Have you picked up any new hobbies during the pandemic? Like many others, I have expanded my baking, which used to be limited to a weekly challah (for our Friday night Shabbat dinner). In the past few months I’ve made rye bread, sour dough, French bread, French apple cake, ice cream pie, banana bread, Torte Caprese (flourless chocolate cake), amaretti cookies, and a few tres leches cakes. My poor kids grew up with a mom that never baked, and now that we’re empty nesters, I’m baking up a storm!
I’ve also put two bird feeders outside, and now have a new part-time job refilling them EVERY SINGLE DAY!
How about you?
See ya on the Net,

DNA (deoxyribonucleic acid) is a long, spiraling molecule that carries the genetic codes that enable cells to reproduce. Although DNA was first isolated by Friedrich Miescher in 1869, it’s double helix structure wasn’t discovered until 1953 by James Watson and Francis Crick. For their groundbreaking work, Watson and Crick shared the 1962 Nobel Prize in Physiology/Medicine with Maurice Wilkins.
DNA “is special, because it holds the code for every cell in your body. That’s right. Every cell in your body uses DNA as an instruction manual. If you want to take away the importance of that statement, you can say that DNA is just a long spiral chain of nucleotides. But it’s more. So much more.” Continue your biochemistry lesson by following the Next Stop button at the bottom of the article.
DNA from the Beginning
DNA from the Beginning is “an animated primer of 75 experiments that made modern genetics,” published by the Cold Spring Harbor Laboratory, a not-for-profit research and education institution. Each primer includes a description, an animated slideshow, a related video and links to related sites. The first one explores Gregor Mandel’s groundbreaking work in how various human traits are passed from generation to generation.
Learn.Genetics: DNA Basics
Learn.Genetics is a genetics education outreach program from the University of Utah. In addition to their jargon-free resources for students, they have printable classroom guides for teachers. Don’t miss the interactive Build a DNA Molecule activity, the DNA Extraction Virtual Lab, and my personal favorite: How to Extract DNA From Anything Living. Using a blender, detergent, meat tenderizer, alcohol and a source of DNA such as peas or chicken livers, you can isolate long, stringy DNA molecules in a test tube. Look for step-by-step instructions in the Virtual Labs section.
