Experts consider telomeres —
the protective ends of chromosomes — when calculating this age difference.
Unregulated growth is due in large part to the fact that tumor cells can rebuild
protective ends of their chromosomes, which are made of repeated DNA sequences and proteins.

protective caps
of DNA that prevent damage to the
ends of chromosomes.

protective caps at the
ends of chromosomes — than those raised in rural environments, researchers find.
ZBTB48 binds through the last
of its 11 zinc fingers directly to telomeric DNA (TTAGGG, in red) as well as subtelomeric variant repeats (TTGGG / TCAGGG, grey), which represent the
protective caps at the
end of chromosomes.
In vertebrates, telomeres act as
protective caps located at the
ends of chromosomes.
These DNA repeats are part
of the
protective capping structures, termed «telomeres,» which safeguard the
ends of chromosomes from unwanted and unwarranted DNA rearrangements that destabilize the genome.

of DNA that sit on the
ends of the
chromosomes in each cell like
protective caps.
Scientists at King's College London have found that people who have previously suffered from acne are likely to have longer telomeres (the
protective repeated nucleotides found at the
end of chromosomes) in their white blood cells, meaning their cells could be better protected against aging.
Telomeres are stretches
of protective, repetitive nucleotide sequences at the
ends of chromosomes.
Researchers found she had prematurely shortened telomeres,
protective caps on the
ends of chromosomes that reduce with age.
They also measured HDL cholesterol, cardiorespiratory fitness, lung function and the length
of the telomeres —
protective caps at the
end of chromosomes that have been found to shorten with age.
They form
protective caps at the
ends of linear
chromosomes to prevent chromosomal instability.
Human cells have been rejuvenated by delivering RNA encoding a protein that extends telomeres,
protective caps on the
ends of chromosomes that are associated with ageing and disease.

of telomeres,
protective cap - like protein complexes at the
end of chromosomes that ultimately affect the susceptibility to colds in middle - aged adults.
The researchers found a correlation between the stressful male reproductive strategy and a shortening
of their telomeres, which are
protective DNA caps at the
end of chromosomes.
LA JOLLA, CA — Rapidly dividing cancer cells are skilled at patching up damage that would stop normal cells in their tracks, including wear and tear
of telomeres, the
protective caps at the
end of each
chromosome.
Discovered in 1938 by geneticist Hermann J. Müller, telomeres (Greek for «
end part») are essentially
protective caps composed
of short DNA sequences on the tips
of chromosomes.
Both aspects center on the critical role
of telomeres,
protective caps on the
ends of chromosomes that erode with age.
The enzyme telomerase maintains the length
of telomeres, the
protective ends on
chromosomes, and most cancer cells use large amounts
of the enzyme to ensure their immortality.
This exhaustion
of proliferative potential, called senescence, can be triggered when telomeres — the
ends of linear
chromosomes - can not fulfil their normal
protective functions.
LA JOLLA — Ever since researchers connected the shortening
of telomeres — the
protective structures on the
ends of chromosomes — to aging and disease, the race has been on to understand the factors that govern telomere length.
Meditation also helps to protect our telomeres, the
protective caps at the
end of our
chromosomes.
Well, science suggests that a regular meditation practice can help lower our stress levels, thus increasing the length
of our telomeres — the
protective structures at the
end of our
chromosomes.
The answer is via the little
protective caps on the
ends of the
chromosomes inside your cells.
There's also evidence it accelerates aging by shortening telomeres — these are
protective caps at the
end of chromosomes, our body's basic genetic material.
A: Telomeres are the
protective caps on the
ends of each
of your
chromosomes, in each
of your body's cells.
