Document Summary

Theme 3 module 4: turning off the signal. Gene expression can be regulated at many different points during the synthesis of a functional protein such as: transcription initiation, rna processing, the overall stability of the rna molecule, protein synthesis, protein modifications and transport, protein degradation. Multi-level regulation enables a cell to rapidly alter the levels of active proteins in response to internal and external signals. Gene found during development in the intact. Complementary probe to the mrna of interest would be a fluorescently labelled short single-stranded segment of dna or rna, and will bind to the target mrna in a complementary fashion. In situ hybridization can be used to study the expression of one or a few genes of interest. Can be carried out and compared throughout the different stages of development to attain a better understanding of temporal differences. In situ hybridization is useful to assess the gene expression levels of a few genes of interest.
