  2. Telomerase reverse transcriptase - Wikipedia

    en.wikipedia.org/wiki/Telomerase_reverse...

    Telomerase is a ribonucleoprotein polymerase that maintains telomere ends by addition of the telomere repeat TTAGGG. The enzyme consists of a protein component with reverse transcriptase activity, encoded by this gene, and an RNA component that serves as a template for the telomere repeat.

  3. Telomerase RNA component - Wikipedia

    en.wikipedia.org/wiki/Telomerase_RNA_component

    Telomerase RNA component, also known as TR, TER or TERC, is an ncRNA found in eukaryotes that is a component of telomerase, the enzyme used to extend telomeres. [ 3 ] [ 4 ] TERC serves as a template for telomere replication ( reverse transcription ) by telomerase.

  4. Telomerase - Wikipedia

    en.wikipedia.org/wiki/Telomerase

    The role of telomeres and telomerase in cell aging and cancer was established by scientists at biotechnology company Geron with the cloning of the RNA and catalytic components of human telomerase [9] and the development of a polymerase chain reaction (PCR) based assay for telomerase activity called the TRAP assay, which surveys telomerase ...

    en.wikipedia.org/wiki/Thomas_Cech

    Telomeres are shortened with every duplication of DNA, and must be lengthened again. He studies telomerase , the enzyme that copies the telomeric sequences and lengthens them. [ 8 ] The active site protein subunits of telomerase comprise a new class of reverse transcriptases , enzymes previously thought to be restricted to viruses and ...

  6. Telomeric repeat–containing RNA - Wikipedia

    en.wikipedia.org/wiki/Telomeric_repeat...

    TERRA-Telomerase Interaction at Long Telomeres. At cells with long telomeres, TERRA is proposed to act as a negative regulator of telomerase activity. This direct inhibitor function acts through base-pairing of the tandem repeats found throughout TERRA's 3'-end to the complementary RNA template region of telomerase. [6]

  7. Relationship between telomeres and longevity - Wikipedia

    en.wikipedia.org/wiki/Relationship_between...

    Telomeres at the end of a chromosome. The relationship between telomeres and longevity and changing the length of telomeres is one of the new fields of research on increasing human lifespan and even human immortality. [1] [2] Telomeres are sequences at the ends of chromosomes that shorten with each cell division and determine the lifespan of ...

  9. Transcription (biology) - Wikipedia

    en.wikipedia.org/wiki/Transcription_(biology)

    Some eukaryotic cells contain an enzyme with reverse transcription activity called telomerase. Telomerase carries an RNA template from which it synthesizes a telomere, a repeating sequence of DNA, to the end of linear chromosomes. It is important because every time a linear chromosome is duplicated, it is shortened.
