Answer 1

Question 8)

The right option are:

*Use of repressor protein to limit binding of RNA polymerase.

*Regulating the availability of transcription factor.

Both of these factors are found in eukaryote as well as prokaryotes.

Other option are wrong :

* histone protein are found in eukaryote only and they are not found in prokaryotes.

*Alternative splicing is found in eukaryote and it is not found in prokaryotes

*Capping and tailing in mRNA is found in eukaryote and it is not found in prokaryotes.
