NGSS STANDARDS COVERED BY THIS DNA EXTRACTION LAB:
Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism. Emphasis is on conceptual understanding that changes in genetic material may result in making different proteins. Assessment does not include specific changes at the molecular level, mechanisms for protein synthesis, or specific types of mutations.
Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring. Assessment does not include the phases of meiosis or the biochemical mechanism of specific steps in the process.
