Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding cDNA library construction.
cDNA libraries are constructed by reverse transcription of mRNA from a specific organism. Yeast is commonly used for this process due to its ability to express eukaryotic genes.
Step 2: Analyzing the options.
(A) yeast: Correct. Yeast is commonly used to construct cDNA libraries due to its ability to express genes effectively.
(B) cyanobacteria: Incorrect. While cyanobacteria have been studied for gene expression, they are not the primary organisms for constructing cDNA libraries.
(C) virus: Incorrect. Viruses are not typically used for constructing cDNA libraries.
(D) bacteria: Incorrect. While bacteria are used in genetic engineering, yeast is more commonly used for constructing cDNA libraries.
Step 3: Conclusion.
The correct answer is (A) yeast, as yeast is commonly used for constructing cDNA libraries.
cDNA libraries are constructed by reverse transcription of mRNA from a specific organism. Yeast is commonly used for this process due to its ability to express eukaryotic genes.

(A) yeast: Correct. Yeast is commonly used to construct cDNA libraries due to its ability to express genes effectively.
(B) cyanobacteria: Incorrect. While cyanobacteria have been studied for gene expression, they are not the primary organisms for constructing cDNA libraries.
(C) virus: Incorrect. Viruses are not typically used for constructing cDNA libraries.
(D) bacteria: Incorrect. While bacteria are used in genetic engineering, yeast is more commonly used for constructing cDNA libraries.
Step 3: Conclusion.
The correct answer is (A) yeast, as yeast is commonly used for constructing cDNA libraries.
