This narrated animation illustrates the process of protein synthesis, starting with chromosomal DNA inside the cell's nucleus. A gene is transcribed into messenger RNA, which leaves the nucleus and ...

How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. But ...

Proteins are essential biological molecules that perform a vast array of functions crucial for life, from catalyzing ...

Michael Buck, PhD, professor of biochemistry in the Jacobs School, recently received NIH funding to explore how molecular readers of DNA access and activate seemingly hidden genes.

The origins of millions of tiny proteins in our bodies, previously assumed to be useless, have now been discovered. A study published on February 17 in the journal Molecular Cell describes how these ...

In October 1990, biologists officially embarked on one of the century’s most ambitious scientific efforts: reading the 3 billion pairs of genetic subunits — the A’s, T’s, C’s and G’s — that make up ...

Telomeres are repetitive sequences of DNA that can be found at the ends of chromosomes, where they form a kind of protective cap. Telomeres get shorter every time a cell divides, and they are thought ...

One might think that the primary cause of most genetically linked diseases comes from mutations in coding DNA -- alterations in coding regions of the genome that can lead directly to changes in the ...

Epigenome editing has followed a similar path, in that more recent technological breakthroughs have enabled scientists to apply the discoveries made in previous decades. Epigenome editing performs a ...

Penny Riggs has received funding from the United States Department of Agriculture National Institute for Food and Agriculture and the National Science Foundation. DNA is found inside the cells of ...
