This is a knitted model of DNA, complete with GC/TA base pairs represented by orange-green bars with a pointed join and blue-yellow bars with a stepped join (because there weren’t enough stitches to make a wave or curve), replicating the standard simplified DNA model. As you can see from the picture, it also makes a good toy insofar as it holds its shape while squished or stretched, because it is stuffed firmly with cotton balls. It was made with two equal black twisted tubes on size US 3 double-pointed needles (see the double-pointed needle tutorial and/or the tutorial on twisted…

THE BIOTECH GAME OF LIFE
In “The Biotech Game of Life,” which is similar to the Game of Life, each player is a scientist attempting to successfully bring his or her biotechnology product to the market. During the game, players will face many obstacles before obtaining a successful product and the first one to accomplish this wins. Below are the instructions, which provides more details on the game, and links to the game board and play money (pdf files). Note, that like the real thing, it is quite challenging to finish the game. – – – Gameboard (312K) $10,000 bills (916K) | $100,000 bills (767K)…
THE MACGYVER PROJECT: GENOMIC DNA EXTRACTION AND GEL ELECTROPHORESIS EXPERIMENTS USING EVERYDAY MATERIALS
Abstract: DNA extraction and separation by agarose gel electrophoresis is a simple and exciting process that anyone can perform. However, the high cost of specialized equipment and chemicals often hinder such an experiment from being carried by members of the high school community. Here, we describe a cost effective way of extracting and electrophoresing DNA under a prescribed MacGyver limitation – that is using only materials available from a grocery store or shopping mall. * * * In order to carry out this project, we decided to first divide the procedure into three specific sections, each to be addressed individually.…
