WebRecall Prokaryotic transcription: – Transcription factors bind to specific DNA sequences upstream of the start of operons, or sets of related genes. – Transcribed mRNA is directly translated by ribosomes. In Eukaryotes, – Each gene has its own transcriptional control (no operons) – mRNA is processed before translation Eukaryotic Genes ... WebFeb 21, 2024 · The genetic material of prokaryotic cells in a single chromosome is made up of a single strand of DNA. A critical protein, histone protein, that is found bound in the chromosomes of eukaryotes is absent in prokaryotic cells. Prokaryotic cells also lack the nucleolus and the mitotic apparatus. WebJul 31, 2024 · The genes are located on the chromosomes at a specific location called the locus. The genes and the DNA are compactly packed in the chromosome. Each nucleated cell contains the whole set of the genome. In humans, the genome is composed of 23 pairs of linear chromosomes packed with the help of histone proteins. cukani svalu
