  3. What gases are being exchanged as we inhale?
  4. How do the lungs get rid of all the CO2 they’ve picked up from the blood?
  5. Why do the cells in our body need oxygen? Be specific.

2. Why do we use alcohol?

3. After you add alcohol, what is in the snot-like mass?

4. If this were a lab, what could you do with the material you separated snot-like glob?

PART B 

https://www.youtube.com/watch?v=h3b9ArupXZg USE VIDEO TO ANSWER QUESTIONS 

  1. Explain two structural ways DNA and RNA are different. 
  2. How is base-pairing different in RNA and DNA?
  3. If one nucleotide were transcribed incorrectly or omitted, how would it affect the overall structure of the protein? Create an example sequence of mRNA and proteins (using the codon chart) to demonstrate. 

Let’s practice this process of transcription and translation using a virtual model. Here’s what to do:

  1. Head over to https://learn.genetics.utah.edu/content/basics/txtl/
  2. Complete the tutorial of transcribing and translating a gene
  3. Take a screenshot or photo at the end of transcription and the end of translation.  You will turn these in at the end of the lab.

2nd part of B

  1. Were both pieces of DNA used during transcription? 
  2. How is the mRNA molecule built? 
  3. What happens to the mRNA once it has been completed?
  4. What organelle catalyzes the peptide bonds between amino acids?
  5. How would you describe the sequence of bases on the mRNA compared to those on the tRNA?
  6. What happens to the tRNA molecules after their amino acid that was attached to them has been added to the growing polypeptide?
