Document Summary

Human genome encodes ~25000 different protein encoding genes. In any one cell type ~10 000 are expressed at various levels; different cells will express different genes as they will require different proteins for specified functions. The expression of the correct genes is essential for growth and differentiation of cells. The differences in the gene expression of cells is what differentiates them. Many diseases are due to altered expression of one or more genes. By manipulating gene expression, we have the potential to prevent or reverse disease. Dna is transcribed into the rna, which is then translated into protein. Steps at which gene expression can be regulated in a eukaryotic cell. To be functional, the mrna must be exported from the nucleus to the cytoplasm. Acetylation, methylation, phosphorylation, cleaving of protein etc. The modifications are essential for the protein to be active and functional. Again, depends of rate of synthesis and rate of decay of the protein.
