WebMar 26, 2024 · The flow of information from DNA to RNA to proteins is one of the fundamental principles of molecular biology. It is so important that it is sometimes called the “central dogma.” Through the processes of transcription and translation, information from genes is used to make proteins. Credit: U.S. National Library of Medicine WebIn eukaryotes, chromosomes are in the nucleus and are linear. In prokaryotes, the chromosome is in the nucleoid region, and it is circular. Additionally, small DNA molecules called plasmids can be present in the prokaryotic cell. They carry non- essential information and can be exchanged between cells of the same generation. raymond cogan

WebMar 5, 2024 · In eukaryotes, additional regulatory sequences called enhancers and the proteins that bind to the enhancers are needed to achieve high levels of transcription. Enhancers are DNA sequences that regulate the transcription of genes. Unlike prokaryotic regulatory sequences, enhancers don't need to be next to the gene they control. WebJul 10, 2024 · As you have learned in introductory biology, in eukaryotic cells, this process is carried out in the cytoplasm of the cell, by large RNA-protein machines called ribosomes.
