Describe the production and processing of a protein that will be exported from a eukaryotic cell. Begin with the separation of the messenger RNA from the DNA template and end with the release of the protein at the plasma membrane. Describe the steps of protein synthesis, beginning with the attachments of a messenger RNA molecule to the small subunit of a ribosome and ending with the release of the polypeptide from the ribosome. Include in your answer a discussion of how the different types of RNA function in this process. Select three of the following, and for each of the three that you have chosen, explain how the process of recognition occurs and give an example.
Organisms recognize others as members of their own species.
Antigens trigger antibody responses. Nucleic acids are complementary. Explain how the principles of gel electrophoresis allow for the separation of DNA fragments. Describe the results you would expect from the electrophoretic separation of fragments from the following treatments of the DNA segment above. Assume that the digestions occurred under appropriate conditions and went to completion.
