What telomere means?

Definition of telomere : the natural end of a eukaryotic chromosome composed of a usually repetitive DNA sequence and serving to stabilize the chromosome.

Why do telomeres shorten?

Telomeres are subjected to shortening at each cycle of cell division due to incomplete synthesis of the lagging strand during DNA replication owing to the inability of DNA polymerase to completely replicate the ends of chromosome DNA (“end-replication problem”) (Muraki et al., 2012).

Where are the telomeres located?

ends of chromosomes
Telomeres are structures made from DNA sequences and proteins found at the ends of chromosomes. They cap and protect the end of a chromosome like the end of a shoelace. In almost all animals, from the simplest to the most complex, telomeres are required for cell division.

How do telomeres replicate?

Telomerase adds complementary RNA bases to the 3′ end of the DNA strand. Once the 3′ end of the lagging strand template is sufficiently elongated, DNA polymerase adds the complementary nucleotides to the ends of the chromosomes; thus, the ends of the chromosomes are replicated.

What does a telomere look like?

Telomeres consist of hundreds or thousands of repeats of the same short DNA sequence, which varies between organisms but is 5′-TTAGGG-3′ in humans and other mammals. Telomeres need to be protected from a cell’s DNA repair systems because they have single-stranded overhangs, which “look like” damaged DNA.

What is a telomere made of?

Telomeres are structures made from DNA sequences and proteins found at the ends of chromosomes. They cap and protect the end of a chromosome like the end of a shoelace.

How do I increase my telomeres?

Get enough sleep. Reduce or manage stress. Eat a telomere-protective diet full of foods high in vitamin C, polyphenols, and anthocyanins. Consume red peppers, kale, dark chocolate, and blueberries for a positive balance that protects DNA from stress.
