Study Notes
Protein Synthesis Overview
- DNA serves as the blueprint for protein synthesis, often referred to as the "recipe book for proteins."
- Protein synthesis begins in the nucleus where transcription occurs.
Key Components
- Nucleus: The site of transcription where DNA is converted into mRNA.
- Transcription: The process of copying DNA into messenger RNA (mRNA), which carries genetic instructions.
- mRNA: Messenger RNA that transports genetic information from the nucleus to the ribosome for protein synthesis.
- tRNA (transfer RNA): Molecule that brings specific amino acids to the ribosome, matching them with the mRNA sequence.
Translation Process
- Ribosome: The cellular machinery that reads mRNA sequences and synthesizes proteins.
- Amino Acid: The building blocks of proteins, which are connected in specific sequences to form a protein.
- Codon: A sequence of three nucleotides in mRNA that corresponds to a specific amino acid, facilitating the assembly of proteins.
Final Steps
- Translation: The process taking place in the cytoplasm where the ribosome assembles amino acids into a polypeptide chain, ultimately folding into a functional protein.
