The acetyl group counteracts the positive charge of the epsilon-amino group of the lysine, reducing the overall charge of histones, and decreases their affinity for the negatively charged DNA.
Both PTMs reduce the overall charge of histones and decrease their affinity for the negatively charged DNA, leading to chromatin opening and facilitation of recruitment of the transcriptional machinery [ 22].
For example, when a neutron transmutes into a proton, it emits a W−; thus, the overall charge remains zero before and after the decay process.
The agent told the Guardian sellers were currently paying a reduced fee to use the process – £150 plus VAT – so the overall charge was not larger than on a sale made through the traditional process.
Others who are aligned to Walsh say the position is "horrific" because of the level of criticism, the growing divisions and the overall charge that the club has moved away from what it used to stand for.
The overall charge of bacterial cell walls is negative.
At the stochiometry condition, when the overall charge of the polyion equals the overall charge at the particle surface, the size of the aggregates reaches its maximum value.
Thus, the overall charge of the molecule has a major impact on the partitioning behavior.
The charge of each functional group contributes to the overall charge of the surface.
Charge transfer reaction 1 was found to dominate the overall charge transfer reaction under cathodic polarization.
Their contribution to the overall charge depends on the experimental conditions.
