Protein synthesis is the process by which cells build proteins using the information encoded in genes. Here is a synthesis of the information based on the provided search results:

  1. Overview of Protein Synthesis: Protein synthesis is a core biological process that occurs inside cells. It involves the production of new proteins to balance the loss of cellular proteins through degradation or export Proteins perform critical functions in cells as enzymes, structural proteins, or hormones.

  2. Transcription and Translation: Protein synthesis can be broadly divided into two phases: transcription and translation. During transcription, a section of DNA encoding a protein, known as a gene, is converted into a template molecule called messenger RNA (mRNA). This conversion is carried out by enzymes called RNA polymerases. In eukaryotes, the mRNA is initially produced in a premature form (pre-mRNA) and undergoes post-transcriptional modifications to become mature mRNA. The mature mRNA is then exported from the nucleus to the cytoplasm.

  3. Role of mRNA: Messenger RNA (mRNA) carries the protein-coding information from the DNA in the nucleus to the cytoplasm, where the protein-making machinery reads the mRNA sequence. Each three-base codon in the mRNA corresponds to a specific amino acid, and the ribosome translates the codons into an amino acid sequence, forming a growing protein chain.

  4. Energy Requirements: Protein synthesis is an energy-consuming process. It requires the utilization of energy-rich molecules, such as adenosine triphosphate (ATP), to drive the assembly of amino acids into polypeptide chains.

  5. Regulation of Protein Synthesis: Protein synthesis is tightly regulated in cells. Various factors, including nutrient availability, energy status, and signaling pathways such as the mammalian target of rapamycin complex 1 (mTORC1), play a role in modulating protein synthesis.

It's important to note that the information provided is based on the search results, and further research may be required for a comprehensive understanding of protein synthesis in specific contexts.
