검증된 단계별 안내1
Understand the role of telomerase: Telomerase is an enzyme that adds repetitive nucleotide sequences to the ends of chromosomes, known as telomeres, which protect the chromosome from deterioration.
Recognize the function of telomeres: Telomeres shorten with each cell division, and when they become too short, the cell can no longer divide and becomes senescent or dies.
Identify the impact of reduced telomerase activity: With little or no active telomerase, telomeres cannot be adequately maintained, leading to their progressive shortening.
Connect telomere shortening to cellular aging: As telomeres shorten, cells lose their ability to divide, which contributes to aging and the loss of cellular function.
Conclude the effect of reduced telomerase: Reduced telomerase activity leads to cellular aging and dysfunction, as cells can no longer maintain their telomeres, ultimately resulting in the loss of cell function.
