Given the following tRNA anticodon sequence, derive the mRNA ?

mRNA - 5' AUG AGA GCU CCG 3'

DNA - 3' TAC TCT CGA GGC 5'

Protein - N' Start (Met)- arg - ala - pro- C'.

EDIT -

DNA is complementary to mRNA and mRNA to tRNA or opposite.

From tRNA to mRNA, replace A by U and C by G or converse.

So, UAC of tRNA will be AUG in mRNA.

Now DNA doesn't have U in it, istead has Thymine (T).

Hence AUG will be TAC in DNA.

Other ways of finding DNA if tRNA is given is to replace all the Us with Ts in tRNA.

And to find protein you should have codon table with you, unless you remember it all.

Here's a link for it.

Suppose you have to search amino acid for AGU, you need to look for A at the left, then corresponding to that G above and U in the same to the right. (Like first base, then second and then third).

mRNA: AUGAGAGCUCCG

DNA: TACTCTCGAGGC

Protein (amino acids): methionine arginine alanine proline

For RNA A>>U & C>>G &vice versa

For DNA A>>T & C>>G & vise versa + U>>A

For protein: you have to look for the table to match each codon (ex UAU) with its amino acid.
