Question

a mutant cell loses parts of the ends of its chromosome every time it replicates what is the reason​

Answer 1

Telomeres are essential chromosomal structures that cap the ends of linear eukaryotic chromosomes. Incomplete DNA replication every time cells divide results in a gradual loss of telomeric sequences in human somatic tissues. Telomere erosion ultimately results in the loss of telomeric function, which in turn triggers the cells to enter a non-dividing but biochemically active state termed replicative senescence. Telomere-dependent replicative senescence is considered to have evolved as a tumor suppressive mechanism; indeed, 85% of human malignancies express the enzyme telomerase that synthesizes telomere repeat sequences, preventing telomere loss and facilitating unlimited cell division. Senescent cells have the potential to interfere with the tissue microenvironment, and the accumulation of senescent cells is considered to contribute to age-related tissue deterioration and disease. Consistent with this hypothesis, telomere loss is observed as a function of age in human tissue, and this loss has been linked to specific disease phenotypes.

Mark me as brilliant pls

Answer 2

Answer:

it's true

Explanation:

it's because cell wants to change it's characteristics every time it replicates

that's what mutation is...
