Ribosomal subunits of eukaryotes
The ribosome is a complex cellular machine. It is largely made up of specialized RNA known as ribosomal RNA (rRNA) as well as dozens of distinct proteins (the exact number varies slightly between species). The ribosomal proteins and rRNAs are arranged into two distinct ribosomal pieces of different sizes, known generally as the large and small subunit of the ribosome. Ribosomes consist o… Webb13 apr. 2024 · Sucrose-density gradient ultracentrifugation was used to fractionate the free pool, ribosomal subunits, monosome, and polysomes. a Optical density profiles (Abs …
