However, in certain cases, the activity of these pathways can lead to aberrant DNA repair, genomic instability and tumorigenesis. One such case is DNA repair at the natural ends of linear chromosomes, known as telomeres, which can lead to chromosome-end fusions. Here, we review data obtained ...
aberrant gene expression resulting from disrupted HAT and HDAC activities can alter immune responses or neuronal signaling, leading to disease. Thus, the role of histone acetylation in regulating gene expression is critical across a wide spectrum of biological...
DNA molecules are long — so long, in fact, that they can't fit into cells without the right packaging. To fit inside cells, DNA is coiled tightly to form structures calledchromosomes. Each chromosome contains a single DNA molecule, wrapped tightly around spool-like proteins called histones, ...
In addition, two distinct types of enzymatic complexes facilitate binding of transcription factors to nucleosomal DNA. These include type A histone acetyltransferases (e.g. GCN5/ADA transcriptional adaptor complex) and ATP-driven molecular machines that disrupt histone-DNA interactions (e.g. SWI/SNF ...

What is the difference between DNA, chromatin, and chromosomes and what is the significance of each form? (a) What are the different types of DNA polymerase in prokaryotes and eukaryotes? (b) What are their functions? What are the enzymes involved in DNA replication in prokaryotes? Give the...
What is a histone? What is redundancy in an organization? What is cognitive linguistics and what are some major pedagogical implications for the classroom? What types of subjects, issues, or events would be of interest to sociologists?
Duvyzat is a histone deacetylase (HDAC) enzyme inhibitor approved for the treatment of Duchenne muscular dystrophy (DMD) in patients 6 years of age and older. By inhibiting HDACs, Duvyzat slows DMD disease progression, increases muscle mass and reduces muscle tissue necrosis. ...
Chromosomes are contained within the nucleus in eukaryotic cells, but can also be found in some of the other organelles such as mitochondria (where DNA is packed into a small circular chromosome). In prokaryotes (e.g. bacteria), on the other hand, chromosomes form the nucleoid that is ...
DNA in vivo is often sharply distorted away from the canonical Watson–Crick structure; different DNA sequences vary greatly in the ease with which such sharp distortions can be accommodated. Most of the eukaryotic genomic DNA is bent around histones to form nucleosomes. The capacity of the DNA...
