Document Summary

Protein synthesis: dna replication, transcription- makes mrna (nucleus, translation- goes into codons. 3d structure of enzymes and signaling molecules are important. Some enzymes break down molecules, but other enzymes build molecules. Each enzymes has its optimum environment (temp and ph). Allozyme-form of enzyme differ in amino acid sequence from other forms of same enzyme and is encoded by one allele at a single locus. Gene- a portion of sna that codes for the production of a protein (many of these proteins are enzymes) More precisely, a gene is a location on a chromosome. (where you except to find a certain kind of information. )an allele refers to the specific base sequence of that location. Decode: 3" gga ctt ctt ttt 5".

Ultimate- original cause- driven to increase fitness- why the behavior is favored- why it evolved.
