Yes, telomeres can be lengthened through the activation of telomerase, the enzyme responsible for adding repetitive DNA sequences to the telomeres. In laboratory settings, researchers have been able to lengthen telomeres by introducing telomerase into cells. However, this process is complex and carries risks, including the potential for encouraging cancerous growth. While telomeres can be lengthened in experimental conditions, safely and effectively increasing telomere length in humans is still an area of active research.
