Question

What is genomics?

• A. The study of genes within an organism.
• B. The study of heredity and variation in organisms.
• C. The study of the structure and function of the genome.
• D. The study of the interactions between genes and the environment.

Hint:

Genomics focuses on analyzing the genome, including the complete set of genes in an organism, and plays a critical role in understanding genetic information at a large scale.

Answer 1

The Correct Option is A

Step 1: Definition of genomics. 
Genomics is the branch of biology that focuses on the study of the genome, which encompasses the complete set of genes within an organism. It involves analyzing their structure, function, and interactions to understand genetic information at a broader level. 

Step 2: Explanation of other options. 
Option (B): Incorrect. The study of heredity and variation in organisms is the field of genetics, not genomics.

 Option (C): Incorrect. While genomics involves studying the genome, the definition specifically highlights the study of genes within an organism. Option (D): Incorrect. This describes epigenetics, which focuses on gene-environment interactions, not genomics. 

Step 3: Conclusion. 
The correct definition of genomics is the study of genes within an organism. \[ \therefore \text{The correct answer is: The study of genes within an organism.} \]
