The codons causing chain termination are
1 AGT, TAG, UGA
2 UAG, UGA, UAA
3 TAG, TAA, TGA
4 GAT, AAT, AGT
Explanation:
The chain termination codons are UAG, UGA and UAA. They are also called termination codons, stop codons or nonsense codons.

Molecular Basis of Inheritance and
166515
Which of the following serves as a terminal codon?
1 UAG
2 AGA
3 AUG
4 GCG
Explanation:
The UAG chain-termination codon. A set of three adjacent bases in the DNA or their complementary bases in messenger RNA that specifies the end of a polypeptide chain.

166516
If the DNA codons are ATGATGATG and a cytosine base is inserted at the beginning, then which of the following will result?
1 CAT, GAT, GAT, G
2 A non sense mutation
3 C, ATG, ATG, ATG
4 CA, TGA, TGA, TG
Explanation:
Cytosine base inserted in the beginning of DNA codons ATGATGATG will produce CAT,GAT, GAT, G as genetic code reads in a contiguous manner.
