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.

It means an organism respire without it
so that organism know as anaerobic
for example : bacteria eats human and animal dead bodies under the earth there O² is deficient so bacteria respire with oxygen O²
The answer is; Dead Zone
These areas have anoxic condition means they have very little to zero dissolved oxygen hence cannot support marine/aquatic life. This is as a result of eutrophication caused by algae blooms. This phenomenon is brought about by pollution of these water reservoirs. These algae bloom take up all the oxygen in the water during their mass decomposgion hence leave no dissolved oxygen for the rest of the marine life.
