WebbIn eukaryotes, synthesis, cutting, and assembly of rRNA into ribosomes takes place in the nucleolus region of the nucleus, but these activities occur in the cytoplasm of prokaryotes. Neither of these types of RNA carries instructions to direct the synthesis of a polypeptide, but they play other important roles in protein synthesis.

Webb18 juli 2024 · Ribosomes are found outside the cell nucleus, either in the cell cytoplasm or attached to the rough endoplasmic reticulum; it is ribosomes that make the endoplasmic reticulum ‘rough’. A ribosome is split into two parts and the strand of mRNA runs through it like ribbon through an old-fashioned typewriter.

WebbFor cells to grow faster they must increase their protein production rate. Microorganisms have traditionally been thought to accomplish this increase by producing more ribosomes to enhance protein synthesis capacity, leading to the linear relationship between ribosome level and growth rate observed under most growth conditions previously examined. fabini psychotherapeutWebbThe ribosome comes and surrounds the mRNA of interest to be translated and then comes and attaches to the start codon.
