Explanation / Answer

An amino acid is coded by a sequence of three unique nucleotides called codon that are at times degenerate. Hence an enzyme isolated from tobacco leaves having 192 amino acid residues has 192 x 3 i.e. 576 nucleotide base pairs. Since in a gene, there are noncoding regions (introns) and coding regions (exons) the number of base pairs is 1500 bp. The noncoding regions will be spliced off to get an mRNA that will be translated to an enzyme of 192 amino acids.
