How does DNA change to mRNA?

Answer 1

First up, DNA technically doesn't "change" into mRNA; it is transcribed into mRNA. In other words, an mRNA sequence is made based on the template from the DNA.

So basically, an enzyme called RNA polymerase binds to the DNA. Then, it unzips the strand, and creates a complementary base sequence of RNA nucleotides. This forms an mRNA strand.

This video by Crash Course provides an explanation of how this works, and what is done after that.

Hope it helps :)

DNA is transcribed into mRNA through a process called transcription. During transcription, an enzyme called RNA polymerase binds to a specific region of the DNA called the promoter. RNA polymerase unwinds the DNA double helix and reads one of the DNA strands as a template. It then adds complementary RNA nucleotides to the growing mRNA strand according to the base pairing rules (A with U, T with A, C with G, and G with C). Once the mRNA molecule is synthesized, it detaches from the DNA and can then be processed and translated into proteins.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
