Chromosomes consist of two arms that extend out from a specialized region of DNA , called Centromere. Centromere or primary constriction gives a particular shape to chromosomes due to its position. The chromosome extremities or terminal regions on either side are called telomeres.

What is the medical definition of telomere?
A telomere in medical terminology means the end of a chromosome that is used to regenerate cells. Every time a cell dies the telomere regenerates the cell.
What is the tip of chromosome called?
telomere
What do you call the tip of a chromosome?
Telomere
Which part of chromosome exchange during meiosis centromere or telomere?
During meiosis, chromosome exchange occurs at the chiasmata, which are points of crossing over between non-sister chromatids. The exchange involves the exchange of genetic material between homologous chromosomes, not specifically at the centromere or telomere regions.
Explain telomere erosion and the role of telomerase?
Telomere erosion is the shortening of the protective caps at the end of chromosomes called telomeres, which occurs with each cell division and is associated with aging and cell senescence. Telomerase is an enzyme that helps to maintain telomere length by adding repetitive DNA sequences to the ends of chromosomes. It is particularly active in stem cells and cancer cells, allowing them to continue dividing without undergoing senescence or apoptosis.
Does the entire DNA replicate?
No, the telomere is shortened after each replication.
What do telomerase do?
enzyme that helps in sythesis and elongation of telomere length
What is the link between telomeres and aging?
Telomeres shorten with each cellular replication; telomere length is inversely proportional to age. While telomere extension does tend to make cells "young again", telomere extension is problematic for a treatment for age because many kinds of cancer replicate indefinitely due in part to the fact they have overactive telomerase, a protein that extends the telomeres. Until the link between cancer and telomeres is understood, telomere extension therapy will not be feasible.
What is a telomere amd how does it affect cloned animals?
After each cell division the telomere gets shorter, it's a marker of an old cell. It's present in eukaryotic cells as a stop signal for gene transcription.
What term describes a structure that protects the ends of a chromosome?
Telomere. Telomeres are repetitive DNA sequences located at the ends of chromosomes that help protect them from degradation and prevent the loss of genetic information during cell division.
Where is the diagnostics port on a Citroen DS5?
