A strand or RNA reads GCAUUGCAAGUC. What is the sequence of amino acids coded for by this strand?
aliya0001 [1]

Then just divide the RNA strand into sets of 3 bases and you can easily identify the amino acids which it is going to transcribe. There are certain tools available online in which you can input your RNA strand sequence and they will return the protein (amino acid) sequence resulting from that strand. hope it helps :D
