Telomeres are made of _____ and _____.

Telomeres are made of repetitive DNA sequences and associated proteins.

The repetitive DNA sequences consist of short tandem repeats, typically composed of the sequence TTAGGG in humans, repeated several thousand times. These sequences are crucial for protecting the chromosome ends from degradation and preventing the loss of genetic material during cell division.

The associated proteins, often referred to as the shelterin complex, bind to the telomere DNA and help maintain its structure, stabilize the chromosome ends, and regulate telomere length.
