Answer:
the correct answer is - a slight difference in factors and their mechanism of transcription such as Nucleotides, polymerase enzyme, and promotor regions.
Explanation:
All types of organism species have exact same nucleotides in their mRNA and DNA. Transcription is also initiated with the similar type of the promotor region in all species.
Slightly differences in any of these or mechanisms can be useful and help to create an evolutionary phylogenic tree or cladogram in various species. The polymerase enzyme is also similar in the various species.
Thus, the correct answer is - a slight difference in factors and their mechanism of transcription such as Nucleotides, polymerase enzyme, and promotor regions.
The answer is fitness. Fitness means it’s ability to survive and replicate.
