Conference: Telomerase, aging & cancer Flashcards
short thymine-guanine sequence, replication and stability of the chromosome
Telomere
adenine-thymine Base pairs, attachment site of mitotic spindles
Centromere
this requires RNA primers attaching ahead on the lagging strand
synthesis of Okazaki Fragments
this state limits the replicative capacity of cells, thus preventing the proliferation of cells
a state of irreversible growth arrest (cellular senescence)
period of little proliferation
phase 1 of cellular senecence
rapid proliferation and cells divide in culture
phase 2 of cellular senecence
cells start dividing slower, and gradually proceeds a complete stop
phase 3 of cellular senecence
limit of cellular replicative capacity, that amounts to 50 divisions only
hayflick limit
mechanism where RNA primers start DNA replication
telomeric shortening
results of a sugar reducing molecule, such as fructose or glucose bonding to protein
glycation
transglutaminase (tTGase) mediated macromolecule crosslinking of histone
Crosslinking
what stabilizes the telomere
T-LOOP NIGGA
how can telomerase be used to extend cellular life span
RNA + hTERT gene product, they could immortalize cells without turning them cancerous
