Concept explainers
Interpretation:
The explanation, with the help of a diagram, of the acetylation or phosphorylation of histones that could change their binding affinity with the DNA.
Concept Introduction:
Histones are the basic proteins that are found complexed with the DNA (deoxyribonucleic acid). They help in the packaging of the DNA, and their complex is known as chromatin. There are four types of histones named H2A, H2B, H3, and H4. Two molecules of each of these proteins are joined to form a histone octamer.
The histone octamer with the wrapped DNA is termed as nucleosome, and several nucleosomes connected by H1 histones form the chromatin. The string portion is termed as spacer region. There are about 150 base pairs of DNAs wrapped around one octamer, and the spacer or linking region contains about 30 to 50 base pairs.

Use the mechanism to predict the two products generated.arrow_forwardShow the mechanisms of PGK and PFK-1. How are they different?arrow_forward
- Show the fate of the proton on the 4-Oxygen molecule of F-1,6-BP.arrow_forwardSodium borohydride (NaBH4) is a potent inhibitor of aldolase. It is known to ONLY inhibit theenzyme when it is complexed with substrate. Treatment of the enzyme alone has no effect.What is the mechanism for this inhibition?arrow_forwardA non-hydrolysable ATP (AMPPNP - below) is ingested by a graduate student on a dare. Whateffects would you anticipate on his metabolism?arrow_forward
