Question:
A gene having non-coding introns and coding exons is known as :
A gene having non-coding introns and coding exons is known as :
Show Hint
Genes interrupted by non-coding introns between coding exons are called split genes.
Updated On: Oct 22, 2026
- Pseudogene
- Structural gene
- Split gene
- Oncogene
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Recall gene structure in eukaryotes:
In eukaryotes the coding part of a gene is broken into pieces.
The coding pieces are called exons and appear in the mature mRNA.
The non-coding pieces between them are called introns and are removed by splicing.
Step 2: Name the gene type:
Because the coding sequence is interrupted by introns, such a gene is called a split gene.
Step 3: Why the other options are wrong:
A pseudogene is a non-functional copy of a gene that has lost its ability to be expressed.
A structural gene codes for a protein, but this name does not say anything about introns.
An oncogene is a gene that can turn a normal cell into a cancer cell.
Final Answer:
A gene with introns and exons is a split gene, option (C).
