If a researcher introduces a telomerase inhibitor to cells undergoing division in vitro, which consequence follows for chromosome stability?

💡 Explanation

Telomerase is responsible for maintaining telomere length. Introducing a telomerase inhibitor will cause progressive telomere shortening during cell division, because the cell lacks the enzyme to replenish the telomere sequence; therefore, chromosomal instability increases, rather than the other protective or mutative outcomes.

• If a retinal detachment separates photoreceptors from the retinal pigment epithelium (RPE), which consequence follows, hindering vision?
• A researcher investigates rheumatoid arthritis. If TNF-α secretion in the synovium is chronically elevated despite conventional treatment, which consequence is most likely?
• During intense exercise, why does hemoglobin's oxygen-binding affinity decrease in muscle tissue capillaries where both carbon dioxide and lactic acid concentrations are elevated?
• If a 60-year-old individual with developing presbyopia views objects at varying distances, why do near objects appear blurry compared to distant objects?
• A patient with a genetic mutation produces abnormal fibrinogen. If this patient experiences a cut, which consequence follows?
• Why does administering antipyretics, such as acetaminophen, to a patient with a fever reduce body temperature rather than just suppressing shivering?
