MicroRNAs (miRNAs) — a class of small RNAs with a role in the regulation of gene expression — had until now been found only in multicellular organisms. Now, Wang, Qi and colleagues provide the first ...
New work shows that physical folding of the genome to control genes located far away may have been an early evolutionary ...
This is a preview. Log in through your library . Abstract For unicellular organisms, a lack of effects of local species richness on ecosystem function has been proposed due to their locally high ...
Bacteria are among the smallest living things. A single bacterium consists of just one cell. Not all bacteria are harmful. There are different unicellular organisms and types of bacteria. Yeast are ...
At some point, organisms changed and grew from a single cell into one made up of many cells. But how that happened is not well understood. New work by graduate candidate Jonathan Featherston of the ...
An international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular ...
Bacteria are among the smallest living things. A single bacterium consists of just one cell. Not all bacteria are harmful. There are different unicellular organisms and types of bacteria. Yeast are ...
Scaling up from one cell to many may have been a small step rather than a giant leap for early life on Earth. A single-celled organism closely related to animals controls its life cycle using a ...
Tumors of distinct tissues of origin and genetic makeup display common hallmark cellular phenotypes, including sustained proliferation, suppression of cell death, and altered metabolism. These ...
Images of the multicellular development of the ichthyosporean Chromosphaera perkinsii, a close cousin of animals. In red, the membranes and in blue the nuclei with their DNA. The image was obtained ...
Marine bacteria normally seen as single cells join together as a “microscopic snow globe” to consume bulky floating carbohydrates. Close your eyes and imagine bacteria. Perhaps you’re picturing our ...
A team of scientists, led by the University of Sheffield in the UK and Boston College in the U.S., has found a microfossil in the Scottish Highlands which contains two distinct cell types and could be ...
