WebIn eukaryotes like humans, the main RNA polymerase in your cells does not attach directly to promoters like bacterial RNA polymerase. Instead, helper proteins called basal ( general) transcription factors bind to the promoter first, helping the RNA polymerase in your cells get a foothold on the DNA. WebThe genome of eukaryotes consists of 10,000–50,000 genes carried on several chromosomes. Eukaryotic chromosomes are linear, unlike the circular chromosomes of bacteria. Most eukaryotes are diploid, with two copies of each chromosome. Consequently, they possess at least two copies of each gene.

WebA mutation that inactivates the regulatory gene of a repressible operon in an E. coli cell would result in 1. irreversible binding of the repressor to the operator. 2. continuous transcription of the structural gene controlled by that regulator. 3. inactivation of RNA polymerase by alteration of its active site. hindi ako laruan imelda papin

Web37 minutes ago · This is further supported the absence of lytic effects of P[5]a on eukaryotic lipid bilayer membranes, which are also composed of glycerophospholipids (Fig. 5a–e, supplementary Fig. 11). WebMost of the E. coli enzymes have counterparts in eukaryotic DNA replication, but a single enzyme in E. coli may be represented by multiple enzymes in eukaryotes. For instance, there are five human DNA polymerases with important roles in replication ^5 5 . Most … WebInterestingly, eukaryotic transcription can be influenced by the binding of proteins to regions of DNA, called enhancer s, rather far away from the gene, through DNA looping facilitated between the enhancer and the promoter ( Figure 11.40 ). hindi akbar birbal stories
