Answer: The answer is Morphological Species Concept

Explanation:

Species concept includes defining the differences between two or more species, especially similar species.

Morphological Species Concept is also known as Typical Species Concept, it includes defining these differences in species using their morphological attributes such as difference in shapes of their bodies, form, structure, colors, what they look like in the inside.

The Morphological Species Concept takes into account the Anatomical features or structures and not the genetic makeup or DNA of the species.

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.
