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.

It is equivalent to the consumption of one ton of ice per day and originated during the transition from stored natural ice to mechanical refrigeration. A refrigeration ton is approximately equivalent to 12,000 BTU / h or 3.517 kW.Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in tons (of refrigeration). Many manufacturers also specify capacity in BTU / h, especially when specifying the performance of smaller equipment.t is equivalent to the consumption of one ton of ice per day and originated during the transition from stored natural ice to mechanical refrigeration.
