Those changes in an individuals' genotype that ensure genetic variation begin to be done in Metaphase, where chromosomes are aligned to the equatorial axis of the cell, and eventually, each chromosome is pulled to each pole of the cell during Anaphase I. After this process, follows telophase I, where we can say that each chromosome is given to each of the two daughter cells. We can say then that the creation of different versions of alleles begins with Telophase I.
 
        
             
        
        
        
Reverse transcriptase use mRNA to
form DNA apex
Reverse transcriptase is a broad
family of enzymes that play a unique role in the flow of genetic information. The
synthesis of DNA from an RNA template through reverse transcription produces
complementary DNA. Reverse transcriptase use an RNA template and a short
primer complementary to the 3' end of the RNA to direct the synthesis of the
first strand complementary DNA, which can be used directly as a template for
the Polymerase Chain Reaction.
