Biophysicist Seham Ebrahim of the University of Virginia and her team of researchers were observing mammalian cells when they ...

It has been known for several years that abnormal chromosome numbers lead to protein imbalances in the affected cells. Researchers at RPTU have now investigated the detailed effects of such imbalances ...

Following extensive evidence for the formation of four-stranded DNA G-quadruplex structures in vitro, DNA G-quadruplexes have been observed within human cells. Although chemically distinct, RNA ...

Human cells are made up of the following: a cell nucleus, which contains the genetic material in the form of DNA; and the cytoplasm, where proteins are built.

Mitochondrial DNA: Human mitochondrial DNA consists of 6,569 DNA base pairs and, unlike the chromosomes found in the nucleus, the mitochondrial genome is circular. Mitochondria function. Below we take ...

Human Hormones and Their Functions. Hormones are chemical messengers that influence various body functions, including reproduction, ... Steroid hormones and amine hormones interact with receptors in ...

University of Virginia scientists discover new cell organelle called "hemifusome" that helps manage cellular recycling.

Different classes of RNA molecules are synthesized in the eukaryotic nucleus and are exported through nuclear pore complexes to the cytoplasm by mobile export receptors. Small RNAs follow ...

Their main function is to generate the energy necessary to power cells, but they are also involved in cell signaling and death. Present in nearly all types of human cells, mitochondria are vital ...

Created by integrating six different imaging techniques, the images show thread-like cytofilaments reaching into and traversing a human breast cell's chromatin-packed nucleus. Skip to main content ...

The balls of cells that IVF clinics transfer into the uteruses don’t yet have the “elements fulfilling extra-embryonic and uterine functions” described by Rivron and colleagues. Those ...

A further understanding of the organelle could pave the way for better treatment of genetic and neurodegenerative diseases.
