Place the correct word in the missing position to complete the sentences View Available Hint(s) Reset Help 1. An overabundance controls the expression of functionally related genes and consists of a control Repressor decreases expression of the structural genes This typically occurs in response to an repression of a substrate 3. If the repressor is bound to the operator, then RNA polymerase will not transcribe the structural genes 4 The control region controls whether RNA polymerase can advance along the DNA strand or not 5. The | promoter is the region of DNA where RNA polymerase initialiy binds r is not bound to the operator then RNAExplanation / Answer
Answers are given as follows:
1. Operon- Operon is the right answer here
The right answer to this blank is not overabundance. Overabundance is a term used in terms of substrate and when that occurs the expression of structural genes is decreased.
2. Respression and Overabundance- These are the right answers to the two blanks here.
As explained above when overabundance of substrate is there repression occurs which causes reduced gene expression.
3. Will not- This blank has been filled correctly.
4. Operator- This is the right answer here.
This region is present between the operon's genes and the promoter and is responsible for determining if RNA polymerase can advance or not.
5. Promoter- This blank has been filled correctly.
This region has the function of initiating transcription by facilitating binding of polymerase.
6. Will- This blank has been filled correctly.
Repressor as the name suggests has function of repressing expression so that means that in case it is not bound then RNA polymerase will not have anything that prevents transcription and hence the structural genes will be transcribed by the polymerase.
