WELCOME TO TEACHERS AND CLASS 10X2! TEACHER: Dương Huỳnh Yến Linh Chapter III: VIRUS AND INFECTIVE DISEASE Lesson 29: STRUCTURE OF VIRUSES Lesson 29: STRUCTURE OF VIRUSES * Features of viruses How viruses compare to bacterial cells? (size, reproduce, made of cell) (A) (B) Figure: Relative size of bacteria and virus  very small and they measured in nanometers (kích thước siêu nhỏ đo nanomet) Lesson 29: STRUCTURE OF VIRUSES * Features of viruses Figure:Components of virus (a) and components of bacterial cell(b)  Viruses are not made of cells,(Virut khơng có cấu tạo tế bào) Viruses are made out of two basic components: coat and core (Có cấu tạo đơn giản gồm: vỏ & lõi) * Features of viruses  Virus need a host to reproduce  an obligate intracellular parasite (Virut nhân lên nhờ máy tổng hợp tế bào chủ  kí sinh nội bào bắt buộc) I STRUCTURE OF VIRUSES 1.Viruses are compose of what? What is capsid? (Coat) (core)  All viruses contain the following two basic components:( tất virus có thành phần bản) 1) CORE: Genetic material/nucleic acid (DNA or RNA) (lõi: vật liệu di truyền ADN ARN) 2) COAT: a protein shell that covers the genome known as capsid (vỏ prơtêin bao bọc bên ngịai axit nucleic, gọi capsid) What is capsid?  Capsid composed of proteinaceous subunits called capsomeres,(capsit cấu tạo từ đơn vị protein gọi capsome) Nucleocapsid What is Nucleocapsid?  Combination of the nucleic acid and capsit is called the nucleocapsid (phức hợp gồm axit nuclêic vỏ capsit gọi Nuclêôcapsit) I STRUCTURE OF VIRUSES  A layer of membrane called the envelope (some but not all viruses): a lipid bilayer and protein,spikes glycoproteins (Một số virut cịn có thêm vỏ ngồi cấu tạo gồm lipit kép prơtêin, gai glicôprêtin.) REVIEW Choose the best answer: Viral genome is a Single – stranded DNA b Single or double - stranded RNA c DNA or RNA (Single or double - stranded ) d All of these Homework - Learn and answer the question in your textbook - Reading lesson 30 and answer the following question: How viruses reproduce? How many steps are there in viral replication? How HIV infect? .. .Chapter III: VIRUS AND INFECTIVE DISEASE Lesson 29: STRUCTURE OF VIRUSES Lesson 29: STRUCTURE OF VIRUSES * Features of viruses How viruses compare to bacterial cells?
