  1. Telomerase reverse transcriptase (abbreviated to TERT, or hTERT in humans) is a catalytic subunit of the enzyme telomerase, which, together with the telomerase RNA component (TERC), comprises the most important unit of the telomerase complex. Telomerases are part of a distinct subgroup of RNA-dependent polymerases.

    What is reverse transcriptase?
    Definition of Reverse Transcriptase. It is needed for function in viruses, eukaryotes and prokaryotes. Reverse transcriptase enzymes in cells are involved in genetic diversity and in the process of aging in eukaryotic cells. In viruses, reverse transcriptase allows the virus to insert its DNA to the host cell's DNA,...

    What would happen if there was no reverse transcriptase enzyme?
    Reverse-transcribing DNA viruses, such as the hepadnaviruses, can allow RNA to serve as a template in assembling and making DNA strands. HIV infects humans with the use of this enzyme. Without reverse transcriptase, the viral genome would not be able to incorporate into the host cell, resulting in failure to replicate.

    What is the function of the enzymes in reverse transcription?
    The enzymes are encoded and used by viruses that use reverse transcription as a step in the process of replication. Reverse-transcribing RNA viruses, such as retroviruses, use the enzyme to reverse-transcribe their RNA genomes into DNA, which is then integrated into the host genome and replicated along with it.

    A reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. Reverse transcriptases are used by viruses such as HIV and hepatitis B to replicate their genomes, by retrotransposon mobile genetic elements to proliferate within the host genome, and by eukaryotic cells to extend the telomeres at the ends of their linear …

    • Reverse transcriptase is an RNA-dependent DNA polymerase that was discovered in many retroviruses such as human immunodeficiency virus (HIV) and avian myeloblastosis virus (AMV) in 1970. The reverse transcriptase catalyzes the conversion of RNA template molecules into a DNA double helix and provides a very useful tool for molecular biology research...
