WebA ribosome is basically a very complicated but elegant micro-‘machine’ for producing proteins. Each complete ribosome is constructed from two sub-units. A eukaryotic ribosome is composed of nucleic acids and about 80 … WebThe ribosome is responsible for translating the mRNA into protein. A. The ribosome consists of a large and small ribosomal subunit. Assembly of the subunits on the mRNA forms three tRNA binding sites. B. During translation, charged tRNAs enter the Acceptor site, and the …
WebApr 3, 2024 · This work indicates that oxaliplatin induces a distinct DDR signaling pathway that functions in trans to inhibit Pol I transcription in the nucleolus, demonstrating how nucleolar stress can be linked to DNA damage signaling and highlighting an important mechanism of Pt drug cytotoxicity.
