CK-12 Biology Workbook complements its CK-12 Biology book.
This pathway provides an overview of the four classes of biological molecules (lipids, carbohydrages, proteins and nucleotides) and how they are assembled.
Paul Andersen describes the major mutations found in the living world. He starts with an analogy comparing the information in DNA with the information in a recipe. Changes in the DNA can result in changes to the protein, like changes in the recipe can result in changes in the food. [7:02]
This pathway describes how DNA ligase, a key enzyme in DNA replication, is used in gene cloning to create a recombinant plasmid. This pathway supports ABE lab 3: Building a Recombinant Plasmid.
This pathway explains how restriction enzymes are used in gene cloning to obtain the DNA pieces that will create a recombinant plasmid. This pathway supports ABE labs 2, 2a, 3, 4, and 4a.
This video illustrates how to test guide RNAs to facilitate the cleaving of a macrophage gene in vitro.
Video lesson presents an introduction to what cancer is and how it is the by-product of broken DNA replication. [12:35]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
Meet a chemist who owns his own business that develops synthetic DNA molecules designed to reprogram cells and help cure diseases. Hear the importance of writing, communication skills and creativity to becoming a successful chemist.
Read the career profile of the genetic counselor, who spends time with patients advising them of their options when deciding about the risks of genetic disease. Science Buddies lays out the educational requirements as well as the job requirements of this important medical career.
Through a narrated presentation learn about the cell theory, and find out about the characteristics all cells share. [6:38]
In this interactive activity adapted from the University of Nebraska, learn how and where transcription and translation occur within a cell and observe both processes in detail.
This pathway explores the processes of transcription and translation that allow cells to produce proteins from DNA.
This video explains how to sort small molecules using a technique called column chromatography.
Paul Nurse describes his research that showed that humans share some genes with organisms as different from us as simple brewer's yeast. Footage from Secret of Life: "Immortal Thread."
Esta vía explica cómo se utilizan las enzimas de restricción en la clonación de genes para obtener las piezas de ADN que crearán un plásmido recombinante. Esta vía es compatible con los laboratorios ABE 2, 2a, 3, 4 y 4a.
In questo video didattico, gli insegnanti delle scuole superiori Anu Deshpande e Aaron Matthieu spiegano cos’è un plasmide e perché è uno strumento utile nella biotecnologia.
Questo video spiega come ordinare le molecole piccole utilizzando una tecnica chiamata cromatografia su colonna.
