After a long day, you arrive home and are surprised to find no one there. When you go to the biology lab, you find a note and decide to read it...

Look at the note on the fridge

Greetings, There has been a devastating mutation in the DNA strands of everybody in Texas, and we need you to make a new sequence.

solution

Elongation: tRNA molecules match codons and anticodons, length of strand increases

Initiation: rRNA interacts with mRNA strand at first start codon

Termination: stop codon reached, process ends
