MCAT Flashcards: Non-Coding RNAs

What are non-coding RNAs? Ken Tao is an MCAT expert and explains that non-coding RNAs are RNA molecules that do not code for a protein product. There are many kinds of non-coding RNAs, and in this video, we’re going to go over the important ones for the MCAT.

Non-coding RNAs are RNA molecules that do not code for a protein product. This means that non-coding RNA do not include messenger RNAs that do code for a protein product.

There are many kinds of non-coding RNAs, and in this video, we’re going to go over the important ones for the MCAT.

First, we have transfer RNAs which bring amino acids to ribosomes during translation. We also have ribosomal RNAs that are a component of ribosomes as well as small nuclear RNAs that are a component of spliceosomes. We also have microRNAs, small interfering RNAs, and short hairpin RNAs that are all involved with regulating gene expression.
