Collection of

cDNA (complementary DNA) - cDNA fragments placed in the chambers, eg bacterial E. coli. cDNA is a mapping o f mRNA. In eukaryotic cells introns are not present in prokariotĂ łw. Therefore, in order to introduce the DNA of bacteria eurariot yczne to remove introns. mRNA is no longer sekwancja coding, which does not contain unnecessary information. Komplamentarny need to create the DNA to mRNA. Then, mRNA is separated and no longer take part in further steps.
