cotranslational
This term is a highly specialized technical adjective used almost exclusively within molecular biology and biochemistry. It describes a precise temporal relationship where a biological event, such as protein folding or modification, occurs at the same time as the translation of mRNA into a polypeptide chain.
It is distinct from post-translational processes, which occur after the polypeptide chain has been fully synthesized and released from the ribosome. Because it describes a specific biochemical mechanism, it is typically paired with nouns like folding, modification, or translocation to specify exactly which event is happening during translation.
Ý nghĩa
Occurring or happening simultaneously with the process of translation, specifically referring to biological events that take place while a ribosome is synthesizing a polypeptide chain from an mRNA template.
The cotranslational folding of proteins ensures that the polypeptide reaches its functional three-dimensional shape as it emerges from the ribosome.
