• Derived from mRNA → cDNA
Updated On: May 13, 2026
- Eukaryotic Sequencing Technology
- Expressed Sequence Tag
- Eukaryotic Sequence Test
- Eukaryotic Sequence Tag
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
EST (Expressed Sequence Tag) refers to short DNA sequences obtained from expressed genes (mRNA). These sequences represent portions of actively transcribed genes.
• Derived from cDNA libraries
• Used for gene identification and mapping
Step 1: Analyzing each option.
