Question

Which one of the recombinant DNA techniques is almost obsolete?

• A. Long DNA synthesis
• B. DNA sequencing
• C. Polymerase Chain Reaction
• D. cDNA cloning

Hint:

Consider the advancements in molecular biology techniques that have replaced traditional methods.

Answer 1

The Correct Option is D

cDNA cloning, once widely used to study gene expression and create recombinant DNA, has largely been replaced by modern techniques like high-throughput sequencing and RNA-seq. These advanced methods provide more comprehensive and efficient analysis of transcriptomes.
