Which one of the following pairs of terms / names mean one and the same thing?
Gene pool - genome
Codon - gene
Cistron - triplet
DNA fingerprinting - DNA profiling
Solution
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.
