RNA can be categorized into different types based on its role in the cell. Which type of RNA is formed after a section of coding DNA has undergone
transcription?
This question is asking us about the type of RNA that is produced following
transcription. There are many different types of RNA that are produced in the cell. Let’s go over a few of them so we can answer our question.
One type of RNA is ribosomal RNA. This RNA is structural and is part of the ribosome. The ribosome is the organelle responsible for synthesizing proteins.
Another type of RNA is transfer RNA, or tRNA. This type of RNA transfers amino acids to the ribosome so it can link them together
to synthesize proteins. It has a unique cloverleaf shape that we can see here.
And the last example we’ll look at is mRNA or messenger RNA. This RNA is produced after a protein-coding gene in DNA is transcribed. This mRNA transcript can then be translated by the ribosome to form a protein. We can see an mRNA molecule here. It contains the instructions for making a specific protein that was encoded by a
particular gene.
Therefore, the type of RNA that’s formed after a section of coding DNA has undergone
transcription is mRNA.
