The correct Answer is:
To answer the question "DNA is a negatively charged molecule, hence it moves towards the", we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Charge of DNA**: - DNA is a molecule that carries a negative charge due to its phosphate backbone. Each phosphate group in the DNA structure contributes a negative charge. 2. **Identifying the Electrode Types**: - In an electrophoresis setup, there are two types of electrodes: - **Anode**: This is the positively charged electrode. - **Cathode**: This is the negatively charged electrode. 3. **Understanding Movement Towards Electrodes**: - Charged particles move towards the electrode with the opposite charge. Since DNA is negatively charged, it will move towards the positively charged electrode. 4. **Conclusion**: - Therefore, since DNA is negatively charged, it will migrate towards the anode, which is the positively charged electrode. 5. **Final Answer**: - The correct answer is **Option 2: Anode**.

Given below are four statements pertaining to separation of DNA fragments using gel electrophoresis. Identify the incorrect statements. (a) DNA is negatively charged molecule and so it is loaded on gel towards the Anode terminal (b) DNA fragments travel along the surface of the gel whose concentration does not affect movement of DNA. (c) Smaller the size of DNA fragment larger is the distance it travels through it. (d) Pure DNA can be visualized directly by exposing UV radiation.

A cubical container having each sides as l is filled with a gas having N molecules in the container. Mass of each molecule is m . If we assume that at every instant half of the molecules are moving towards the positive x-axis and half of the molecules are moving towards the negative x-axis.Two walls of the container are perpendicular to the x-axis. Find the net force acting on the two walls given? Assume that all the molecules are moving with speed v_(0) .

Many organic substances are negatively charged e.g.,acetic acid, while others are positively charged e.g., ammonium ion. An amino acid under certain conditions would have both positive and negative charges simultaneously in the same molecule. Such a form of amino acid is called
