Answer:
In E. coli promoter there are two consensus sequence which is located upstream to from the start site of the transcription. One consensus sequence is present at -10 and one at -35.
These consensus sequences are necessary to be recognized to start the transcription. It is recognized by the sigma factor which is a part of RNA polymerase. After recognition transcription starts.
The termination of transcription occurs by a rho protein. Rho is ATP dependent RNA stimulated helicase which disrupts the complex of RNA-DNA and terminates transcription.
The answer is; C
Radioactive waste is dangerous because it continues to decay releasing radioactive elements and harmful electromagnetic radiation that can destroy genetic material – hence cause cancer. The waste, therefore, has to be stored safety, and avoiding any contamination to the environment, and also for long periods of time until there is enough time for decay into less harmful products.
