So c) guanine Source(s): bp guanine You little bio cheater! You're taking the easy way out .
It changed to either a T or a C.
The base that changed is the 2nd G of the trp codon .
Codons for cys are TGT or TGC.
Codon for trp is TGG.

Put 'DNA structure' into your browser up.
The structure of the DNA molecule is a double helix, which is like a twisted ladder.
I had to spend hours in libraries to do my work .

Thymine (T)
2.AdenineDNA stands are made of a nitrogen base, Deoxyribose (sugar), and Phosphate.
The nitrogen bases are the "steps to the DNA ladder."
There are 4 DNA bases:

So it would read, but it's easier to go back to your original DNA sequence and just change all your T's to U's.
RNA doesn't have Thymine, so when you're done, change all your T's to U's.

Have a look if ....
Cytosine will bond with guanine, thymine, deoxyribose, and a phosphate group, and this is what covalently links the sides of the DNA ladder in the ladder.
Of these bases in DNA, and only two possible combinations.

DNA
- has 2 strands
- deoxyribose is its sugar molecule
- its Nitrogen bases are Cytosine, Guanine, Adenine and Thymine
- it's in the nucleus
RNA
- has 1 strand
- ribose is its sugar molecule
- its a few i could pull off the top of my head....
