What can result from unchecked chromosomal aberrations?

Unchecked chromosomal aberrations can lead to mutations or cancer due to the disruption of normal genomic integrity. Chromosomal aberrations include changes such as deletions, duplications, translocations, and inversions in chromosomes. When these alterations occur and are not adequately repaired or corrected by cellular mechanisms, they can cause significant changes in gene expression and cellular function.

Mutations may result from chromosomal rearrangements, potentially activating oncogenes or inactivating tumor suppressor genes, which can drive the transformation of normal cells into cancerous ones. The accumulation of such genetic changes over time, particularly in critical regulatory genes, can lead to uncontrolled cell growth and division, characteristic of cancer.

The other options, while they may relate to cellular processes, do not occur as consequences of unchecked chromosomal aberrations. Increased DNA repair processes typically happen in response to damage rather than as a direct outcome of aberrations. Cellular regeneration and normal cellular function are generally maintained in healthy cells, but they would be compromised in cells with significant chromosomal damage that leads to dysfunction or malignancy.
