Describe the interactions between RNA polymerase and promoter sites that lead to the initiation of transcription. Predict what would happen if the promoter sites were damaged.

In order for RNA polymerase to complete transcription and create mRNA the promoter is needed. The promoter is what tells RNA polymerase where to start transcription. If the promoter is damaged in any way, transcription most likely will not occur.

Eukaryotic cells are theorized to have evolved from prokaryotes called the endosymbiotic theory. this explains that the most primitive eukaryotic cell engulfed a prokaryotic cell (by the process of phagocytosis) that is capable of cellular respiration and another prokaryotic cell that is capable of photosynthesis. these prokaryotic cells eventually became organelles and these organelles are the mitochondria and the chloroplast
