Statement I:
The codon 'AUG' codes for methionine and phenylalanine.
Statement II :
'AAA' and 'AAG both codons code for the amino acid lysine.
In the light of the above statements, choose the correct answer from the options given below.
Both Statement I and Statement II are true
Both Statement I and Statement II are false
Statement I is correct but Statement II is false
Statement I is incorrect but Statement II is true.
