TFIIE -80 to +30 For bacterial RNA polymerase, only the sigma factor is needed for the enzyme to recognize the promoter. The eukaryotic transcription factors may indeed act as sigma factors to allow the eukaryoitic RNA polymerase to recognize the promoter.
An energy pyramid is the graphical representation of the trophic levels (nutritional) by which the incoming solar energy is transferred into an ecosystem.The source of energy for living beings on Earth is the Sun.The energy that the Sun emits at present is of 1366.75 W/m^2 (400 years ago, it was of 1363.48 W/m^2).n energy pyramid is the graphical representation of the trophic levels (nutritional) by which the incoming solar energy is transferred into an ecosystem.
the energy that is stored in the centre of an atom is called a neutron. the proton helps the neutron to store itself in the center. The electron is around it.Which is known â¦ as nuclear energy. 1  The Periodic Table of Elements Life is sustained by a number of chemical elements.here are two types of energy stored in atoms: electrical and nuclear. Nuclear energy is stored within an atom's nucleus, while electrical energy is the flow of electrons. In â¦ addition, the bonds between atoms in a molecule store chemical energy. 1 person found this useful.
