Telomeres and Telomerase02:41

Telomeres and Telomerase

28.1K
In eukaryotic DNA replication, a single-stranded DNA fragment remains at the end of a chromosome after the removal of the final primer. This section of DNA cannot be replicated in the same manner as the rest of the strand because there is no 3’ end to which the newly synthesized DNA can attach. This non-replicated fragment results in gradual loss of the chromosomal DNA during each cell duplication. Additionally, it can induce a DNA damage response by enzymes that recognize single-stranded...

Replication in Eukaryotes

18.4K
In eukaryotic cells, DNA replication is highly conserved and tightly regulated. Multiple linear chromosomes must be duplicated with high fidelity before cell division, so there are many proteins that fulfill specialized roles in the replication process. Replication occurs in three phases: initiation, elongation, and termination, and ends with two complete sets of chromosomes in the nucleus.

Replicative Cell Senescence02:15

Replicative Cell Senescence

4.5K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

Chromatin Packaging01:32

Chromatin Packaging

20.0K
Each human somatic cell contains 6 billion base pairs of DNA. Each base pair is 0.34 nm long, meaning each diploid cell contains a staggering 2 meters of DNA. This long DNA strand is packed inside a nucleus measuring only 10-20 microns in diameter with the help of specialized DNA-binding proteins called histones. Together they form a compact DNA-protein complex called chromatin. The chromatin is further compacted into higher-order structures. The highest level of compaction is achieved during...

    Summary

    Young elite athletes exhibit longer leukocyte telomeres (LTL) compared to inactive individuals, suggesting intense exercise may preserve telomere length. Further studies are needed to explore age-related effects in athletes.

    Area of Science:

    • Molecular Biology
    • Exercise Physiology
    • Gerontology

    Background:

    • Moderate physical activity is linked to slower telomere shortening.
    • The impact of high-intensity exercise, like elite sports, on telomere length is less understood.
    • Leukocyte telomere length (LTL) is a biomarker of cellular aging.

    Purpose of the Study:

    • To compare LTL between young elite athletes and physically inactive controls.
    • To investigate the relationship between elite athletic status and telomere length.

    Main Methods:

    • Analysis of variance (ANOVA) was used to compare LTL.
    • Study groups included young elite athletes (n=61) and healthy inactive controls (n=64).
    • Demographic data on sex and age were collected for both groups.

    Main Results:

    • Elite athletes demonstrated significantly longer LTL than control subjects (P = .013).
    • Average LTL was 0.89 ± 0.26 in athletes versus 0.78 ± 0.31 in controls.
    • No significant differences in LTL were found based on sex (P = .995) or age (P = .114) within this young cohort.

    Conclusions:

    • Young elite athletes possess longer telomeres compared to their sedentary counterparts.
    • Findings suggest high-level physical activity may be associated with preserved telomere length.
    • Future research should examine LTL across diverse age groups of elite athletes and compare them with both active and inactive individuals.
