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.
Answer:
The independent variable is the underlying conditions (x-axis) and the dependent variable is the percentages (y-axis)
Answer:
the heart
Explanation:
the heart pumps blood through the body
Hydrocephalus is the condition were there is excess of CSF in ventricles or subarachnoid space
Answer:
Yes they show difference in their mobility due to the difference in their molecular weight.
Explanation:
GFP is green fluorescent protein and BFP is blue fluorescent protein that are used in recent molecular techniques. Gel electrophoresis can be used to understand the molecular weight of protein based on their mobility.
The GFP and BFP have 238 amino acids but two amino acids have been substituted that found in the GFP primary structure. The GFP band in G-Boil and BFP band in B-Boil shows different location. The substitution of two amino acids reduces the molecular weight of the protein. The protein with less molecular weight shows high mobility in the gel.
