Question

If the following were part of a DNA chain, what mRNA bases would pair with it to transcribe the DNA code onto mRNA? G-G-A-T-C-G-C-C-T-T-A-G-A-A-T-C

Answer 1

Okay. To help you out, I will tell you about the DNA-RNA BASE PAIRING rule.

Let's take a look at that whole chain of letters.

Each of those letters is a BASE.
And each base has a PARTNER.

When DNA is transcribed into RNA,
each of the DNA's bases gets to meet its partner!

And here are the partners,
going from DNA to RNA:

A goes with U
T goes with A
G goes with C
C goes with G

You see?
Those are the partner rules, for DNA and RNA.

So, for example,
during transcription, when RNA is being made from DNA...

whenever there is an A on the DNA,
the RNA will get a U.

Whenever there is a T on the DNA,
the RNA will get an A.

You see?

Let's look at your DNA chain here:

G-G-A-T-C-G-C-C-T-T-A-G-A-A-T-C



So, the first three DNA bases are....G G A.

So...the first three RNA bases would be....C C U.

You see?

All we need to do is remember the partner rules, for DNA and RNA.
