• What does transcription make??

  Different products in eukaryotes and prokaryotes
• What are both copied into mRNA during transcription in EUKARYOTES?

  introns and exons
• What is pre-mRNA?

  mRNA strands containing introns and exons are called pre-mRNA
• What happens after pre-mRNA is formed in eukaryotes?

  Splicing occurs
• What is splicing?

  Introns are removed and the exons joined together- forming mRNA strands.
• Where does splicing occur?

  Nucleus
• What happens after splicing has occurred?

  The mRNA then leaves the nucleus for the next stage of protein synthesis (translation)
• What is produced in prokaryotes?

  mRNA is produced DIRECTLY from the DNA- without splicing taking place
• why is there no need for splicing in prokaryotes?

  Because there are no introns in prokaryotic DNA
• What is protein synthesis aka?

  Peptide synthesis
