Question

Where is a gene located?

Hint:

Think of it like an address: Nucleus $\rightarrow$ Chromosome $\rightarrow$ DNA strand $\rightarrow$ Gene (Locus).

Answer 1

Step 1: Understanding the Concept:
Genes are the fundamental physical and functional units of heredity.

Step 2: Detailed Explanation:
A gene is a specific sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein.
DNA is tightly coiled and packaged into structures called chromosomes. Therefore, genes are arranged linearly along the length of chromosomes, which reside in the nucleus of eukaryotic cells.
The specific physical location of a gene on a chromosome is called its locus.

Step 3: Final Answer:
Genes are located on chromosomes.
