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.

What is the structure of mercury?
rock over an iron core. no atmosphere.
What is the only part of earths inner structure that is a liquid?
The inner and outer core are made mostly of molten rock and lead, as the very center is solid because of the constant force. The thick mantle is liquid towards the center and is primarily considered to be solid. The outer core is what I would say to be the "only" liquid layer in Earth's structure as the inner core has too much pressure and the mantle had too little heat.
What are the major layers of earths internal structure based on physical properties?
inner core outer core lower mantle upper mantle lithosphere
What is Difference between holoenzyme and core enzyme?
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 Basic structure of earths inner core?
The inner core is chiefly formed of an alloy of Iron and Nickel with many many other elements occurring in trace amounts
Which enzyme is used specifically for rna transcription from dna in nucleus?
RNA polymerase.... What a wonderful, uplifting speech she gave at the convocation memorial service at Va Taech the day after the shootings there. She raised the spirits of both the students and the staff along with those of the world. She gave hope to the hopeless of the world and raised every single person involved with Va Tech to the highest of all highs. Va Tech is indeed lucky to have her as one of their professors. I hope and pray that they all recover from this horrible tragedy and with staff like her, the students will prevail! Go Hokies! Go Hokies!
How are eubacteria different from archaebacteria?
Eubacteria are true bacteria. They:-contain peptidoglycan in cell wall-straight-chain ester-linked lipids in cell membrane-four subunit RNA polymerase core-some are pathogenicThe classification archaebacteria is outdated. Archaea are separate from bacteria because they have unique characteristics. They:-lack peptidoglycan in cell walls-branched-chain ether-linked lipids in cell membrane-can obtain energy through methanogenesis-lipid stereochemistry is opposite of that in other organisms-lack thymine in tRNA-ten subunit RNA polymerase core-none are pathogenicEubacteria and archaebacteria have similar general cell structures, but the composition and layout of those cellular components is remarkably different.
What is an organic catalyst with a protein core?
enzyme
What are the internal structure of the earth?
the mantle the outer core and the inner core
What has the author H A Core written?
H A. Core has written: 'Wood structure and identification'
What are the main layers the form the earth's structure?
The Inner core, outer core, mantle, and crust.
What is the component of holoenzyme?
is a combination of a protein called a apoenzyme and one or more cofactors
What is the structure of rabies?
According to the Center of for Disease Control and Prevention, rhabdovirues are about 180nm in length and 75 nm wide. Five proteins: nudeoprotein, phosphoprotein, matrix protein, glycoprotein and polymerase encode the rabies genome. Two major components : a helical ribonucleoprotein core and a surrounding envelope make up all rhabdoviruses
How is the structure of earth and the structure of a peach similar?
Sorry. The earths core reminds me of an apple. So here goes. In the center of the apple, there is a core, and that is the hardest a biggest part. So that is the earths core. The crust is the skin of the apple, and that is also the thinnest. The rest is the outer core and mantle.
What is the structure of mercury?
rock over an iron core. no atmosphere.
The core is how far beneath Earth's surface?
To be precise, there is actually an outer core and an inner core. You can find the details in the Wikipedia article "Structure of the Earth".
What is it outer core or inner core?
the outer core is the liquid layer of the earth's internal structure moving downwards fr the lower mantel while the inner core is solid layer of the earth's core composed of iron nickel alloys
