Compare and contrast two mechanisms for transcriptional termination in bacteria.
(rho)p-dependent termination: requires rut (rho utilization site), rho protein binds, moves towards 3' end, DNA encodes GC rich for stem loop, RNApoly pauses, rho protein catches up and separates RNA-DNA hybrid
(rho)p-independent termination: Uracil-rich sequence causes RNApoly to pause, stabilized by NusA near open complex RNA exit, UA bonds to weak to hold, DNA-RNA hybrid dissociates AKA intrinsic termination
hope this help
Chloroplasts (takes in the sun's energy to make food for the plant). Cell membrane (It helps the plant stand up because plants don't have spines like us).
A substrate because substrates go to the active site on an enzyme.
I believe they are called “push” factors. They prevented people from wanting to stay in the current area, and were “pulled” by factors in the US as it offered more opportunities.
Lipids that make up our cell membranes are phospholipids, and they're awfully similar to soap. They consist of glycerol<span> attached to a phosphate group and to two </span>fatty acids<span>, or carboxylic acids.</span>
