Each day, a human adult loses on average 50 to 70 billion cells, which die from natural causes alone. New cells replace lost ...

Heidelberg biochemists and structural biologists from Shanghai unravel the roles of two key regulatory factors in mRNA ...

Two molecular control factors play a decisive role in what is known as splicing, the cutting and assembly of mature messenger ...

It begins with observing onion cells, highlighting their components such as the cell wall, nucleus, and vacuoles. Staining techniques reveal the protoplasm, which is essential for life.

As warehouses go, nuclei are more like libraries than bank vaults. Too many cellular components need access to the genome to lock it down like Fort Knox. Instead, large groupings of more than 1,000 ...

Northwestern Medicine scientists have uncovered new details about the genetic structure of ovarian cancer stem cells, ...

Wenzhou Medical University and collaborating institutions have identified a population of human neural retinal stem-like ...

It diffuses into the nucleus, where the genome resides, through large pores. There, enzymes break down the metabolites into epigenetic marks known as acetyl groups and place them on histones to ...

Purdue University scientists have discovered a key mechanism that regulates how plants develop chloroplasts, essential ...

Viruses known as “jumbo phage” are a new hope against the rising antibacterial infection crisis. Researchers have discovered ...

At first glance, it looked like a genetic error — so severe it should have crippled the animal. But instead, it helped turn ...
