<u>A colony is a territory under the complete political and military control of the settlers of a state, which is distinct from the home territory of the sovereign.</u>
When the dsDNA copies are then inserted into vectors and cloned into E. coli. the scientist has produced a cDNA library.
A collection of DNA fragments that have been cloned into vectors to identify and isolate desired DNA fragments is known as the DNA library. cDNA libraries and genomic libraries are the two types of libraries.
cDNA (Complementary DNA )library: cDNA is a DNA copy of an mRNA molecule that is produced by reverse transcriptase, a DNA polymerase that can use RNA or DNA as its template.
- These are made by using mRNA as their starting material as templates.
- They only represent genes in the genome that are expressed under particular conditions.
- Because cDNA lacks introns, prokaryotic cells can express it.
