also what is the amino acid sequence produced from this strand of mRNA?

Well codons are triplets, i.e. they are sets of 3.  tRNA anti-codons are the compliment to the mRNA pairs.  A binds U and G binds C.

So,
CGG CUA ACA GUA

You'll have to consult a list to determine the AAs I don't have it memorized, but there will be 4.

In RNA, the nitrogenous bases pair in the following manner:

Adenine -- Uracil
Guanine --- Cytosine

Thymine is not present in RNA.

Hence, given the mRNA sequence, GCC GAU UGU CAU, the tRNA anticodons are as follows:

CGG CUA ACA GUA

Each codon (3 nitrogenous bases) specifies a particular amino acid.  In the mRNA sequence, there are 4 codons.  Hence, 4 amino acids will be produced.

It will produce ARG-LEU-THR-VAL as a strand so  four (?) amino acids...which is actually...

Arginine, Leucine, Threonine, and Valine.

This is what you started out with: ALA-ASP-CYS-HIS....or, Alanine, Aspartic Acid, Cysteine, and Histidine.

Let's hope thats right because its been a while since I've taken the biology course where we learned this...

I'm probably wrong but check out this website and see for yourself what the answer may be...
