Question

Which property of phage DNA makes it suitable for the insertion of foreign DNA fragments?

पर्याय

• Its RNA composition allows for reverse transcription of any gene

• Its circular structure allows for unrestricted insertion at any point

• Its protein coat protects foreign DNA from degradation

• Its linear structure contains various specific restriction enzyme sites

Answer 1

Phages typically contain linear DNA molecules that have various specific restriction enzyme sites. These sites allow foreign DNA fragments to be easily inserted into the phage genome, making them effective vectors for cloning purposes.
