the amino acid serine is..? The DNA strand CGA AGT GAC ATT undergoes a mutation in which the section coding for the amino acid serine is lost. Which of the following would be the correct codon sequence after this mutation?

a) ACG CUG UAA
b) GCU ACG CUG
c) GCU CUG UAA
d) GCU ACG UAA
 
B. this is why:

going from DNA to RNA, A matches up with U, and C with G.

So, if you follow your DNA sequence with this rule, letter B all of the letters match up with their partner, except two, and that is in the second set of letters ACG, it should be UCA.

hope that helps!
