The codon AUG has dual function. It is an initiation codon and also codes for:
1 Formaldehyde
2 Methionine
3 Phenylalanine
4 Serine
Explanation:
The codon AUG has dual functions. It codes for methionine(met), and also acts as initiation codon.

UUU would code for Phenylalanine (phe). Some exceptions to this rule have been found in
1 Chloroplast codons, and in some protozoans.
2 Mitochondrial codons, and in some plants
3 Mitochondrial codons, and in some monera
4 Mitochondrial codons, and in some protozoans.
Explanation:
Mitochondrial codons, and in some protozoans.

The codons UUU and UUC codes for phenylalanine only. This feature of genetic code is called:
1 Comma- less
2 Non-overlapping
3 Degenerate
4 Non-ambiguous
Explanation:
The genetic code is degenerate. Except the two amino acids methionine and tryptophan, all others are specified by more than one codon. Two codons UUU and UUC specify phenylalanine. Six different codons specify the three amino acids leucine, serine and arginine. Three codons specify isoleucine.

Statement A : Amber codon is a termination codon. Statement B : Opal is a start codon.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
In a typical genetic code, UAA (ochre), UAG (amber) and UGA (opal) do not specify any amino acid so they are called termination codons or stop codons.

Suppose evolution on earth had occurred in such a way that there are 96 amino acids instead of 20. DNA has 12 different types of bases and DNA synthesis occurs in the same way as today. The minimum number of bases per DNA codon would be
1 12
2 8
3 2
4 3
Explanation:
If the one base is coding one amino acid, then \((12)^{1}=12\) but we have 96 amino acidsSuppose two bases form one codon, then \((12)^{2}=144\). It is sufficient to code 96 or 20 amino acids and hence two, bases from one codon.
