Artificial Selection Noun

---

[ar-tuh-fish-uhl suh-lek-shn]

Back

Artificial Selection

---

The process where humans intentionally breed plants or animals to select for specific, desirable traits in the offspring.

---

Example: Humans select specific plant traits by choosing which flowers to breed, resulting in desired offspring.

Selective Breeding Noun

---

[suh-lek-tiv bree-ding]

Back

Selective Breeding

---

A method of artificial selection where humans breed organisms with specific desired traits to produce offspring with those same traits.

---

Example: Cross-pollinating flowers to produce offspring with desired traits shows selective breeding.

Natural Selection Noun

---

[nach-er-uhl suh-lek-shn]

Back

Natural Selection

---

The process where organisms with traits better suited to their environment are more likely to survive and reproduce successfully.

---

Example: Different finch beaks evolved to eat specific foods, showing natural selection.

Genetic Engineering Noun

---

[juh-net-ik en-juh-neer-ing]

Back

Genetic Engineering

---

The use of biological and chemical methods to directly change the arrangement of DNA that makes up an organism's genes.

---

Example: This diagram shows how DNA is organized into genes and chromosomes within a cell, explaining genetic engineering.

Front

Genes Noun

---

[jeens]

Back

Genes

---

Sections of DNA located on a chromosome that carry instructions for an organism's specific traits and direct cell activities.

---

Example: The image shows how genes are sections of DNA on a chromosome inside a cell, explaining their role in carrying instructions for traits.

DNA Noun

---

[dee-en-ay]

Back

DNA

---

The molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms.

---

Example: The image shows DNA's double helix structure with labeled base pairs and backbone, explaining genetic instructions.

Front

Chromosomes Noun

---

[kroh-muh-sohmz]

Back

Chromosomes

---

Thread-like structures made of DNA found in the nucleus of a cell that carry genetic information in the form of genes.

---

Example: Chromosomes are thread-like structures in the nucleus that carry genes made of DNA.

Front

Recombinant DNA Noun

---

[ree-kom-buh-nuhnt dee-en-ay]

Back

Recombinant DNA

---

A DNA molecule that has been artificially created by combining genetic material from different organisms into a single molecule.

---

Example: The image shows how DNA from different sources is combined to form recombinant DNA, which is then introduced into bacteria.

Genetically Modified Organism (GMO) Noun

---

[juh-net-ik-lee mod-uh-fahyd or-guh-niz-uhm]

Back

Genetically Modified Organism (GMO)

---

An organism whose genetic material has been altered using genetic engineering techniques to produce a desired characteristic.

---

Example: Scientists modifying DNA in a lab to create a genetically modified organism.
