Telomerase is also known as terminal transferase.
Here's a breakdown:
Telomerase is a critical enzyme with a unique function:
- Function: It adds repetitive DNA sequences to the ends of chromosomes, known as telomeres. This process helps to maintain the stability and integrity of chromosomes, which are vital for cell division and survival.
- Structure: As described in the reference, telomerase is a ribonucleoprotein, meaning it's a complex of RNA and protein. This composition allows it to carry out its complex function of extending telomeres.
- Why it's called terminal transferase: The name "terminal transferase" directly reflects its function. It transfers the repetitive sequences to the terminal (end) of the chromosome.
| Term | Description |
|---|---|
| Telomerase | Enzyme that maintains telomeres by adding repetitive DNA sequences. |
| Terminal Transferase | An alternative name for telomerase, highlighting its activity at the chromosome ends. |
| Telomere | Repetitive DNA sequence at the ends of chromosomes, protected by telomerase. |
Therefore, terminal transferase is an accurate and descriptive alternate name for telomerase. This dual naming highlights the crucial role of this enzyme in chromosome stability.
