Need to know

What you need to know

  • Describe the sequential processes of transcription and translation in protein synthesis.
  • Explain the specific roles of mRNA, tRNA, and ribosomes (containing rRNA) in accurate protein production.
  • Discuss the characteristics of the genetic code and the differences in gene expression between prokaryotes and eukaryotes.
  • Outline the process of post-transcriptional modification in eukaryotes, including the removal of introns and addition of a 5' cap and poly-A tail.
