What protein molecules does DNA wrap around to form a nucleosome

Chemistry
1 answer:
Delvig [45]3 years ago
4 0

Answer:

Histone proteins.

Explanation:

Histones are known as the special type of proteins which are +ve charged and low molecular in weight. They are highly basic proteins and containing basic amino acids such as arginine and lysine. Histones are +ve charged proteins and DNA is -ve charged in nature, due to the presence of phosphate groups in DNA backbone, histones bind with DNA very tightly and form a complex known as Nucleosome.

The Nucleosome is known as the fundamental unit of DNA packaging which is composed of an Octameric core of histone proteins (two each of histones H2A, H2B, H3, and H4) around which the double helix of DNA is wrapped.

Calculate the concentration of a solution that has 6.7 moles in a volume of 0.6 liters.
Yuri [45]

Answer:

11.2 M

Explanation:

Given data:

Number of moles = 6.7 mol

Volume of solution = 0.6 L

Concentration /Molarity = ?

Solution:

Molarity:

It is number of moles of solute in to per kg or litters of solution. It can be calculated by the following formula.

Molarity = number of moles / Volume in L

Now we will put the values in formula.

Molarity = 6.7 mol / 0.6 L

Molarity = 11.2 mol/L

Molarity = 11.2 M

Use the balanced equation given below to solve the following problem; Calculate the volume in liters of CO produced by the react
Elan Coil [88]

Answer: 40.3 L

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}

\text{Moles of} Sb_2O_3=\frac{175g}{291.5g/mol}=0.600moles

Sb_2O_3+3C\rightarrow 2Sb+3CO  

According to stoichiometry :

1 moles of Sb_2O_3 produces = 3 moles of CO

Thus 0.600 moles of Sb_2O_3 will produce=\frac{3}{1}\times 0.600=1.80moles  of CO

Volume of CO=moles\times {\text {Molar volume}}=1.80moles\times 22.4L/mol=40.3L

Thus 40.3 L of CO is produced.

Explain the significance of this quote, “Heisenberg may have slept here.”
ch4aika [34]

Umm...Well...

Heisenberg's Uncertainty Principle says that we can never know both the position and rate of change of a particle at any time. We can only know one or the other. This leads to rather silly jokes that deal with uncertainty, probability, and superposition. So, saying that "Heisenberg may have slept here" is essentially saying that it is uncertain if Heisenberg slept there or not, making for a rather silly, but slightly unfunny physics joke.
