olya-2409 [2.1K]

Answer:

The correct option is 3. "At pH 6.5 the enyzme is 50% active"

Explanation:

For the titratable group to be protonated and cause the enzyme to be in the active state, it needs to have gained a hydrogen cation (H+). In order for that to happen, there must be enough hydrogen cations in the environment of the enzyme, and hence, an acidic pH is required in this case.

Olin [163]

Answer:

nucleosomes = 1.65 x 10^6

H2a = 3.3 x 10^6 molecules

H2b = 3.3 x 10^6 molecules

H3 = 3.3 x 10^6 molecules

H4 = 3.3 x 10^6 molecules

Explanation:

It was mentioned in the book Principles of Genetics By D. Peter Snustad, Michael J. Simmons that in the nucleus of D. melanogaster there will be 1.65 x 10^6 nucleosomes and 3.3 x 10^6 molecules of every type of histone i.e. H2a, H2b, H3, and H4 present in it.
