Why is Ribosome Involved in Protein Synthesis

Webb31 mars 2024 · While DNA is responsible for storing genetic information, mRNA directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins. While DNA completes all of its functions staying in the nucleus, mRNA’s smaller size allows it to travel from the nucleolus to the cytoplasm. WebbRibosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not … WebbThese proteins regulate pre-rRNA synthesis, cleavage, post-transcriptional modifications, ribosome assembly, and export (Chauvin et al 2013). This was largely mediated through phosphorylation of S6, as mice expressing a nonphosphorylatable S6 had a deficit in the up-regulation of these proteins (Chauvin et al 2013) .…” heymanns patentanwälte
