  2. Reverse transcriptase - Wikipedia

    en.wikipedia.org/wiki/Reverse_transcriptase

    A reverse transcriptase (RT) is an enzyme used to convert RNA genome to DNA, a process termed reverse transcription.Reverse transcriptases are used by viruses such as HIV, COVID-19, 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 chromosomes.

  3. Retroposon - Wikipedia

    en.wikipedia.org/wiki/Retroposon

    Retroposition accounts for approximately 10,000 gene-duplication events in the human genome, of which approximately 2-10% are likely to be functional. [5] Such genes are called retrogenes and represent a certain type of retroposon.

  4. Multicopy single-stranded DNA - Wikipedia

    en.wikipedia.org/wiki/Multicopy_single-stranded_DNA

    Since nearly all RT genes function in retrovirus replication and/or the movement of transposable elements, it is reasonable to imagine that retrons might be mobile genetic elements, but there has been little supporting evidence for such a hypothesis, save for the observed fact that msDNA is widely yet sporadically dispersed among bacterial ...

  5. Endogenous retrovirus - Wikipedia

    en.wikipedia.org/wiki/Endogenous_retrovirus

    An immunosuppressed condition could potentially permit a more rapid and tenacious replication of viral DNA, and would later have less difficulty adapting to human-to-human transmission. Although known infectious pathogens present in the donor organ/tissue can be eliminated by breeding pathogen-free herds, unknown retroviruses can be present in ...

  6. Bacterial transcription - Wikipedia

    en.wikipedia.org/wiki/Bacterial_transcription

    Bacterial transcription is the process in which a segment of bacterial DNA is copied into a newly synthesized strand of messenger RNA (mRNA) with use of the enzyme RNA polymerase. The process occurs in three main steps: initiation, elongation, and termination; and the result is a strand of mRNA that is complementary to a single strand of DNA.

  7. Recombinase - Wikipedia

    en.wikipedia.org/wiki/Recombinase

    In humans, over- or under-expression of Rad51 occurs in a wide variety of cancers. During meiosis Rad51 interacts with another recombinase, Dmc1, to form a presynaptic filament that is an intermediate in homologous recombination. [9] Dmc1 function appears to be limited to meiotic recombination. Like Rad51, Dmc1 is homologous to bacterial RecA.

  8. List of recombinant proteins - Wikipedia

    en.wikipedia.org/wiki/List_of_recombinant_proteins

    The following is a list of notable proteins that are produced from recombinant DNA, using biomolecular engineering. [1] In many cases, recombinant human proteins have replaced the original animal-derived version used in medicine.

  9. Restriction modification system - Wikipedia

    en.wikipedia.org/wiki/Restriction_modification...

    The RM system was first discovered by Salvatore Luria and Mary Human in 1952 and 1953. [1] [2] They found that a bacteriophage growing within an infected bacterium could be modified, so that upon their release and re-infection of a related bacterium the bacteriophage's growth is restricted (inhibited; also described by Luria in his autobiography on pages 45 and 99 in 1984).
