PLEASE HELP!!!!!!!!!!!!!!!!!!!! DNA mRNA tRNA

Post by syrNYstudent » Sun Apr 24, 2005 8:46 pm

The Neucleotide of a DNA codon is GTA.

The mRNA codon is CAU.

The tRNA anticodon is GUA.

In DNA, G and C pair together. A and T pair together.

In RNA, it is the same as above, except that instead of T, U is used.

Then your DNA codon is GTA.
It makes a counterpart in mRNA. Following the pairing rules, CAU is the codon.
The CAU codon pairs up with a GUA codon of a tRNA...and GUA tRNA's always grab an Aspartic Acid to bring to the polypeptide being formed.

its way easier than that,
as a fellow confused bio person just try to remember that U is T when your dealing with RNA not DNA remember thia and it cant go wrong!

You are right, however did you ever think that it may be important why it is like that? You can not expect to know genetics if you do not understand it
