A-T(Adenine-Thymine)‚ G-C(Guanine-Cytosine) A-U(Adenine-Uracil)‚ G-C(Guanine-Cytosine) Stability: Deoxyribose sugar in DNA is less reactive because of C-H bonds. Stable in alkaline conditions. DNA has smaller grooves‚ which makes it harder for enzymes to "attack" DNA. Ribose sugar is more reactive because of C-OH (hydroxyl) bonds. Not stable in alkaline conditions. RNA has larger grooves‚ which makes it easier to be attacked by enzymes. Propagation: DNA is self-replicating. RNA is synthesized from DNA when

In the Penny Cleaning Lab‚ my hypothesis‚ which stated that the lemon juice would be the best at cleaning the penny since it is an acid and acids are particularly good at cleaning metallic substances‚ was indeed valid. First‚ we started out with 1mL solutions of all the substances in the test tray. We dipped the pH paper in each solution for about a second and recorded the pH level for each substance. Before starting‚ we noticed that all the pennies were in some shade of brown‚ which I predicted

The drinking water has an alkaline pH between 7.0 and 9.5‚ which means that the water contains a healthy level of alkaline minerals such as calcium and magnesium. Micro-clustered. Water that is electrolyzed or "reduced" will have smaller groupings of water molecules. Drinking reduced water can improve cellular

water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will change because the hydrogen ions of contained within will balance between the soil and water. PH is a measurement system representing how acidic or alkaline something is. It is represented by a 1-14 scale‚ with

pH Levels and Temperature Water is very important in life. Without water‚ nothing could survive. Water needs to be clean to drink. People all over the world are using filters to clean and purify water. The best type of filter‚ out of dirt‚ cloth‚ and grass‚ is the grass filter (Allen). The grass filter is completely natural‚ therefore it cleans and purifies the water the best. Does a grass filter affect the pH level and temperature of lake and stream water? The temperature of water affects how solubility

Although sugar is the primary nutrient used‚ when a microbe runs out of it‚ protein or other nutrients will be attacked. This causes changes in the color of the medium because of the pH indicator added to detect acid production. When proteins are used‚ alkaline by-products are produced and the medium can change colors. If you let these sugar tests go for more than a day‚ you risk the possibility that the color will have changed and you may misread the test result. C. What is the purpose of adding phenol

Immunohistochemistry or IHC refers to the process of detecting antigens (e.g.‚ proteins) in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues.[1] IHC takes its name from the roots "immuno‚" in reference to antibodies used in the procedure‚ and "histo‚" meaning tissue (compare to immunocytochemistry). Immunohistochemical staining is widely used in the diagnosis of abnormal cells such as those found in cancerous tumors. A video
