342750 The code is nearly universal: for example, from bacteria to human UUU would code for

1 Methionine
2 Serine
3 Alanine
4 Phenylalanine
BIOXII06: MOLECULAR BASIS OF INHERITANCE

342751 Assertion :
A change in nitrogen base at the third position of a codon causes change in the expression of the codon.
Reason :
The pairing of the third position bases of the codon may be ambiguous and varies according to the nucleotide present in this position.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
