functional genomics {Ans: the study of the relationship between genes and their function}Amount of nucleotides lost per division {Ans: About 100. Adult cells can only divide under 50 times on average because of this, telomerase is inactive almost everywhere. Cells typically stop dividing when under 100 TTAGGG repeats are left. Telomerase reactivation has been associated with cancer.}factors of meiosis increasing genetic variability in offspring {Ans: random crossing over, orientation of bivalents during metaphase I}telophase I {Ans: separates 2 cells, immediately followed by cytokinesis and prophase II}CAR-T therapy {Ans: Engineering T cell "assassins" to recognize and kill cancer cells blood is removed from the patient, CAR gene is inserted, new car t cells grown (millions), reinserted back into patient}mutagens {Ans: increase the likelihood of mutations in DNA at certain points (radiation, chemicals, smoking)}Types of DNA polymerase II proofreading methods {Ans: Mismatch repair Base excision repair Nucleotide excision repair}Taq polymerase {Ans: heat-tolerant up to 95°C comes from thermus aquaticus}mitotic spindle {Ans: a structure made of microtubules that controls chromosome movement during mitosis}kinetochores {Ans: The structures on sister chromatids where microtubules attach 1) some microtubules attach directly and pull 2) some k.c are
