WebMay 7, 2024 · The translation is the second part of the central dogma of molecular biology: RNA --> Protein. It is the process in which the genetic code in mRNA is read to make a protein. The translation is illustrated in Figure 6.4. 6. After mRNA leaves the nucleus, it moves to a ribosome, which consists of rRNA and proteins. WebRibosomes comprise two subunits (Fig. 1), one large and one small, with both subunits made up of ribosomal RNA (rRNA) and proteins. These rRNA molecules are synthesized by the nucleolus inside the nucleus and combined with proteins. The assembled subunits exit the nucleus to the cytoplasm.

WebA microtubule is made up of tubulin proteins arranged to form a hollow, straw-like tube, and each tubulin protein consists of two subunits, α-tubulin and β-tubulin. Microtubules, like actin filaments, are dynamic structures: they can grow and shrink quickly by the addition or removal of tubulin proteins. rhys orsonWebSep 30, 2024 · Bacterial ribosomes.
