Question

6. The gene for a large single eyeball is coded by the gene sequence TTCGCTGAA. Let’s go through transcription…
DNA Strand- T-T-C-G-C-T-G-A-A
mRNA Strand- _____________________________
7. Now, let’s look at the gene for green body color, which is GGACTCTAG. With your group (or on your own if you are not completing this with us live), determine the complementary mRNA strand…
DNA Strand 2- G-G-A-C-T-C-T-A-G
mRNA Strand 2 _____________________________


Biology isn't my strong suit, can anyone help? I'm after an explanation more than answers..

Answer 1

6. A-A-G-C-G-A-C-U-U
7. C-C-U-G-A-G-A-U-C

Answer 2

Could you explain on how you get that?

Answer 3

Hey just wanna know if u want the explanation since u have already given the medal !

Answer 4

I would appreciate that.

Answer 5

okai

Answer 6

Bases of DNA are Adenine (A), Guanine (G) , Cytosine ( C) and Thymine (T)
Bases of RNA are Adenine (A), Guanine (G), Cytosine (C) and Uracil (U)
So basically RNA has uracil (U) instead of thymine (T)

This is how the base pairing works
In DNA : Adenine (A) pairs up with Thymine (T) and Guanine (G) pairs up with Cytosine (C)
In RNA : Adenine (A) pairs up with Uracil (U) and Guanine (G) pairs up with Cytosine (C)

Answer 7

Adenine and Guanine go together, Cytosine and Thymine go together and Cytosine and Uracil go together correct?

Answer 8

So in the first question they have given us the DNA base pairs and asked us for the RNA base pairing for it right?
DNA Strand- T-T-C-G-C-T-G-A-A
RNA strand -A-A-G-C-G-A-C-U-U

Answer 9

No no no
Adenine pairs up with thymine
Guanine pairs up with cytosine
That is DNA
In RNA the only difference is that it has no base called Thymine instead it has uracil
Therefore Adenine will pair up with uracil
This is in RNA

Answer 10

It asks directly in the question for transcription. I watched a Crash Course video on it, but I didn't quite get it.

The other one wants the comp. RNA strand it says.

Answer 11

And RNA is single strand rather than the double helix DNA.

And it doesn't RNA have another difference in the phosphate?

Answer 12

How would you get the transcription and complimentary strands?

Answer 13

Okia ! The only difference here when base pairing is that instead of thymine Adenine pairs up with uracil

Answer 14

DNA Strand- T-T-C-G-C-T-G-A-A
This is the first question right?
SO imagine u had another DNA stand instead of mRNA
Then the base pairing would be as I said ! Thymine (T) pairs up with Adenine (A ) and vice versa
Guanine (G) pairs up with Cytosine (C) and vice versa!
So the complimentary base pairing for another DNA strand would be
A-A-G-C-G-A-C-T-T
dO U GET THIS PART ?

Answer 15

So if I had A-T-T-C-G-C-T-C-A-A (hypothetically) it would be T-A-A-G-C-G-A-G-T-T?

Answer 16

yeah if it is another DNA strand which is pairing up !

Answer 17

And if the other was G-G-A-C-T-C-T-A-G it would be C-C-U-G-A-G-A-U-C?

Answer 18

The only difference of DNA base pairing and RNA base pairing is that Adenine pairs up with Uracil. But if u have a thymine to pair up with it would be an adenine (A)
SO for this DNA Strand- T-T-C-G-C-T-G-A-A
RNA strand -A-A-G-C-G-A-C-U-U

Answer 19

So what I said about G-G-A-C-T-C-T-A-G is correct?

Answer 20

Yep !

Answer 21

Ok thanks.

Answer 22

No problem :)

Answer 23

I hope u get it now :)

Answer 24

There's another part to this, can you explain that possibly?

Answer 25

@Rushwr took my place and explained it to you when i was watching el classico. Great job.

Answer 26

if you still need any help i'm here to help you out.

Answer 27

Thank you @rhr12
