During the purification process for recombinant DNA technology, addition of chilled ethanol precipitates out
- Polysaccharides
- RNA
- DNA
- Histones
The correct answer is 3) DNA. During the purification process for recombinant DNA technology, addition of chilled ethanol precipitates out DNA.
The first step in recombinant DNA technology is the isolation of genetic material which is DNA in majority of the organisms. On addition of chilled ethanol, purified DNA precipitates out. It can be seen as collection of fine threads in the suspension which can be removed by spooling.
