Which statement concerning activator and repressor proteins in eukaryotes is true? activators and repressors are equally common in eukaryotes. activators and repressors are only found in prokaryotes. repressors are more common than activators in eukaryotes. activators are more common than repressors in eukaryotes.

Activators are more common than repressors in eukaryotes.

Explanation: This happens due to the complexity in eukaryote cells when compared to prokaryotic cells. They need the genes to be expressed in different regions at the same time, and that's why they have to use more activators than repressors in their genetic expression.

Repressor proteins are more common in eukaryotes than activator proteins.

Explanation:

Gene expression control in eukaryotes is more complex than in prokaryotes. Eukaryotic gene is regulated by a combination of several repressor proteins that work together.

The number of regulatory protein involved is higher

The regulatory binding sites are farther than the transcription promoter sites

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
