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 ...

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

As many may know from the movie GATTACA, all DNA is composed of nucleotides containing one of four bases: A, C, G and T. These letters are the “blueprint” for life that has evolved over billions of ...

In a new study, stem cell scientists at the Lund University, Sweden, explore the role of non-coding regions of the genome—previously deemed to be functionless “junk” DNA—and find humans and ...

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 ...

Male mice grow ovaries instead of testes if they are missing a small region of DNA that doesn't contain any genes -- a finding that could help explain disorders of sex development in humans, at least ...

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 ...
