Document Summary
The potential function and importance of the gene/protein can be determined through identification, isolation and survival of mutants. An environment where the mutant can survive, since it displays the wild type phenotype. Under nonpermissive conditions (too cold) mutant phenotype is displayed and mutants can"t survive: define (or compare and contrast): a) gene expression; transcription; replication; translation; b) gene; allele a) transcription: an. Gene expression occurs when a gene is turned on, and forms a product such as a protein. Choose two model organisms and explain your reasoning. Model organisms can be easily studied and are used in place of species that can"t be study in the same manor. Stores information: coding for proteins and rna, and contains regulatory signals 2. Replicates faithfully (preservation of information): semi-conservative, complementary base pairing, preserves genes important to organism"s survival 3. Phosphodiester bonds hold the sugar to the phosphate backbone.
