Sentences with phrase «dna called telomeres»

The myth has a kernel of truth, because the ends of chromosomes are protected by specialized stretches of DNA called telomeres.

The ends of chromosomes are capped by wads of DNA called telomeres.

Telomerase is an enzyme that replicates the ends of chromosomes (sections of DNA called telomeres), replacing the DNA lost when chromosomes are copied before cell division and, therefore, maintaining the stability of the genome.

Not exact matches

Austad recalls one conversation in which Muller made an insightful connection about telomeres, the DNA - and - protein caps at the ends of chromosomes that shorten with every cell division, eventually pushing cells into a nondividing state called senescence.

Greider and Hackett wondered whether short telomeres might render chromosomes vulnerable to a type of enzyme called an exonuclease, which degrades DNA.

Telomeres are composed of double - stranded DNA with terminal 3» single - stranded G - rich overhangs called telomere G - tails.

These tiny strips of DNA, called telomeres, cap the end of chromosomes.

DNA damage, including the shortening of chromosome endcaps (called telomeres) is also a prime suspect.

Their studies revealed that a subset of normal breast precursor cells, called luminal progenitors, have dangerously short telomeres and display a correspondingly high level DNA damage response localized at their chromosome ends.

There are various causes of senescence: Damage to the DNA is just as possible as is the attainment of a maximum number of divisions (limited by the so - called telomeres).

The suspected immortalizing agent is an enzyme called telomerase (tee - LOW - mer - ace) that adds DNA to the endcaps, or telomeres, of the cell's chromosomes.

This information is molecularly encoded at the end of each chromosome in a DNA structure called the telomere.

Scientists believe that the reason for these amazing benefits is due to something called telomeres, which are the caps at the end of each strand of DNA that protect our chromosomes.

A DNA molecule called a «telomere» protects the chromosome material from breaking down — but as we age, our telomeres can shorten.

In the Telomere Diagnostics lab at TeloYears, they measure the average telomere length (ATL) found in the DNA using a procedure called qPCR (quantified polymerase chain reaction), which is apparently a pretty accurate method of measuring telomere length and by far the most referenced in scientific litTelomere Diagnostics lab at TeloYears, they measure the average telomere length (ATL) found in the DNA using a procedure called qPCR (quantified polymerase chain reaction), which is apparently a pretty accurate method of measuring telomere length and by far the most referenced in scientific littelomere length (ATL) found in the DNA using a procedure called qPCR (quantified polymerase chain reaction), which is apparently a pretty accurate method of measuring telomere length and by far the most referenced in scientific littelomere length and by far the most referenced in scientific literature.
