Alternatives to Adderall? Hello. I've been taking Adderall XR 15mg for the last few months, upped from 5 mg twice a day. It's made an amazing improvement in my work life...focused, less mistakes, on the ball. Here it is...a short time later the effects of it aren't working like they used too. I can hardly focus on this screen as I type currently.
DNA is a complex molecule that is found in all living organisms. Constructing DNA models is a great way to learn about DNA structure, function and replication. DNA contains the genetic information for the reproduction of life. nucleotide is composed of a phosphate, a deoxyribose sugar molecule, and a nitrogen-containing base (A, T, C, or G). The instructions carried on DNA are used to make proteins from amino acids in the cytoplasm.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.Similar to the way the order of letters in the alphabet can be used to form a word, the order of nitrogen bases in a DNA sequence forms genes, which in the language of the cell, tells cells how to make proteins.ach nucleotide contains a phosphate group, a sugar group and a nitrogen base.
