Answer:
complementary DNA (cDNA)
Explanation:
The complementary DNA (cDNA) is a region of DNA that is synthesized from an RNA template by using a reverse transcriptase enzyme. cDNA is usually used to clone genes from eukaryotic organisms in prokaryotes. cDNA cloning is a technique that consists of isolating and amplifying a self-replicating prokaryotic organism that includes in its genome a cDNA of interest. This technique enables the insertion of fragments of eukaryotic DNA (cDNA) into plasmids that subsequently are multiplied by cloning and finally sequenced.
The secondary structure is responsible for the shape that the nucleic acid assumes. The bases in the DNA are classified as purines and pyrimidines. ... A purine base always pairs with a pyrimidine base (guanine (G) pairs with cytosine (C) and adenine (A) pairs with thymine (T) or uracil (U)).
Nitrogen fixation is the process where atmospheric nitrogen is converted by bacteria into biologically usable forms.
plant can not take nitrogen directly from the leaves.
DNA in prokaryotes are not bounded by Nuclear Memberane !! It is scattered all over cytoplasm !!
