WebDNA replication will be initiated immediately to the left of the RNA, since DNA polymerase requires an RNA primer. Molecular biologists are studying the processes of transcription and translation and have found that they are very similar in prokaryotes and eukaryotes, as summarized in Table 1. WebProkaryotic cells typically have a single, circular chromosome located in the nucleoid. Since prokaryotic cells typically have only a single, circular chromosome, they can replicate faster than eukaryotic cells. In fact, a …
