MCQ

Question

For successful transfer of a foreign gene from the engineered Ti-plasmid to the plant genome, few cis-acting DNA elements and trans-acting protein factors are very much essential. Select the CORRECT combination from the following

Options

Choose one · Correct answer highlighted

Opine catabolism genes, Left border sequence, Right border sequence Opine catabolism genes, Left border sequence, Virulence genes Hormone biosynthetic genes, Right border sequence, Virulence genes Left border sequence, Right border sequence, Virulence genes Correct

Explanation

This outcome reflects DNA replication fidelity, where polymerase proofreading and origin firing ensure accurate duplication. Option D captures this correctly because it matches high-fidelity synthesis mechanisms, consistent with textbook descriptions and experimental observations in molecular biology.
