Study Notes
Transcription and Translation Overview
- Transcription is the process wherein DNA is copied into messenger RNA (mRNA).
- mRNA serves as a single-stranded template derived from a gene in DNA, facilitating protein synthesis.
- A polypeptide chain consists of amino acids linked together, forming the structure of proteins.
Key Components in Protein Synthesis
- Amino acids are the fundamental building blocks that compose proteins.
- Transfer RNA (tRNA) transports specific amino acids to the ribosome for protein assembly.
- An anticodon is a set of three nucleotide bases on tRNA that pairs with a complementary codon on mRNA during translation.
- Codons are triplet bases found on mRNA that correspond to specific amino acids, guiding protein synthesis.
Cellular Machinery
- Ribosomes are the sites where protein synthesis occurs, translating mRNA into polypeptide chains.
- DNA contains the genetic information necessary for the production of mRNA and ultimately proteins.
Cellular Locations
- The nucleus is the cellular compartment where transcription takes place, housing the DNA.
- Cytoplasm is where ribosomes are located and translation of mRNA into proteins occurs.
