Telomeres Flashcards
(5 cards)
What is devil facial tumour disease (DFTD)
*A type of transmissible cancer, which causes tumours to form along the face region of tasmanian.
*This cancer can be spread just by direct contact
*These cells don’t age or die making cures difficult to find
What is senescence
Senescence is the process of cell aging to the point they aren’t able to divide any more
What is Telomeres
Telomeres are non coding DNA at the end of chromosomes, which protects them from damage during replication. Normally, during each cell division the telomeres get shorter until it’s too short and can’t be replicated again, so cells dies
Why is DFTD cells immortal
The cells of DFTD are immortal because their telomeres don’t shorten with each cell division
What is TRISOMY?
It is a type of mutation that occurs during meiosis, where a cell has three copies of a particular chromosome instead of the normal two.
