Where does transcription occur?
What is the function of the gene keratin?
What must happen to the DNA molecule for transcription to occur?
What is the difference in bases in RNA?
What is the sequence of the keratin gene? Draw the sequence and the corresponding mRNA
sequence
Where does the mRNA go when transcribed?
Translation:

Where does translation occur?
What is translation?
At what structure is DNA converted to amino acid sequence?
How many subunits does the ribosome have? What are they like?
How many amino acids are there?
How is RNA read at the ribosome?
Why is DNA read in triplet? (i.e. why not in pairs or singles)
Use the genetic code, to give some examples of some codons and the amino acids they code for
Have a look back at your sequence for the gene keratin, use your knowledge of the genetic table to
determine the amino-acid sequence this gene codes for
