Predict: How will the change to the sequence of nucleotides in a DNA segment affect the mRNA transcribed from the DNA?

3. Observe: Place the next two tRNA molecules on the mRNA strand. What happens?

As each tRNA molecule binds to the mRNA, the ribosome joins the amino acid carried by the tRNA to the growing amino acid chain.

4. Describe: UAG (as well as UAA and UGA) is an example of a stop codon. Molecules called release factors bind to stop codons. Place the release factor on the mRNA molecule.

What happens?

Infer: Why do you think stop and start codon signals are necessary for protein synthesis?

1. Explain why when I was adding drops of water to a coin, the coin overflowed at eight drops of water  however, when I added a thin layer of dish soap to the coin, the coin overflowed with water after 10 drops of water. Explain this effect in terms of cohesion hydrogen bonding between like molecules, and surface tension.

2. Explain why when I added drops of water with my finger onto a clean ceramic plate, the drops of water just splashed onto the plate and made no shape. However, when I was adding drops of water with my finger onto a plate with a piece of baking paper on it, the drops of waters landed as a perfect circle with no splashes. Explain  the difference in drop shape in terms of adhesion, the formation of hydrogen bonds between molecules of different types and hydrophobic interactions.
