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 … WebThe Transcription Process RNA molecules are created during a process called transcription. This process uses the enzyme RNA polymerase to transcribe segments of DNA into complementary RNA molecules. First the RNA polymerase binds to a promoter region of the DNA to initiate transcription.
