Fraction Steps vs BioCaL

Fraction Steps app is a great way to learn and practice fractions visually and intuitively. Whether you're a student or just looking to brush up on your math skills, our fractions app is the perfect tool for you! It is so much fun and visual. In the app, we cover the following lessons: - Introduction -- Halves and quarters -- What is a fraction? -- Fraction on a number line - GCD and LCM -- Greatest common divisor -- Least common multiple - Equivalence -- Equivalent fractions -- Equivalent fractions on a number line -- Simplifying fractions - Comparison -- Comparing like fractions -- Comparing unlike fractions - Addition -- Adding like fractions -- Adding unlike fractions - Subtraction -- Subtracting like fractions -- Subtracting unlike fractions - Types -- Proper and improper fractions -- Mixed fractions -- Mixed to improper -- Improper to mixed - Multiplication -- Multiplying fractions -- Multiplying fractions intuition - Division -- Dividing fractions

Experimental research in molecular biology requires fundamental techniques such as restriction enzyme digestion and DNA ligation, which are essential for recombinant DNA technology and widely practiced in laboratories worldwide. Mastering these techniques is crucial for progress in biological research. Our app simplifies these processes by providing precise volumes for each component required in restriction digestion and ligation reactions. Users no longer need to calculate DNA volumes manually; instead, they input the desired DNA concentration, and the app calculates the necessary volumes for your reactions. The app then conveniently provides these volumes, so you can quickly set up your reactions ready for incubation at the appropriate temperatures in Eppendorf tubes. Additionally, our app offers the necessary DNA volumes for DNA assembly reactions, accommodating up to six different DNA fragment assemblies when constructing and using two or more DNA molecules. This user-friendly app ensures seamless operation, allowing instant use without the need for detailed instructions. It also guides users in sampling volumes to normalize mass and molar concentration across tubes with containing different DNA concentrations and sizes. Furthermore, it provides options for calculating various physical quantities of DNA and RNA of interest. Please note that all calculations involving DNA experiments are performed on double-stranded DNA molecules in BioCaL. The app also includes features for normalizing cell optical density to adjust the number of cells taken from different samples, as well as evaluating plasmid DNA copy number per cell and cosmid packaging efficiency, facilitating thorough analysis and efficient experiments.
