helps stabilize the M. RNA molecule and helps in processing it. Choice C says the poly a tail will be added at the three prime end. Also true. That's done at the end of synthesizing an M. RNA strand and finally D. The splices OEMs remove the Exxon in pre M. R. N. A. This is false. The splices OEMs don't remove the Exxon Exxon is the coding region that stays there. The splices OEMs remove the in tron which is the non coding region of the uh of the pre RNA Pre M. R. N. A. So that is our correct answer choice D The splices owns remove the Exxon and pre arm RNA. That is our false statement. See you in the next video
