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 ...

Transcription and translation are processes a cell uses to make all proteins the body needs to function from information stored in the sequence of bases in DNA. The four bases (C, A, T/U, and G in the ...

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 ...

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 ...

New research published in Nature Communications has linked a normal cellular process to an accumulation of DNA mutations in ...
