LECTURE NOTES: SCIENCE, TECHNOLOGY & SOCIETY (FINALS REVIEWER 2024 Read and ANALYZE each statement/question carefully. Multiple Choice: Choose and shade the box/letter of the BEST answer. 1. Genetic Disorders: a disease that is caused by an abnormality in an individual’s DNA. 2. Vector: an organism that does not cause disease itself, but which carry the DNA from one host to another. An insect or animal that carries a disease from one animal or plant to another: 3. Plasmid: a genetic structure in a cell that can replicate independently of the chromosomes, typically a small circular DNA strand in the cytoplasm of a bacterium or protozoan. 4. Cloning: cloning describes a number of different processes that can be used to produce genetically identical copies of a biological entity. Cloning: the process of generating a genetically identical copy of a cell or an organism. 5. Germline Gene Therapy: therapy that involves modification of the genes inside germ cells (sperm or ova). During reproduction, these gametes fuse to form a zygote, which would divide and pass on the modified gene into all other cells of the body during the development of offspring. 6. Somatic Gene Therapy: therapy that involves insertion of therapeutic DNA into body cells and not germ cells or gametes. This means any effects of the therapy are confined to the individual being treated and are not inherited by future offspring. 7. Vector: an organism that does not cause disease itself, but which carry the DNA from one host to another. 8.

How Nanotechnology impacts human lives: Faster, smaller, and more powerful computers that consume far less power, with longer-lasting batteries; Faster, more functional, and more accurate medical diagnostic equipment. (lab- on-a-chip technology); Nanoparticles in pharmaceutical products improve their absorption within the body and make them easier to deliver, through combination of medical devices. Nanoparticles can also be used to deliver chemotherapy drugs to specific cells, such as cancer cells; Many drink bottles are made from plastic containing nanoclays, which increase resistance to permeation by oxygen, carbon dioxide, and moisture. This help retain carbonation and pressure and increases shelf life by several months; On the medical front, nanosensors can also be used accurately to identify particular cells or substances in the body. 71. Harnessing the immune response: strengthening the body’s existing ability to target and kill CA cells ( patient’s immune cells can improve their ability to find or kill certain forms of CA) 72. Gene therapy to enhance CA treatment: insert genes into CA cells that can make the CA cells more vulnerable to radiotherapy or chemotherapy, therefore, improving effectiveness of these treatments. 73. Blocking the protection of the CA cells: certain CA cells use to survive but can be blocked using gene therapy. For example, a process called apoptosis – refers to the programmed cell death of CA cells if it contains DNA that is damaged and beyond repair – ensure that the CA cells do in fact die rather than survive. 74. Pro-drug gene therapy: insertion of genes into CA cells that allow conversion of an inactive drug called a pro-drug into active form. The pro-drug does not harm normal cells and only reaches CA cells, where it is activated by the gene to become destructive. 75. Genetically Modified Organism (GMO): A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques. Genetic modification involves the mutation, insertion, or deletion of genes. 76.

Renewable Energy: energy supply that are replenished through natural processes. Renewable resources can be replenished over fairly short spans of time, such as months, years, or decades. 79. Alternative Energy Sources: are the answer to energy crisis. These are the ones which do not cause any undesirable consequences to people and the environment because they are renewable and are free. In the Philippines, renewable energy resources include solar, wind, geothermal, hydropower and biomass. 80. Hydroelectric Energy: potential energy stored in water held in dams made to drive a water turbine and generator which in turn produces electric power called hydroelectric power. 81.

Wind energy is an effective alternative source of energy in areas where the velocity of wind flow is high. 83. Geothermal Energy: new alternative energy source harnessed from deep underground chamber with high temperature originating from the earth’s core. Steams produced from these chambers cause turbine to move and later generate energy. 84. Biomass: is energy generated or produced by living or once-living organisms. The most common biomass materials used for energy are plants, such as corn and soy, above. 85. Nuclear Energy: rely on nuclear fusion they bombard or split uranium-235 to lighter elements called plutonium = emit neutrons and produce a tremendous amount of energy. However, the waste products are radioactive and harmful to living creatures. 86.
