  2. Telomere - Wikipedia

    en.wikipedia.org/wiki/Telomere

    Telomere is a region of repetitive nucleotide sequences associated with specialized proteins at the ends of linear chromosomes (see Sequences). They are a widespread genetic feature primarily associated with eukaryotes organisms. In most species possessing telomeres, they protect the terminal regions of chromosomal DNA from

  3. Telomeric repeat–containing RNA - Wikipedia

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

    TERRA is an evolutionarily conserved long-non-coding RNA found in many nucleus-containing eukaryotic cells such as chicken (Gallus gallus domesticus), [1] humans (Homo sapiens), budding yeast (Schizosaccharomyces cerevisiae), fission yeast (Schizosaccharomyces pombe), mice (Mus musculus), zebrafish (Danio rerio), and various plants (Arabidopsis thaliana, et cetera).

  4. Telomerase - Wikipedia

    en.wikipedia.org/wiki/Telomerase

    Telomerase, also called terminal transferase, [1] is a ribonucleoprotein that adds a species-dependent telomere repeat sequence to the 3' end of telomeres. A telomere is a region of repetitive sequences at each end of the chromosomes of most eukaryotes .

    They then used α factor to block cells with induced short telomeres in late G1 phase and measured the change in telomere length when the cells were released under a variety of conditions. They found that when the cells were released and concurrently treated with nocodazole , a G2/M phase cell cycle inhibitor, telomere length increased for the ...

  6. Mega-telomere - Wikipedia

    en.wikipedia.org/wiki/Mega-telomere

    A telomere array is a unique arrangement of telomeres within a sample (cell, individual, etc.) that is defined by the number of sequence repeats, the pattern of fragments given by restriction digest, the chromosome on which it is found, and the specific location of the sequence on that chromosome.

  7. Subtelomere - Wikipedia

    en.wikipedia.org/wiki/Subtelomere

    In contrast, germ line and cancer cells possess an enzyme, telomerase, which prevents telomere degradation and maintains telomere integrity, causing these types of cells to be very long-lived. In humans, the role of subtelomere disorders is demonstrated in facioscapulohumeral muscular dystrophy (FSHD), Alzheimer's disease , epilepsy [ 17 ] and ...

  9. Eukaryotic DNA replication - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_DNA_replication

    The end replication problem is handled in eukaryotic cells by telomere regions and telomerase. Telomeres extend the 3' end of the parental chromosome beyond the 5' end of the daughter strand. This single-stranded DNA structure can act as an origin of replication that recruits telomerase.
