We are able to manipulate genes through genetic engineering because -
- ABy observing DNA through microscope we can delete or insert gene by using enzymes of eukaryotic cell
- BRestriction endonucleases can be isolated from prokaryotic cells and these can be used as molecular scissor
- CDNAase I helps in cutting of DNA at specific locations
- DWe are able to introduce foreign DNA into the host cell without any vector or device
