MBG 1000 Lecture Notes - Lecture 28: Cell Membrane, Rhinovirus, Aneuploidy
Document Summary
Midterm 1 (10-15 marks: central dogma, mutations (point mutations, hypo- & hypermorphic alleles, pedigree. Midterm 2 (10-15 marks: pedigrees, chromosome number (aneuploidy & polyploidy, meiosis, meiotic disjunction/non-disjunction. After midterm 2 lecture 23 to end (40-45 marks) Cells break > lysis: lytic cell life, rhinovirus (common cold) Enveloped viruses: form petrusions in plasma membrane, release of virus molecules that have a plasma membrane (enveloped, cells do not break, no lysis, lysogenic life cycle, reproduce more viruses without breaking open the cell. Stay within host for long period of time and make a lot of virus particles without being detected. Infects skin and mucus membrane cells: spread through skin to skin contact. >200 types of hpv; responsible for variety of warts. Most infections (~80%) clears in 1-2 years: low-risk type virus strains causes warts, two high-risk type viral hpv strains are primary risk factors for cervical cancer; causes. >75% of all cervical cancer cases: affects both male and female.
