4.2 (84 reviews) (a) Identify both the cellular component and the location of the component that is responsible for producing the luciferase protein from mRNAs transcribed in the plasmid-containing T lymphocytes. Explain what dictates to the lymphocytes the correct order in which amino acids should be linked to form the luciferase protein. It can disturb the production of proteins, which could be crucial to the cell's survival. Or, for example, mutations in the signal transduction pathway can prevent the cell from regulating its cell cycle. When the cell cycle is unregulated, it can result in unrestricted cell division that could lead to harmful conditions like cancer.Jun 14, 2023 · Biology 2022 AP® Scoring Guidelines Question 4: Conceptual Analysis 4 points Existing isolated brook trout populations in Newfoundland, Canada, were once part of a larger population that was fragmented at the end of the most recent glaciation period about 10,000 to 12,000 years ago.4.2 Introduction to Signal Transduction. 4 min read • december 28, 2022.
