Sensing bacterial communication

They may not have mouths or even vocal chords, but tiny organisms do communicate with one another. A Florida Tech study may give researchers and students further insight into that process.

Advances in research on the most general type of stem cells

Stem cell research is the prerequisite for regenerative medicine, which with the help of the body's cells recreates and heals important organs. Now, researchers at Karolinska Institutet, SickKids in Canada and KU Leuven in ...

New drug inhibits the growth of cancer cells

A newly developed compound starves cancer cells by attacking their "power plants"—the so-called mitochondria. The new compound prevents the genetic information within mitochondria from being read. Researchers from the Max ...

A one-stop shop for analyzing algal genomes

Interested in the genomes of algae? You now have one place where you can browse the genetic blueprints of these photosynthetic organisms. PhycoCosm is one of the largest data repositories of its kind, with an interactive ...

The DNA regions in our brain that contribute to making us human

With only 1% difference, the human and chimpanzee protein-coding genomes are remarkably similar. Understanding the biological features that make us human is part of a fascinating and intensely debated line of research. Researchers ...

RNA molecules are masters of their own destiny

At any given moment in the human body, in about 30 trillion cells, DNA is being "read" into molecules of messenger RNA, the intermediary step between DNA and proteins, in a process called transcription.

New data on 'jumping genes' linked to cancer

Scientists from the University of Granada and GENYO have discovered a mechanism via which our cells protect themselves against these transposable or mobile genetic elements, known as "LINE-1," which are involved in the development ...

Gene expression

Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding genes such as rRNA genes or tRNA genes, the product is a functional RNA.

Several steps in the gene expression process may be modulated, including the transcription, RNA splicing, translation, and post-translational modification of a protein. Gene regulation gives the cell control over structure and function, and is the basis for cellular differentiation, morphogenesis and the versatility and adaptability of any organism. Gene regulation may also serve as a substrate for evolutionary change, since control of the timing, location, and amount of gene expression can have a profound effect on the functions (actions) of the gene in the organism.
