[Solved] Genes are really just segments of DNA in patterns of As, Ts, Gs, and Cs. How does an RNA polymerase "know" where to start transcribing at the beginning of a particular gene? A) The polymerase finds the end of the previous gene and copies past that point. B) The polymerase starts transcribing anywhere because the beginning point counts only during translation. C) It looks for a specific promoter region that marks the beginning of a gene. D) RNA polymerase does not know, so it has to rely on the ribosome to help it start at the correct place. Scanning Electron Micrograph: An image produced using a scanning electron microscope to examine surfaces of materials at high magnification. Transmission Electron Micrograph: An image produced using a transmission electron microscope to explore the minute structures within cells and tissues. Light Micrograph: An image produced using a light microscope, allowing for the visualization of small structures not visible to the naked eye. Electron Microscope: A type of microscope that uses a beam of electrons to create an image of the specimen, allowing for much higher resolution than light microscopes.
