Question

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

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

Answer 1

The correct option is D DNA fingerprinting - DNA profiling

Genome represents the total amount of DNA present in the haploid set of chromosomes of an organism while gene pool is the sum total of genes of a population. A specific sequence of three DNA or RNA nucleotides that represents a specific amino acid or stop signal during protein synthesis is termed as codon while gene is physical and functional unit of heredity that carry instructions for protein synthesis. A gene has a sequence of codons that determines the sequence of amino acids in the proteins. Since, a codon is a sequence of three nucleotide bases, it is also termed as triplet while a gene is also termed as cistron because it exhibit specific cis-trans behaviour. DNA fingerprinting identifies and evaluates the genetic information of an individual based on the fact that no two person carry same nucleotide sequence of DNA. DNA profiling also refers to decipher the person's characteristics based on its genetic material. Hence, DNA fingerprinting and profiling are same things.
