Biology-Genetic engineering

• What is the definition of genetic engineering?

  Genetic engineering is a set of technologies used to change the genetic makeup of cells.
• What does genetic engineering involve?


  It involves directly manipulating an organism's genes using biotechnology.
• What can genetic engineering introduce into an organism?

  It can introduce new traits not found in that organism naturally.
• How does genetic engineering compare to traditional breeding methods?

  It allows for more precise and rapid genetic changes compared to traditional breeding methods.
• What are the key techniques used in genetic engineering?

  1. Gene isolation: Identifying and extracting a specific gene of interest. 2. Gene cloning: Making multiple copies of the isolated gene. 3. Gene transfer: Inserting the cloned gene into the target organism. 4. Genome editing: Using tools like CRISPR to edit DNA sequences.
• What does gene cloning involve?

  Gene cloning involves making multiple copies of the isolated gene for insertion into another organism.
• What is gene isolation in genetic engineering?

  Gene isolation is identifying and extracting a specific gene of interest from an organism's DNA.
• What is gene transfer in genetic engineering?


  Gene transfer is inserting the cloned gene into the target organism, often using vectors like viruses or plasmids.
• What is genome editing?


  Genome editing is using tools like CRISPR to precisely edit an organism's DNA sequence.
• What are the applications of genetic engineering?

  1. Agriculture: Modifying crops for pest resistance and higher nutritional value. 2. Medicine: Producing human insulin and vaccines. 3. Environmental remediation: Using engineered microbes to clean up pollutants. 4. Biofuels: Modifying microbes for efficient biofuel production. 5. Research: Genetically engineering model organisms to study diseases.
• In which field is genetic engineering used to produce human insulin?

  It is used in the field of medicine.
• How does genetic engineering contribute to agriculture?

  It modifies crops to be more pest/disease resistant and drought tolerant.
• What role does genetic engineering play in environmental remediation?

  It uses engineered microbes to clean up oil spills or break down pollutants.
• What ethical concerns are associated with genetic engineering?

  Concerns include safety and unintended consequences, equity and access, moral status of modified organisms, and eugenics.
• What is the ethical concern related to the potential environmental impact of GMOs?

  The concern is about safety and unintended consequences.
• Which ethical concern involves the risk of ecological disruptions from GMOs?

  Safety and unintended consequences.
• What does the ethical concern of equity and access refer to in genetic engineering?

  It refers to the potential high costs of genetic technologies limiting access and raising fairness issues.
• What are the societal impacts of genetic engineering?

  Impacts include medical advancements, agricultural productivity, environmental solutions, ethical debates, economic implications, and public perception.
• How has genetic engineering impacted public perception?

  It has influenced how people view science and technology in everyday life.
