Question 6: You are performing an enzymatic reaction to digest DNA and nothing works for you. You need to find out why. You added the enzyme and the DNA to the reaction yourself and you are sure you did it right. It must be the digestion buffer. The working solution for the digestion buffer should contain 400 mM Tris, pH 8.0 and 125 mM MgCl2. First, you ask your colleague how he made the digestion buffer and he says: "I mixed 0.2 ml of 2M Tris, pH 8.0 stock solution 0.25 ml of 5M MgCl2 stock solution and I completed the solution with 0.55 ml water to make a final volume of 1ml." a) Before checking your colleague's calculation, what important question do you have to ask first for this specific solution? (not a generic question about all solutions) b) You are satisfied with his answer to a) and you believe he made a dilution error. You use the equation that applies to dilutions to check his calculations. Aha! you find the problem. What is it and how did you find out? Note: you can either check the math of your colleague or do the calculations yourself.
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
I could use some help with my biology lab assignment. I attached a picture of the question. I'm not sure how to solve and would love an explanation!
Enzymes are proteins that catalyze chemical reactions in living organisms. They function by lowering the activation energy required for a chemical reaction to occur, thereby speeding up the reaction without being consumed in the process. Enzymes are highly specific in the reactions they catalyze and can be regulated in various ways, such as through the presence of inhibitors or activators, post-translational modifications, or changes in pH or temperature. Enzymes are essential for many biochemical processes in the body, such as digestion, energy production, and DNA replication.
