Telomere

  "id": "MLC-T-CHM-011846",
  "term": "Telomere",
  "field": "Chemistry",
  "definition": "A region of repetitive nucleotide sequences located at each end of a linear chromosome, protecting it from degradation or fusion with other chromosomes. In vertebrates, the sequence consists of multiple repeats of TTAGGG. During cell division, these terminal sequences shorten, a process linked to cellular aging; the enzyme telomerase can add telomeric DNA sequences back to the ends of chromosomes, and its activity is a subject of analytical measurement in cancer and aging research.",
