Question

Study of genes and genomes by DNA sequencing and its related analysis is called ______.

• A. Hydroponics
• B. Genomics
• C. Biofortification
• D. Systematics

Hint:

Genomics focuses on the entire genome, while genetics often studies individual genes.

Answer 1

The Correct Option is B

Step 1: Understanding the term genomics.
Genomics is a branch of biology that deals with the comprehensive study of the complete DNA sequence of an organism, including all of its genes and non-coding regions.
Step 2: Role of DNA sequencing.
DNA sequencing is the primary tool used in genomics to determine the exact order of nucleotides in genes and genomes, followed by computational analysis to understand gene structure, function, and regulation.
Step 3: Analysis of options.
(A) Hydroponics: A method of growing plants without soil.
(B) Genomics: Correct, it involves genome-wide DNA sequencing and analysis.
(C) Biofortification: Improvement of nutritional quality of crops.
(D) Systematics: Classification and evolutionary relationships of organisms.
Step 4: Conclusion.
The study of genes and genomes using DNA sequencing and analysis is called genomics.
