Suppose you are studying epigenetic modifications in the Genetics lab. You isolated the chromatin of Symbiodiniaceae from an anemone and used electron microscopy to examine the chromatin structure. You observed he chromatin structure is similar to ours, like beads on a string. After several tries of different techniques, you are able to analyze the core histones of the Symbiodiniaceae obtaining the following results:
Histone Percentage
H1 25%
H2A 12.5%
H2B 25%
H3 12.5%
H4 0%
H8
(new histone) 25%
Which of the following would you include in your lab report about the likely structure of the nucleosome in the chromatin of Symbiodiniaceae?
a. The nucleosome core contains a heterodimer of the histones H2A and H3
b. The nucleosome core contains two homodimers of each of histones H1, H2B, and H8
c. The nucleosome core contains one of each of histones H2A and H3
d. The nucleosome core contains more types of histones than our nucleosome core
e. The nucleosome core contains a homodimer of each of the histones H1, H2B, and H8
