The TERT gene provides instructions for making a component of the telomerase enzyme.
Understanding Telomerase and the TERT Gene
Telomerase is a crucial enzyme that maintains telomeres, which are protective structures found at the ends of chromosomes. These telomeres prevent chromosomes from sticking together or degrading. The TERT gene plays a key role in this process.
Role of the TERT Gene
- The TERT gene encodes a component of the telomerase enzyme.
- This enzyme is essential for maintaining the length and integrity of telomeres.
- Telomeres protect chromosomes from damage and degradation.
Telomeres and Chromosome Protection
Telomeres are repetitive DNA sequences located at the ends of chromosomes. They function to:
- Prevent chromosomes from fusing with each other.
- Protect DNA from degradation during cell division.
Without telomerase, telomeres would shorten with each cell division, eventually leading to cell aging or death.
