This Escherichia coli cell has been treated with chemicals and sectioned so its DNA and ribosomes are clearly visible. The DNA appears as swirls in the center of the cell, and the ribosomes appear ...

Because they rely on hosts for a majority of functions, viruses aren’t considered alive. But entities like ‘Sukunaarchaeum ...

DNA is found in the nucleus, with a small amount of DNA also present in mitochondria. ... Messenger RNA (mRNA) copies portions of genetic code, a process called transcription, and transports these ...

The cell creates mRNA, a copy of DNA, to assemble proteins. The mRNA is then read by a different molecule known as a ribosome ...

Colliding ribosomes activate RNA repair Date: November 15, 2023 Source: Ludwig-Maximilians-Universität München Summary: Researchers discover how ribosomes contribute to the recognition and ...

When ribosomes go rogue Unusual variations in the cellular protein factory can skew development, help cancer spread, and more. But ribosome variety may also play biological roles, scientists say.

Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA ...

Ribosomes are molecular machines that translate messenger RNA (mRNA), which is transcribed from DNA, into proteins. Scientists have now learned more about ribosomes in nature, and their function. This ...

In nature, DNA containing D-nucleic acids is replicated and transcribed into RNA, which the ribosome translates into proteins containing L-amino acids. “It’s the fundamental operating system ...

Ribosomes getting stuck. The team also made an important discovery about ribosome collisions—where one ribosome runs into another due to a tricky RNA segment or differences in speed, for example.
