The method to the dengue virus's maddening infectiousness.
Long non-protein-coding RNA (lncRNA) sequences are often transcribed from the opposite, or antisense, strand of a protein coding gene. In the past few years, research has shown that these lncRNAs play a number of regulatory roles in the cell. For exa

Telomeres are repetitive, noncoding sequences that cap the ends of linear chromosomes. They consist of hexameric nucleotide sequences (TTAGGG in humans) repeated hundreds to thousands of times. Telomeres protect the protein-coding sequences of DNA on
A transition-state mimic has the power to bind an enzyme at its tipping point as strongly as any available inhibitor and more strongly than most, preventing enzymatic activity. In order to replicate the structure of an enzyme’s transition state, whic
Vitamin D has a variety of actions in the body. It binds to the vitamin D receptor (VDR), which then binds to the retinoid X receptor (RXR) and activates the expression of numerous genes. Through this mechanism, vitamin D promotes calcium absorption
In fewer than 15 years, nanomedicine has gone from fantasy to reality.
Isolating specific cell types from a mass of plant or animal tissue is laborious and tricky. To study epigenetic changes and genes that are expressed differently in different cell lineages—such as cancer cells versus normal cells, or the two types of
When someone snorts or smokes cocaine, which is composed of small crystalline alkaloid molecules, the drug enters the bloodstream and from there eventually crosses into the heart, brain, and other organs. Cocaine quickens heart and respiratory rates,
