What protein structure are enzymes? What is the relationship between proteins and enzymes? What are the components and structure of a DNA nucleotide? What is the purpose of operons in protein synthesis? What is the structural feature that allows DNA to replicate? What are the main structural fe...
A predictive biophysical model of translational coupling to coordinate and control protein expression in bacterial operons. The biophysical model also accurately predicted the translation rates of the nine protein atp operon, compared to ribosome profiling measurements. Altogether, ... Tian,Howard,M,.....

DNA electrophoresis is a molecular biology technique that allows scientists to separate DNA fragments based on size. During gel electrophoresis DNA is mixed with ethidium bromide and run through a gel based on an electrical current.Answer and Explanation: The purpose of ethidium bromide in DNA ...
FimC and FimD are the chaperone and the usher, respectively, that facilitate the transport of the subunits to the bacterial surface. FimH, the adhesin tip, is integrated into the organelle structure with the help of adaptors, FimF and FimG. Although fimI is part of the operon, its function...
