Answer:
C. Can't be observed directly
Answer:
transcription factors bind to the promoter, and RNA polymerase is then recruited to begin transcribing the gene
Explanation:
The transcription process in eukaryotes happens in 3 stages:
- Initiation
- Elongation
- Termination
The initiation of transcription starts when a set of proteins called the transcription binds to the promoter region of a gene on the coding strand of DNA. Thereafter, the RNA polymerase enzyme binds to the promoter region thereby opening up the double helix structure of the DNA in anticipation of transcription.
During elongation, RNA nucleotides are added to the growing RNA strand in 5' to 3' direction with the DNA unwinding and winding back as the polymerase moves along the coding strand in 3' to 5' direction.
Transcription terminates when the RNA polymerase gets to the end of the gene being transcribed signalled by a sequence of DNA known as the terminator.
<em>Hence, in the illustration, the correct answer would be that the transcription factors bind to the promoter, and RNA polymerase is then recruited to begin transcribing the gene.</em>
Answer:
The correct answer would be Bacteria toxin.
High temperature or fever is one of the symptoms associated with bacterial or viral infection.
Our immune system increases the temperature of our body in response to antigen or toxin associated with infectious agents such as bacteria or virus.
It makes the body or environment less favorable for bacteria or other infectious agents as they are temperature sensitive.
