2.4.1 Theoretical Questions

The exam next week will consist on a programming test, and a (random) theoretical question from the set below. Use the class time to review the former lectures and make sure you are able to answer all of them.

1 Basic Questions:

1. What are the nucleotides that compose DNA? What are the nucleotide pairs able to bond within the DNA?
2. What are the nucleotides that compose RNA? How are nucleotides in a DNA strand translated into RNA?
3. What is an open reading frame in a DNA strand? How can we identify them?
4. What are codons? Given a codon, how can we know which aminoacid it will become?
5. What is a gene? What is the full process transforming it into proteins?

2 Operational questions

All operational questions will start with a DNA nucleotide sequence. You will have to:

1. Write the complementary DNA strand.
2. Translate the original DNA sequence into the complementary RNA.
3. Find an open reading frame in the RNA sequence. Tip: it will have 9 nucleotides.
4. Translate it into codons using the table below.
