Question

A times partial sequencing of cloned cDNAs is carried out. These cDNA are known as ___________

(a) expressed RNA sequences

(b) expressed sequence tags (ESTs)

(c) expressed cDNA sequences

(d) library

I have been asked this question in an interview for internship.

My doubt stems from cDNA Libraries, Polyadenylated RNA and cDNA Synthesis in division Libraries Construction of Genetic Engineering

Answer 1

The correct answer is (b) expressed sequence tags (ESTs)

Explanation: The partial sequencing of cloned cDNA is the first step of genome characterization project. These cloned cDNA sequences are known as expressed sequence tags (ESTs).
