Nucleosomes are the basic packing unit of DNA built from histone proteins around which DNA is coiled. They serve as a scaffold for formation of higher order chromatin structure as well as for a layer of regulatory control of gene expression.

Answer:
The three types of nuclear radiation in increasing order of penetrating power are ____.
alpha, beta, gamma
Explanation:
Alpha Ray: This has the least penetrating power because the particles produced during decay are large in quantity but they have a very low energy which dosent alow them to move far through space because the are ususally blocked.
Beta ray : they have more penetrating power than alpha rays because they a bit higher in energy and quantity {size}
Gamma Ray; this has the most penetrating power. they are highly powerful waves but do little at ionization of other atoms or molecules. it penetrates through molecules very easily due to its size and energy.
Answer:
2.2mL
Explanation:
First, let us analyse what was given from the question:
C1 = 2.09M
V1 =?
C2 = 0.046M
V2 =100mL
Using dilution formula (C1V1 = C2V2), we can calculate the volume of the original solution as follows:
C1V1 = C2V2
2.09 x V1 = 0.046 x 100
Divide both side by the coefficient of V1 ie 2.09, we have:
V1 = (0.046 x 100) / 2.09
V1 = 2.2mL
