WebDNA in the cytoplasm DNA in mitochondria A scientist is studying a cell and can clearly see that it has ribosomes and mitochondria. Which statement best describes how the cell could be classified? The cell is prokaryotic because it contains ribosomes. The cell is prokaryotic because it contains mitochondria. WebApr 12, 2024 · Ribosomes are downregulated in arrested cells leading to increased cytoplasmic diffusion. We hypothesized that growth attenuation was caused by a reduced cellular ribosome content because ribosomes are rate-limiting for growth in proliferating yeast cells (Metzl-Raz et al., 2024).To test this hypothesis, we measured the protein and …

WebRibosomes are found free in the cytoplasm or on the surface of rough endoplasmic reticulum. They may exist singly or form chains (polyribosomes). Ribosomes serve as the site of protein synthesis. This is accomplished with transfer RNA (tRNA) for amino acid transport to the ribosome, and specific mRNA molecules.
