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.
Just divid the distance by time
Genes and DNA of their parents i think its those two <span />
A species could gain negative traits through evolution. So, evolution does not always mean progress.
