					                     DNA replication, transcription and translation

1) First start off by coloring another sheet with the correct color codes and cut these out.
You will build you DNA.
2) Now make a double stranded DNA molecule that is at least 15 base pairs long using
your cutouts. Include all the parts to DNA. Begin with TAC and end with ATC.

Write out your DNA strand below:

Write out the complementary DNA strand:


3) Before you move on, get this checked by Ms. Estrada.
4) Using the DNA strand, make a mRNA molecule from the DNA strand starting with
TAC.

 DNA:
mRNA:

4) Get with a partner and make a DNA molecule that is at least 30 base pairs long using
your cutouts. Include all the parts to DNA. Begin with TAC and end with ATC.
Write out:

 DNA:
cDNA:
mRNA:


5) Before you move on, get this checked by Ms. Estrada.
6) Describe the process of transcription using words. Make sure you include everything
that happens!




7) Describe this process out loud to a person in another group. Have them write down
below notes of things you included.
8) Now we have the mRNA. Let’s find out what codons you have. Below, list all the
codons along with the amino acid that they code for. An example is provided to help you
with this. Ex. CUG-Leucine)




9) What is the order of amino acids that have been coded for to make your protein?




10) Describe this process of translation. What are the specific steps that need to happen?




After activity questions:
11) What are some differences between RNA and DNA, and RNA transcription and
DNA replication?




12) Why is mRNA necessary in the process of making proteins?




13) You have discovered a protein that is made up of 14 amino acids. How many
nucleotides from a coding strand of DNA is needed? Explain how you came up with this.




14) Where in the cell is the process of transcription happening? Translation?
