Answer:
The correct option is : cells containing empty plasmid vectors
Explanation:
The blue-white screen is a technique which involves the rapid identification of the recombinant bacteria in a vector-based molecular cloning experiment. In this method, a DNA ligated vector is inserted in a host cell which is viable for transformation and grown in presence of X-gal.
The cells that are transformed with the vectors having the recombinant DNA produce the white colonies. Whereas, the cells transformed with empty vector i.e. the non-recombinant plasmids, produce the blue colonies.
Answer:
This way, for 20^2.55 = 2109 amino acids are require to have 2*1056 number different sequences.
Explanation:
Protein should contain 2*1056 of different sequence so
2*1056 = 20^x
Log (2*1056) = log 20^x
3.3246 = (x ) * 1.3010
X= 2.555
Answer:
It gets turned into sugars and nutrients so the plant can grow.
