1. Arrange the following molecules from least to most specific with respect to the original nucleotide sequence: RNA, DNA, Amino Acid, Protein
Protein, amino acid, RNA, DNA

2. Identify two structural differences between DNA and RNA.
Two structural differences between DNA and RNA would be that RNA contains ribose while DNA is missing the hydroxyl group form its ribose. Also, RNA is created by transcription of a gene locate in the cells of DNA. DNA is doubled stranded whereas RNA is single stranded.
3. Suppose you are performing an experiment in which you must use heat to denature a double helix and create two single stranded pieces. Based on what you know about nucleotide bonding, do you think

Her original drawings are valuable and informative. She will not provide the original copy to everyone involved in constructing the building. Instead, she gives the electrician a copy with the information she needs to build the electrical system. She will do the same for the plumbers, the framers, the roofers and everyone else who needs to play a role to build the structure. These are subsets of the information contained in the original copy. Your cell does the same thing. The “original drawings” are contained in your DNA which is securely stored in the nucleus.

1. Use a pen or pencil to write a five word sentence using no more than eight different letters in the space below.
2. Now, use the red, blue, green, and yellow beads to form “codons” (three beads) for each letter in your sentence. Then, create codons to represent the “start, “space” and stop” regions within your sentence. Write the sentence using the beads in the space below:
3. How many beads did you use?
4. Assign one Pop-It® bead to represent each codon. You do not need to assign a Pop-It® bead for the start, stop and space regions. These will be your amino acids.
5. Connect the Pop-It® beads to build the chain of amino acids that code for your sentence (leave out the start, stop, and space regions).
6. How many different amino acids did you use?
7. How many total amino acids did you use?
