The genetic information stored in DNA is a living archive of instructions that cells use to accomplish the functions of life. Inside each cell, catalysts seek out the appropriate information from ...

HHMI scientists and their colleagues discover a new mechanism of protein synthesis. Ribosomes are the cell’s molecular machines, responsible for translating genetic information in messenger RNA into ...

The table below list organelles, their function and the types of cell that they can be found in. Can you fill in the blanks to complete the table? Cell structure Description Function Cell type ...

The research field of 'cellular IRESes' lay dormant for decades, as there was no uniform standard of reliable methods for the clear characterization of these starting points for the ribosome-mediated ...

Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...

To manufacture protein molecules, a cell must first transfer information from DNA to mRNA through the process of transcription. Then, a process called translation uses this mRNA as a template for ...

Bacteria modify their ribosomes when exposed to widely used antibiotics, according to research published in Nature Communications. The subtle changes might be enough to alter the binding site of ...

Northwestern Medicine scientists have uncovered new details explaining how poxviruses manipulate host cells to enhance their own protein production, according to a study published in Cell Reports.

During translation, multiple ribosomes travel along the nucleic acid chain to build polypeptides that become functional proteins. Occasionally, these molecular decoders pause on the mRNA, either ...

A previously unknown kind of ribosome is responsible for folding sperm proteins, which decay before fertilization if prepared by other ribosomes. Dan is a News Editor at The Scientist. He writes and ...

Only recently has the ribosome - one of the oldest molecular machines in evolutionary terms - been recognized as an active regulator of gene expression at the level of protein biosynthesis.
