Reverse transcriptase is an enzyme present in some of the virses which has the ability of
synthesizing a complementary DNA using an RNA molecule as a template.This process is called
reverse transcription.This is not possible by normal DNA polymerase because it is only possible
to make RNA from DNA,but not the vice versa,which is only possible by reverse
transcriptase.The retroviruses or RNA viruses contains RNA as their genetic material,so when
they infect a host genome,they use this RNA as a template to make a complementary DNA using
the host\'s transcriptional machinery and thus start replicating.Reverse transcriptase is mainly
present only in some viruses,not humans,but an exception is the telomere portion of a
chromosome in human and other organisms where enzyme telomerase is present which acts as a
reverse transcriptase.
