How can a gene that contains introns be made shorter for genetic engineering purposes? What does it use and how does it use it?

reverse transcriptase to reconstruct the gene from its mRNA

Explanation:

Genetic engineering may be defined as the process of using the recombinant DNA (rDNA) technology in order to alter the genetic makeup of the organism. It is also called as the genetic modifications. It uses the science of biotechnology to modify and manipulate the genes of an organism.

A gene containing introns can be made shorter and still remain functional for the genetic engineering purposes by using the reverse transcriptase for reconstructing the gene from the mRNA.

It uses the reverse transcriptase of the mRNA.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

whats the answer to your question?
