Answer:
D) presence of transcription activators or repressors
Explanation:
The reason why this is not post-transcriptional regulation is that activators actually start the process of transcription by binding to specific sites. while on contrary when repressor binds it halt the process.
For example, there is a protein called CAP which in the presence of cAMP bind with promoter region and enhances the activity of RNA polymerase . While in the absence of cAMP it can not bind to promoter hence the transcription stooped.
Answer:
this is system approach,
Explanation:
This is an old concept first proposed by Ludwig Von, for better understanding of complexity of a complex unit,.
This approach places individual elements in their environment, and study them through observation of the relationship they share with one another. It underlying principle in any organisation is that workers' well being is related to the product outputs.Thus an improvements in the system, has a postie effects on the outputs and and satisfaction of the workers.
