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.
Part of the information on the long DNA molecules consists of signals or signposts to show where a strand of RNA should start and stop. So the DNA sequence contains two different types of information: the three-base codons that tell the RNA how to put amino acids together in a protein, and separate control signals that show where an RNA molecule should start and stop.
