Solved Histone acetylation and GR expression: Histone - Chegg
Histone acetylation and GR expression: Histone acetylation at the lysine-9 (K9) amino acid (residue) of histone H3 protein (Acetyl H3K9) is a marker of active chromatin and transcriptional activity. The figure below (Figure 4) shows the levels of H 3 − K 9 acetylation association and NGFI-A binding to the GR promoter when comparing high-LG ...

Solved In contrast to histone acetylation, which always - Chegg
In contrast to histone acetylation, which always correlates with gene activation, histone methylation can lead to either transcriptional activation or repression. How do you suppose that the same modification - methylation - can mediate different biological outcomes? Explain what is meant when we say two DNA sequences are 'highly conserved'.
Solved Altered histone acetylation patterns have been - Chegg
Altered histone acetylation patterns have been observed in aging tissues and are associated with age-related maladies such as cancer, neurodegeneration, and others. Studies have found that histone acetylation decreases with age in mice, resulting in diminished expression of genes related to learning and memory.
Solved What general role does acetylation of histone protein
Histone acetylation events are most often associated with transcription termination. What general role does acetylation of histone protein amino acids play in the transcription of eukaryotic genes? Histone acetylation events are most often associated with transcription repression.
