A cell line described as immortalised

  • A.can divide indefinitely in culture
  • B.survives without any nutrient medium
  • C.has lost all of its chromosomes
  • D.cannot be frozen for later use

Answer: A

Escaping the normal replicative limit lets the line be maintained indefinitely, which is convenient but means it differs from the tissue it came from. Such lines often carry chromosomal abnormalities. Convenience is bought at the cost of resemblance to the original tissue.
