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.
