Document Summary

The genetic code was must have been established very early in the history of life. Since it is shared almost universally by most organisms. In some ciliates (such as paramecium) uaa and uag are not stop codons, instead they code for gluatamine. Plastids and mitochondria have their own dna which code for proteins. Retinoblastoma- disruption of rb protein (fails to serve as a cell cycle break) leads to cancer on retinas. Delivery of chemotherapy drugs via liposomes to targets area, will hopefully reduce problems associated with side effects. Transcription errors resulted in acquired mutations in the rna, which lead to error in protein formation. May be linked to genetic mutations from dna transcription. Dr. andre studies cell proliferation and regulatory mechanisms involved in the maintenance of genome stability and the development of the cancer cell.
