Which one of the following pairs of terms / names mean one and the...

Gene pool is the total gene present in a population. Genome is the total genetic constitution of an organism. Codon is the basic unit of genetic code, a sequence of three adjacent nucleotide in DNA or $m$ RNA that code for an amino acid. Gene is the basic unit of heredity, a sequence of DNA nucleotide that encodes a protein. Cistron is a segment of DNA nucleotides that codes for a polypeptide chain. Triplet is a three nucleotides sequence coding for an amino acid. Therefore, $$\begin{aligned}& \text{ codon } \approx \text{ triplet }\\ & \text{ cistron } \approx \text{ gene } \end{aligned}$$DNA fingerprinting is technically called DNA profiling or DNA typing.
