Answer:
a) DNA fragments associated with histone proteins are all multiple in length (i.e., 260 bp, 520 bp, 780 bp, etc), thereby suggesting the presence of a pattern of organization in the chromatin
b) it suggests that each unit of organization (ie, each nucleosome) consists of 260 bp associated with chromatin proteins
Explanation:
The nucleosome is considered as the basic unit of chromatin. A nucleosome consists of approximately two turns of DNA wrapped around a core of eight histone proteins (i.e., a histone octamer). The histone octamer consists of two copies of each of the histones H2A, H2B, H3, and H4. Moreover, the nucleosomes are connected together by linker DNA sequences which vary between 10 and 100 bp in length.
The value sign(x) equals −1, 0, or 1 depending upon whether the value x is negative, zero, or positive. Sometimes this is written as sgn(x) as is the case h
El signo de valor (x) es igual a -1, 0 o 1, dependiendo de si el valor x es negativo, cero o positivo. A veces esto se escribe como sgn (x) como es el caso h
The action by which a fluid enters the microhematocrit tube because of the attraction between the fluid and the tube is called capillary action.
There are different types of channels for blood flow that transport the blood pumped by the heart. They greatly differ only in the size of their diameters. Arteries are the big ones that are located mostly near the heart. Veins are the next which is where nurses inject you to gather blood. Then, the smallest ones are the capillaries.
To oxygenate your blood cells.
