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 type of organic macro molecule is in enzyme?
Enzymes are primarily composed of proteins, which are a type of organic macromolecule. Proteins are made up of long chains of amino acids that fold into specific three-dimensional shapes, allowing them to catalyze biochemical reactions. While some enzymes can also contain non-protein components called cofactors or coenzymes, the core structure of an enzyme is a protein.
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 is a core sheath fiber section?
A core sheath fiber section refers to a type of fiber structure where a central core is surrounded by a sheath or outer layer. This configuration can provide specific properties such as enhanced strength, durability, or flexibility compared to a uniform fiber structure. Core sheath fibers are commonly used in various applications such as textiles, composites, and technical fabrics.
What is RNA polymerase made of?
RNA polymerase is a complex enzyme composed of multiple protein subunits. In bacteria, the core enzyme is made up of five subunits, while the holoenzyme includes additional subunits for promoter recognition and regulation. Eukaryotic RNA polymerases have multiple subunits that work together to transcribe DNA into RNA.
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!
What is a subunit of a steroid?
A subunit of a steroid refers to the smaller molecular components that make up the steroid structure. Steroids are typically composed of a core structure of four fused carbon rings, known as the steroid nucleus, along with various functional groups and side chains that modify their properties and functions. These subunits can include different types of hydrocarbon chains, hydroxyl groups, or other functional groups that influence the steroid's biological activity and solubility.
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
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 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 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
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".
