What is the subunit structure of the core RNA polymerase enzyme?
The core RNA polymerase enzyme is composed of multiple subunits, typically consisting of five subunits in bacteria (α2ββ′ω) and twelve subunits in eukaryotes (Rpb1-12). These subunits work together to form the active site where RNA synthesis occurs.
How are the new strands of DNA lengthened?
New strands of DNA are lengthened through a process called DNA replication, which occurs during the S phase of the cell cycle. During this process, the enzyme DNA polymerase adds nucleotide units to the growing DNA strand, using the original strand as a template. This addition occurs in a 5' to 3' direction, as the enzyme can only attach nucleotides to the 3' end of the growing strand. Additionally, RNA primers are initially laid down to provide a starting point for DNA polymerase to begin synthesis.
SI unit of enzyme?
The SI unit of enzymes is not widely recognized, as enzymes are measured in activity units such as international units (IU) or micromoles per minute (µmol/min). The activity of an enzyme is typically based on its catalytic activity or the rate at which it catalyzes a specific reaction.
How do you you calculate the rate of enzyme activity?
The rate of enzyme activity can be calculated by measuring the amount of substrate converted to product over a specific time period. This is often expressed as the change in concentration of product per unit time (e.g., micromoles of product per minute). To quantify enzyme activity, you can use the equation: Rate = Δ[P]/Δt, where Δ[P] is the change in product concentration and Δt is the change in time. Enzyme activity can also be expressed in units such as enzyme units (U), which define the amount of enzyme that converts 1 micromole of substrate to product per minute under specific conditions.
What is the name of the enzyme that breaks down amylose?
The enzyme that breaks down amylose is called amylase. Amylase helps to hydrolyze the alpha-glycosidic bonds in amylose, breaking it down into smaller glucose units that can be utilized by the body for energy.

What are the units of the catalytic efficiency constant, kcat, in enzyme kinetics?
The units of the catalytic efficiency constant, kcat, in enzyme kinetics are per second (s-1).

What units are used to measure specific activity?
Specific activity is typically measured in units such as becquerels per gram (Bq/g) or curies per gram (Ci/g) in the context of radioactivity, or in units such as enzyme units per milligram (U/mg) in the context of enzyme activity.
How do you calculate specific activity of salivary amylase?
Specific activity of salivary amylase can be calculated by dividing the total enzyme activity (in units) by the total protein concentration (in mg). The formula is: Specific activity = Total enzyme activity (units) / Total protein concentration (mg). This calculation gives a measure of the enzyme's activity per unit of protein.

How do you subtract 6 percent from 1000 to get the whole number?
Percent means "out of 100", so subtracting 6 "out of one hundred" from 1000 means that we take away 6 units for every hundred units that exist. 1000=10x100 This means that there are 10 sets of 100 units in one thousand units. That means we need to take away 10 sets of 6 units. 10x6=60 6 units for each of 10 sets of 100 units yields 60 units. 1000-60=940 60 units less than 1000 units is 940.
Is dextrinase a protein enzyme?
Yes, dextrinase is a protein enzyme that specifically catalyzes the hydrolysis of dextrins into smaller glucose units. It plays a role in carbohydrate metabolism and is found in various organisms including bacteria, fungi, and plants.
What does 4 means in 42.368?
40 units
