Core enzyme (without σ) does not specifically bind promoters, but rather dsDNA very tightly
• KD ≈ 5 x 10-12M t1/2 ≈ 60 minutes
• Holoenzyme binds non-promoter DNA more loosely
• KD ≈ 10-7M t1/2 > 1 sec

What is the subunit structure of the core RNA polymerase enzyme?
Core enzyme is composed of 2 alpha sub-units 2 beta sub-units (polymerase activity and clamp). Holoenzyme is the same with sigma factor attached which binds to prinbow box in mRNA.
How does the composition of the inner core and outer core explain the Dynamo theory?
Dynamo theory is the idea that a magnetic field generator exists within the Earth's outer core. It is this generator that explains the difference between the inner and outer core.
How does the composition of the inner and outer core explain this theory?
Dynamo theory is the idea that a magnetic field generator exists within the Earth's outer core. It is this generator that explains the difference between the inner and outer core.
What problem is overcome by the presence of more than one promoter element?
A. The transcription start site can be identified. B. The orientation of transcription can be established. C. Binding sites for both the core polymerase and holoenzyme are provided. D. The transcription bubble can be properly formed.
What is the difference between the Mohorovicic discontinuity and the Gutenberg discontinuity?
They mark the boundaries of differing layers of the Earth. The Moho marks the boundary between the crust and the mantle, whereas the Gutenberg discontinuity marks the boundary between the mantle and outer core.
What is the component of holoenzyme?
is a combination of a protein called a apoenzyme and one or more cofactors

What is the difference between the core and the lithosphere?
The difference between the core and the lithosphere is the core is on the top of the lithosphere and the lithosphere is on the bottom of the core

What is the difference between core and nucleus?
There is no difference. Both represent the same.
What is the difference between core and joint muscles?
Core muscles are in your core joint muscles are in your arms and legs
