Answer #1

Long, repetitive DNA sequences found at the end of linear eukaryotic chromosomes.

telomeres are long repetitive sequences found at the end of chromosomes.

They shorten after every cell division.

Telomeres consist of stretches of repetitive DNA sequences at the ends of chromosomes. These are progressively shortened with each mitosis until cells become senescent at a critical minimal length. Telomerase is a reverse transcriptase that stabilizes telomere length.
