soldier1979 [14.2K]

Out of the following given choices;

contain ribose

consist of two strands

made of nucleotides

have an R group

The answer is 'made of nucleotides'. This is because out of the choices, DNA and RNA share the similarity of being made of nucleotides. However, while DNA is made of deoxyribose nucleotides, RNA is composed of ribose nucleotides. This difference is that in deoxyribose nucleotide, the 2nd carbon has a hydroxyl group while ribose nucleotide has hydrogen.

A transcriptional repressor that controls the transcription of gene A is not normally active unless bound by an effector molecul
iren [92.7K]

Answer:

Increase in transcription

Explanation:

Transcription is the process of forming RNA from DNA. It can be controlled by many factors like a repressor. Repressor can bind to the operator region of the promoter and hinder the movement of RNA Polymerase enzyme, halting the process.

Here, it is given that the repressor needs to first bind to an effector molecule X. Once it binds to X, it is activated and then it can bind to operator of gene A to inhibit its transcription. If the X binding domain on repressor is mutated it wont be able to bind to X. Thus it wont get activated and wont be able to attach to operator region to inhibit transcription. Hence, transcription process will keep going on uncontrolled.
