Suppose during transcription of DNA code AAA, a mistake occurs due to which UUG code of RNA is formed. Due to this what change in picking the type of amino acid would occur during synthesis of protein.

Solution
AAA code of DNA would have transcribed UUU code on mRNA which code for phenylalanine amino acid. Due to change in code on mRNA, UUG is coded and it will code for a different amino acid. UUG will code for leucine amino acid.
