@SmokeyBrown

SmokeyBrown:

I'm not sure I understand. Are you meant to fill in the table?

Nicole:

Yes

SmokeyBrown:

Sorry, I don't really know much about DNA. I wish I could help more!

Nicole:

So you're not sure about anything? Maybe give it a try?

SmokeyBrown:

Well, I know that the bases listed are for RNA, since DNA used Thymine (T) instead of... whatever U stands for. I'm not sure about much else though.

Nicole:

Ugh lol I dont know how to do this

SmokeyBrown:

Hm, well another thing I recall is that when converting DNA to RNA, A turns into T, C turns into G, and G turns into U...

SmokeyBrown:

I'm not sure how you get from mRNA to tRNA, but if you can do that, then the corresponding amino acids are listed out for you.

Nicole:

So what would be the DNA sequence which is the first box?

SmokeyBrown:

The first box, UUU? The DNA sequence for that would be GGG

SmokeyBrown:

Wait, no, I got it wrong. AAA

Nicole:

So what would mRNA sequence be?

SmokeyBrown:

UUU is the mRNA sequence, I think.

SmokeyBrown:

To correct what I said earlier, A gets converted to U, T gets converted to A, and C and G are converted to one another.

Nicole:

What would the tRNA sequence be?

SmokeyBrown:

Ok, so if I'm not mistaken, mRNA to tRNA is similar to the conversion from DNA to mRNA in that each base has a complimentary one. In this case, A pairs with U and C pairs with G.

Nicole:

Ok so last question What would be the amino acid sequence?

SmokeyBrown:

I think you can refer to the chart for that. Based on the tRNA sequence, you should be able to find the corresponding amino acid.

Nicole:

Okay thank you.

SmokeyBrown:

You're very welcome!
