Which one of the following pairs of terms / names mean one and the same thing?
(1) Gene pool - genome
(2) Codon – gene
(3) Cistron – triplet
(4) DNA fingerprinting - DNA profiling
(4) 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 mRNA 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.
