Similarities Between Prokaryotic And Eukaryotic Cells

Cells were divided into two, which are, prokaryotic and eukaryotic cells. Examples of prokaryotic cells are Bacteria and Archae, while the examples of eukaryotic cells are Protists, Fungi, plants and animals. All cells share certain basic features, but the major difference between prokaryotic and eukaryotic cells is their DNA. Thus, these two cells have different features on DNA transcription and protein synthesis mechanisms. The general processes of transcription may be applied to both prokaryotic and eukaryotic cells as their basic biochemistry was the same. But, they are differs in their specific mechanisms and regulation of transcriptions. In all species, the process of transcriptions begins with the binding of RNA polymerase complex to a special DNA sequence at the beginning of the gene, which named promoter. The activation of RNA polymerase leads to initiation of transcription and followed by elongation of transcription. And these two cells were different in these elements.…show more content…
In contrast, eukaryotic cells are more complex than prokaryotes as their transcriptions process are utilize by three different types of RNA polymerase. These polymerases differ in number and type of subunits they contain and also the class of RNA they subscribe. RNA polymerase I, which located in the nucleolus, transcribe ribosomal RNA (rRNA), RNA polymerase II, which located in the nucleoplasm, transcribe messenger RNA (mRNA) and RNA polymerase III, which also located in the nucleoplasm, transcribe both ribosomal and transfer RNA (tRNA). All eukaryotic RNA polymerases are homologous to one another and to prokaryotic RNA
