Document Summary

The amount of gene products from an organism depends on conditions and signals, so the gene expression is regulated so that the right products are present at the right time and in the right amount. Gene expression can be regulated at many different points during the synthesis of proteins transcription initiation, rna processing, the overall stability of the rna molecule, protein synthesis, protein modification/transport and protein degradation. Enables the cell to rapidly alter the levels of active proteins in response to internal and external signals. If we suspect that a specific gene plays an important role in the embryonic development of the fruit fly drosophilia; To identify which embryonic cells or tissues express a gene by looking at where the produced mrna is found during development in the intact organism (in situ) In situ hybridization: mrna is detected with a complementary probe (short single-stranded segment of.
