Protein Synthesis

• Transcription

  • RNA polymerase breaks hydrogen bonds between DNA bases
  • RNA nucleotides, which contain uracil instead of thymine, bind to complementary bases on the template strand of DNA
  • RNA polymerase joins adjacent RNA nucleotides through phosphodiester bonds
  • pre-mRNA strand and RNA polymerase detach, resulting in a complete strand of pre-mRNA
  • pre-mRNA is spliced
• process of splicing

  • process in which pre-mRNA is converted to mRNA
  • Involves the removal of introns from pre-mRNA while the remaining exons are attached together
