Learn Biology Online For Free with our Huge Collection of Open Courses If you’ve always been interested to learn more about nature and the diversity of life, you can now Learn Biology Online for Free! Free Biology courses are easy to find yet some of the ones you find may not be worth your time. We’ve put together a list of Biology courses from well-respected institutions such as John Hopkins, Yale, MIT, Stanford, and UCLA. Cell Structure All living organisms on Earth are divided into cells. The main concept of cell theory is that cells are the basic structural unit for all organisms. Cells are small compartments that hold the biological equipment necessary to keep an organism alive and successful. Living things may be single-celled or they may be very complex such as a human being.

Cystic Fibrosis - Gene Mutations and CFTR protein Located on human chromosome 7, the CFTR gene is made up of 250,000 DNA nucleotides. CFTR stands for Cystic Fibrosis Transmembrane Conductance Regulator. The CFTR protein functions as a channel for the movement of chloride ions in and out of cells, which is important for the salt and water balance on epithelial surfaces, such as in the lungs or pancreas. Changes in the CFTR gene can affect the structure of the CFTR protein. As in every human gene, the DNA sequence is transcribed into a messenger molecule called mRNA. The CFTR gene has 27 segments called exons that are spliced together to make the complete mRNA message.

10 Best Tools for Teachers and Students to Use in 2014 All teachers have a goal to establish clear, friendly, but authoritative communication with students and their parents. Parent meetings are not the most relaxed environment for the teachers to share their expectations and plans, which is why many educators have started using online tools to make this process easier. As a teacher, I have been using many web-based tools to bring some fun into the classes and make the communication with my students and their parents more effective. I’ve chosen some of the most useful tools to present in this list, which will hopefully be implemented in the teaching techniques of an increased number of educators during the upcoming year. 1. WoodGas Stove WoodGas Stove A few ideas about a stove developed by Ray Garlington Late September 2003, Ray developed a page on a new "batch-loaded, inverted down-draft gassifier" stove.

Diversity "Diversity is not about how we differ. Diversity is about embracing one another's uniqueness." - Ola Joseph "United we stand, divided we fall." - Aesop (620 -560 B.C.) Cells early 12c., "small monastery, subordinate monastery" (from Medieval Latin in this sense), later "small room for a monk or a nun in a monastic establishment; a hermit's dwelling" (c.1300), from Latin cella "small room, store room, hut," related to Latin celare "to hide, conceal." The Latin word represents PIE root *kel- "conceal" (cf. Sanskrit cala "hut, house, hall;" Greek kalia "hut, nest," kalyptein "to cover," koleon "sheath," kelyphos "shell, husk;" Latin clam "secret;" Old Irish cuile "cellar," celim "hide," Middle Irish cul "defense, shelter;" Gothic hulistr "covering," Old English heolstor "lurking-hole, cave, covering," Gothic huljan "cover over," hulundi "hole," hilms "helmet," halja "hell," Old English hol "cave," holu "husk, pod").

Protein Data Bank - RCSB PDB A Structural View of Biology This resource is powered by the Protein Data Bank archive-information about the 3D shapes of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease. As a member of the wwPDB, the RCSB PDB curates and annotates PDB data. The RCSB PDB builds upon the data by creating tools and resources for research and education in molecular biology, structural biology, computational biology, and beyond. Use this website to access curated and integrated biological macromolecular information in the context of function, biological processes, evolution, pathways, and disease states. 700 Free Online Courses from Top Universities Get 1200 free online courses from the world’s leading universities — Stanford, Yale, MIT, Harvard, Berkeley, Oxford and more.
