The following are the features that are required to facilitate cloning into a vector.
Adjacent to a frequently-asked paragraph in the same chapter.
Match the following with their roles in recombinant DNA technology: Column I a) Palindromic sequence b) Taq polymerase c) Ti plasmid d) Ethidium bromide Column II 1. Plant gene transfer vector 2. Visualisation of DNA under UV 3. Sequence recognised by restriction enzyme 4. Enzyme for PCR amplification
Correct answer: B — a–3, b–4, c–1, d–2
Restriction enzymes cut palindromes, Taq polymerase amplifies DNA in PCR, Ti plasmid is plant vector, and EtBr stains DNA for UV detection.
