DNA Animal Viruses Animal viruses usually do not kill the cell. The viruses have a membranous outer envelope with spikes. The virus enters the cell by endocytosis. Nucleic acid is released inside the cell. It is transcribed and translated to produce more viral DNA, protein coats and spikes. The virus acquires its membrane when it is released from the cell by budding (exocytosis). The host cell is not necessarily killed. Click here for more details on viral reproduction in animal cells. Retroviruses The genetic material of retroviruses is RNA. The retrovirus carries an enzyme called reverse transcriptase , which is capable of creating a DNA copy of the viral RNA. The new DNA produced from the RNA template is called cDNA . DNA synthesis follows the production of cDNA to produce a double-helix.

Unformatted text preview: The DNA then becomes incorporated into the host DNA. The new viruses escape the host cell by budding. The AIDS virus (HIV) is an example of a retrovirus. Recombinant DNA Technology Vectors Vectors are DNA used to transfer genes into a host cell. A vector must be capable of self-replicating inside a cell. Marker genes can be used to determine if the gene has been taken up. Marker genes must have some distinguishable characteristic. For example if you put a gene that enables an ampicillin resistance on the same vector as the same vector as the gene for human insulin production, then any bacteria that grow on an ampicillin plate will be able to produce insulin....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
