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.
And the sphere of energy that is centered around the two sets of tetrahedrons forms with the disk to create a shape that looks like a FLYING SAUCER around the body. This energy matrix is called the MER-KA-BA. However, it is not stable. If you see or sense the MER-KA-BA around you at this point, you will know it to be unstable.
