It would be a major modification that would impair the universal value of the park," said Leila Maziz, the coordinator for the Congo Basin projects at Unesco.

During the S-phase, chromatin undergoes major structural modifications that are inherent to DNA replication [32].
Methylation is one of the major epigenetic modifications that repress transcription in vivo.
Ubiquitination is one of the major protein modifications that occur in all eukaryotic cells, and is critical for the regulation of various cellular functions, such as DNA damage repair, endocytosis, endosomal sorting, and signal transduction, in addition to proteolysis by the 26 S proteasome [ 12].
To this purpose, proteomics studies are a powerful tool to better understand where to set the boundary line of healthy aging and age-related disease by analyzing the variation of protein expression levels and the major post translational modifications that determine "protein" physio/pathological fate.
DNA methylation is the major epigenetic modification that involves alterations of chromatin structure.
DNA methylation is a major epigenetic modification that is vital to mammalian development [ 1].
DOI: http://dx.doi.org/10.7554/eLife.00726.002 DNA methylation is an ancient and major epigenetic modification that plays an important role in key biological processes, including genomic imprinting, X-chromosome inactivation, suppression of transposable elements, and carcinogenesis (Jaenisch and Bird, 2003; Egger et al., 2004; Robertson, 2005; Feinberg, 2007; Reik, 2007).
The major modification is that particles impacting on collectors or already deposited particles may bounce off and escape collection if the impact velocity is great enough.
