Use your codon chart and tell me what amino acids are coded for by the mRNA sequence AUG CGG UCC GGA

Methionine, arginine, serine, glycine  

Explanation:

Use a codon chart (attached below) to determine what amino acids are coded for by the strand of mRNA. Remember that codons are groups of three nucleotides in mRNA. So, read the nucleotides in groups of three (just as how they are separated by spaces) and from left to right.  

To use this codon chart, identify the first letter representing the first nucleotide in the codon. Then, find the matching letter that's one of the four biggest letters in the middle of the chart. Identify the second letter, then find the matching medium letter in the chart, staying within the section of the first letter as indicated by the lines, and do the same process with the third. Repeat for each codon.

Thus, with this mRNA strand, the amino acids will be methionine, arginine, serine, glycine.
