1. Compare the replication cycles of H1N1 and Herpes simplex. -Herpes (DNA) and H1N1 (RNA) viruses both multiply in the cells cytoplasm. The major differences among the multiplication process of these viruses lie in how MRNA and viral RNA are produced. The sequence is as follows (1 and 2) are: Entry, uncodeing the viral DNA/ RNA (replication). (3) Transcription of a portion of the viral DNA. Translation follows (resulting enzymes) for multiplication of DNA/RNA. Most cases of DNA viruses early transcription is carried with the host transcriptase (some types of RNA carry their own transcriptase.) (4) Then translation of the “late” viral gene occurs. (5) Synthesis of capsid proteins in the cytoplasm of the host cell. (6) Maturation of the viral DNA/RNA and capsid proteins assemble to form a complete virus from the host cell.
2. Explain how such a tremendous diversity of IGG’s can be produced by plasma cells in response to an equal diversity of antigens. -
Immunoglobulins are one of two important protein molecules of the immune system that engage in the recognition of pathogens or other foreign material. Antigen recognition is a pivotal process in the immune response. Antigen recognition allows the immune system to recognize each antigen with tremendous specificity in order to avoid an immune response to host tissues. One way in which the immune system accomplishes this is through the production of antibodies by the B-cell. Each antibody must be able to bind specifically to one part of an antigen; therefore a vast number of unique antibodies are required. The complex mechanism of antibody creation has been estimated to be able to produce billions of different structures which accounts for the widely effective function of these molecules. Take blood transfusions for example, the more transfusions one has the more antibodies you gain.
