What is the main cause of succession whether it is primary or secondary succession

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs

Transcription factor binding would be reduced or eliminated, and transcription of the gene would decrease dramatically.

Explanation:

Mutation means the changing of the structure of the gene that results in the variant form which may be transmitted to the subsequent generations.  They are caused by the altering the the single base units in the DNA of the species.

In both eukaryotic as well as prokaryotic, the mutation can affect the diversity in the future generation of the cells.

The eukaryotic mutation of the gene affects the transcription of the gene as the transcription factor binding will be lowered or will be eliminated and the transcription of this gene will decrease.
