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

Answer: (D)

DNA fingerprinting - DNA profiling

Answer 2

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.Gene pool is the total gene present in a population. Genome is the total genetic constitution of an organism.

Triplet is a three nucleotides sequence coding for an amino acid. Therefore, $\quad\quad$ codon $\approx$ triplet $\quad\quad\quad$ $\quad\quad\quad$ cistron $\approx$ gene DNA fingerprinting is technically called DNA profiling or DNA typing.
