Definition

A special type of enzyme that helps maintain the ends of chromosomes, known as telomeres, during cell division. It is important for the growth of certain cells, like stem cells and cancer cells.

Example

Telomerase plays a crucial role in the immortality of cancer cells by extending their telomeres.

Conversation

Have you heard about telomerase?

Yeah, I read it helps maintain the ends of chromosomes.

Exactly! It's fascinating how it works in stem cells and cancer cells.

I know, right? It seems like a key player in aging and cell division.

Synonyms & Antonyms

Root Explanation

Telomerase → It is formed from "telomere" (from Greek "telos", meaning end, and "meros", meaning part) and "-ase" (a suffix used in biochemistry to denote enzymes). The word "telomerase" refers to the enzyme that adds nucleotide sequences to the ends of chromosomes, known as telomeres, thus extending their length.

Memory Tip

Think of 'telomere' as the 'end part' of a chromosome, and '-ase' indicating an enzyme. This helps you remember that telomerase is the enzyme that works on the ends of chromosomes.
