Prokaryotes vs. Eukaryotes
Replication of DNA in a prokaryote is different from a eukaryote. In a prokaryote they have a single origin where the replication process starts. Also eukaryotes synthesize the same time they are being transcribed, and ribosomes will be active on the single mRNA while it is being synthesized. All the replication of a prokaryote takes place in the cytoplasm and cell membrane. In a eukaryote there is multiple origins where DNA replication starts. In eukaryotes there are more proteins that are involved therefore it is a more complex replication than a prokaryote. Eukaryotes carry out their replication in the nucleus, mitochondria, and the chloroplast.
The transcription of a prokaryote occurs in the cytoplasm. When transcription takes place there is no RNA processing. In the eukaryotic cell transcription takes place in the nucleus, mitochondria and chloroplast. When transcription is taking place in the eukaryotic cell, there is RNA processing. Translation in a prokaryote also takes place in the cytoplasm and is coupled with the transcription. In eukaryotes it is different, translation takes place in the mitochondria and chloroplast but is not coupled with the transcription.
In Prokaryotes, the gene regulation is determined with the position of the repressor. To make proteins, the RNA polymerase should attach to the promoter of the DNA. if there is an active repressor, this repressor prevents the RNA polymerase from binding to the promoter. In prokaryotes, substances like lactose involve gene regulation, because they bind to the repressor and stop it’s function. When the repressor becomes inactive, RNA polymerase
