3 Codons which specify the same amino acids defer only in the third base of the triplet
4 Both 1 and 3
Explanation:
Some amino acids are coded by more than one codon, hence the code is degenerate, the codons generally differ in third base - wobble base.

The arrangement of three bases in the genetic code signifies a specific
1 Amino acid
2 Protein
3 Plasmid
4 Nucleic acid
Explanation:
The genetic code is defined as the relation between the sequence of bases in DNA and the sequence of amino acids in proteins. In fact, an amino acid is encoded by a group of three bases, or codon.

UAA, UAG, and UGA are known as non-sense codons because they
1 Do not code for any amino acid
2 Code for amino acids, which are not essential amino acids
3 Code for the initiator amino acid (methionine), which is later removed from the polypeptide chain
4 Are never present on mRNA
Explanation:
Non-sense codon is a codon for which no normal tRNA molecule occurs. Termination of translation is caused due to the presence of nonsense codon. There are three nonsense codons viz., UAA, UAG, and UGA. They do not code for an amino acid and thus signal the end of protein synthesis.
