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.

How does the sexual life cycle of the human species introduce genetic variations?
kari74 [83]

Answer:

In humans, genetic variations are caused because humans reproduce by a sexual life cycle which is termed as meiosis. In such a life cycle, the offspring receives half the chromosomes from the mother and half from the father. Crossing over and  random assortment of chromosomes are two phenomenons which occur during meiosis. Due to these two phenomenons, genetic variations are caused.

During crossing over, the exchange of DNA segments between the homologous chromosomes takes place which brings about the genetic variations.
