LIFESCI 3 Lecture Notes - Lecture 9: Okazaki Fragments, Dna Replication, Telomere
Document Summary
Ls 3 - lecture #9 - end replication problem & telomeres. Clicker question: dna ligases repair nicks in dna where: O(cid:374)e e(cid:374)d is a 5" phosphate a(cid:374)d the other a 3" phosphate. O(cid:374)e e(cid:374)d is a 5" h(cid:455)dro(cid:454)(cid:455)l a(cid:374)d the other a 3" phosphate. O(cid:374)e e(cid:374)d is a 5" h(cid:455)dro(cid:454)(cid:455)l a(cid:374)d the other a 3" h(cid:455)dro(cid:454)(cid:455)l. O(cid:374)e e(cid:374)d is a 5" phosphate a(cid:374)d the other a 3" h(cid:455)dro(cid:454)(cid:455)l. Midterm #1 will be this friday february 2. Only material covered in the study guide posted on ccle will be covered on the exam. Encouraged to review clicker questions and lecture slides/notes. Especially clicker questions, sometimes they are recycled on exams. Exam is 80-90 questions, mostly multiple choice but also matching and. Every time dna is replicated, a little bit of information at the end of the chromosome is lost. Clicker question:in contrast to linear dna, circular dna replication typically: Occurs only at a single replication fork.
