In eukaryotes, the tight or loose packaging of the genes in chromatin (DNA plus specific proteins) can control whether the genes can be expressed to form their encoded product. Chromatin is usually ...
Highly repetitive regions of junk DNA may be the key to a newly discovered mechanism for gene regulation. The discovery during the Human Genome Project in the early 2000s that we humans have only ...
Researchers turned programmable proteins into a novel genetic tool, potentially enabling tighter control of gene expression. LacI is a tetrameric protein, using two dimers to bind two specific, ...
