It is for this reason that is referred to as a complementary DNA or cDNA. Though there are numerous processes for synthesizing cDNA, the best way of doing so is by using mature or fully spliced mRNA. This is usually done by using the enzyme reverse transcriptase.
Ammonia is used as refrigerant prominently in the refrigeration systems of food industry like dairies, ice creams plants, frozen food production plants, cold storage warehouses, processors of fish, poultry and meat and number of other applications.
A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle.n explosion could result from refrigerant-type compressor lubricating oils being compressed together with the air. Air is so frequently used as a coolant that air cooling is seldom mentioned in this context. Due to the low boiling point of its constituents, air is less often used as a refrigerant.
