Document Summary

Topic 1 the chemical basis of life. Proteins are the active workers in the cell information stored in dna is the genotype, and when the information is expressed as rna and protein, a phenotype is produced. Proteins are macromolecules, many of which are enzymes. All proteins are synthesized from combinations of 20 amino acids. Topic 2 amino acids and the peptide bond. 4 major classes of biomolecules: proteins, nucleic acids, carbohydrates, lipids. Dogma represents the flow of information where dna can become proteins. Dna can be replicated to form identical copies of itself. Transcription: copy of one dna strand is made, called rna: nucleotides in rna induces synthesis of protein; this is translation. Proteins have many different roles, including: structural proteins, enzymes, motor proteins. Proteins are composed of amino acids based on the genetic code. The rna strand has series of triple-bases called codons; these translate into a different amino acid on the polypeptide chain.
