Using a table that shows which codon represents which amino acid
determine the following:
A) The possible codons that encode Serine:
B) The amino acids that could be encoded if the 2nd position of the UCA codon that encodes Serine was changed to one of the other 3 bases:
C) The amino acids that could be encoded if the 3rd position of the UCA codon that encodes Serine was changed to one of the other 3 bases:
D) The amino acids that could be encoded if the 1st position of the UCA codon that encodes Serine was changed to one of the other 3 bases:
How many codons are there? How many
amino acids are coded by these codons?
How did we determine the compositions of codons encoding specific amino acids?
