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 ...

Two forms of the ubiquitous protein actin differ by only four amino acids but are dissimilar in 13% of their nucleotide coding sequences due to silent substitutions. A new study reveals that these ...

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 ...

CRISPR is a technology that can be used to edit genes and, as such, will likely change the world. The essence of CRISPR is simple: it’s a way of finding a specific bit of DNA inside a cell. After that ...

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 ...
