Study Notes
Unnatural Selection
- Scientists are changing genetic traits in plants and animals.
- CRISPR is a simple, new gene-editing method.
- CRISPR could be used on humans.
- Evolution is the process of changes in plants and animals over time.
- "Steer" controls the direction of something, like evolution being affected by survival needs.
- "Upend" is to turn something over, in this case, turning traditional biological processes on their heads.
- "Alter" means to change something, such as altering different species.
- "Species" are groups of similar organisms that can produce offspring.
- "Transgenic" organisms have genetic material from unrelated organisms.
- "Fluorescent" describes something that glows brightly.
- "Jellyfish" are a type of animal that glows.
- CRISPR is a new gene editing tool.
- It's faster, cheaper and more accurate to previous techniques.
- CRISPR has many possible useful uses.
- "Game changer" refers to something that causes a significant change in how things are done.
- A scalpel is small, sharp knife (sometimes detachable blade) used for surgery.
- A cleaver is a thick knife used for chopping meat.
- A gene is a part of a cell that influences an organism's traits.
- A trait is an inherited characteristic.
Gene Editing Procedure & Applications
- PGD (Pre-implantation Genetic Diagnosis) identifies specific genes in embryos.
- Diseases and traits like eye color can be identified.
- Embryos are in early stages of development.
- Drooping is a slumping position or behavior.
- "Formulate" means to create something with careful thought.
- A "fruit fly" is attracted to rotting fruit.
- A "bristle" is a stiff hair.
- "Biopsy" is a tissue sample taken from a living organism.
- A "chromosome" contains genes that control how an organism grows.
- "Fertilize" an egg means to make it able to grow.
- Sperm is the cell that fertilizes the egg.
- "Yolk" is the food source for an embryo.
