DNA Extraction

To request field trip dates, visit https://oepreg.bnl.gov/.
Students learn DNA is the genetic material in living organisms that determines traits. Using processes such as precipitation and spooling, students extract DNA from cells to understand the differences between prokaryotic and eukaryotic cells.
Vocabulary: DNA, extraction, genes, lipids, precipitate
Session Information: This activity is available in-person only.

1.1a Living things are composed of cells. Cells provide structure and carry on major functions to sustain life. Cells are usually microscopic in size. 1.1c Most cells have cell membranes, genetic material, and cytoplasm. Some cells have a cell wall and/or chloroplasts. Many cells have a nucleus. 2.1a Hereditary information in contained in genes. Genes are composed of DNA that makes up the chromosomes of cells. 2.1b Each gene carries a single unit of information. A single inherited trait of an individual can be determined by one pair or by many pairs of genes. A human cell contains thousands of different genes. 2.1c Each human cell contains a copy of all the genes needed to produce a human being. 2.1e In sexual reproduction typically half of the genes come from each parent. Sexually produced offspring are not identical to either parent. 2.2a In all organisms, genetic traits are passed down from generation to generation. |
