5. Telomere- it is a structure that keep a chromosomes from accidentally connecting to each other Okazaki fragment- it is a short fragment of DNA that is created on the lagging strand DNA ligase- “Stiches” the Okazaki fragments together Telomerase- it is an enzyme that adds telomere repeat sequences to the three prime end of DNA strands Cancer- mutation of cells Cloning- If cloned your clone will have shorter telomeres than you this could result in a short life for the clone. Aging- gets older
