Latest Histone H3 Stories
The function of histones -- the proteins that enable yards of DNA to be crammed into a single cell -- depends on a number of chemical tags adorning their exterior.
The genetic inherited material DNA was long viewed as the sole bearer of hereditary information.
A study from the University of North Carolina at Chapel Hill has identified a key player in a molecular process essential for DNA replication within cells.
An Emory University study shows some of the first direct evidence of a process required for epigenetic reprogramming between generations â€“ a finding that could shed more light on the mechanisms of fertilization, stem-cell formation and cloning.
The Stowers Institute's Workman Lab has discovered a novel histone demethylase protein complex characterized in work published today in Molecular Cell.The Histone H3 protein is an important component of chromatin, the packing material wrapping up chromosomal DNA and preventing unwanted transcription of the message encoded in the DNA. Histone H3 can be altered by adding (methylating) or removing (demethylating) methyl groups from the histone protein. When genes are transcribed, parts of...
Scientists at the University of North Carolina at Chapel Hill have identified a molecular protein's critical role in cell division and growth.
Identical twins are often remarkably similar, yet they have distinct differences. This might seem unexpected since they share all of the same genes, but scientists have come up with an explanation.
- A handkerchief.
- Specifically— The legendary sweat-cloth; the handkerchief of St. Veronica, according to tradition miraculously impressed with the mask of Christ; also, the napkin about Christ's head (Johu xx. 7).
- In general, any miraculous portrait of Christ.
