MCAT Flashcards: Monocistronic mRNA

What is Monocistronic mRNA? Ken Tao is an MCAT expert and explains that it is mRNA that codes for one protein product. Monocistronic transcripts are found in eukaryotes.

In this flash card video, we’re going to discuss “What is Monocistronic mRNA?”

Monocistronic mRNA is mRNA that codes for a single protein product. Generally eukaryotes have Monocistronic mRNA. Monocistronic mRNA gives eukaryotes a lot of flexibility in being able to express different genes in different cells. For example you can have one cell and a multicellular organism express proteins A and B, and another cell expressing proteins A and C, and another so expressing proteins B and C.

This is because each of these proteins A, B, and C are produced by different mRNA molecules that can each be regulated independently.
