Which one of the following pairs of terms/names mean one and the same thing

Options

A. gene pool - genome
B. Codon - gene
C. Cistron - triplet
D. DNA fingerprinting - DNA profiling

Answer

D

Explanation

Gene pool is the total gene present in a population. Genome is the total genetic constituent of an organism. Codon is the basic unit of genetic code, a sequence of three adjacent nucleotide in DNA or mRNA that code for a 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, codon `~~` triplet
cistron `~~` gene
DNA fingerprinting is technically called DNA profiling or DNA typing.
