1. TRANSCRIPTION DNA – RNA – Protein

2. Types of RNA  Messenger RNA (mRNA) - is a copy of a portion of the original DNA strand  carries the RNA copy of the DNA code for one or more genes in a series of codons; one codon codes for one amino acid  Ribosomal RNA (rRNA) - made of 2 subunits  work together to make ribosome that is capable of reading mRNA from 5’ to 3’ and assembling amino acids to make protein  Transfer RNA (tRNA) - capable of attaching to an amino acid at top near the acceptor stem; at bottom has anticodon loop that is the compliment of the codon found on mRNA

3. 3 Steps  Initiation  Elongation  Termination

4. Initiation

5. Elongation

6. Termination

7. Eukaryotes  mRNA released in pre-mRNA  must undergo changes before being released from nucleus  Cap and Tail  Splicing

8. Cap and Tail

9. Splicing

10. Reverse transcription???
