Document Summary

Biochemistry 2288a / 2280 a final exam (topics 22 28) 3 major topics: gene expression, recombinant dna technology, molecular basis of cancer. Info stored in dna in the form of genes. In any one cell type ~10,000 are expressed at various levels. Not all genes are expressed at the same level. In order to code for life, the information within dna must be expressed. The expression of the correct genes is essential for growth and differentiation of all cells. Right ones are one and others are off. Out of the blue print of life, expression of genes is how we define life. Most disease states, most notably cancer, result from or are manifested by alternations in expression of one or more genes. By manipulating gene expression profiles, we have the potential to prevent or reverse disease states. Why is there an rna step in gene expression: the rna step allows genes to be expressed at different levels.
