Biotechnology Process: Key Concepts — NEET Biology
📚 Practice ConceptDescribe briefly the following: (a) Origin of replication (b) Bioreactors (c) Downstream processing
Which of the following integrated statements are correct regarding recombinant DNA construction? 1. Linking a gene with origin of replication ensures multiplication in host cells . 2. Restriction enzymes cut DNA at random non-specific sites . 3. Ligase joins foreign DNA to plasmid vector 4. Transformation requires competent host cells, often prepared by CaCl₂ and heat shock . 5. Downstream processing refers to separation and purification of recombinant protein .
View solution & NCERT explanation
Correct answer: C — 1, 3, 4, 5
Restriction enzymes cut DNA at specific palindromic sites, not random ones. All other steps (ori-linked replication, ligase action, transformation, and downstream purification) are correct integrations of principles, tools, and processes.
