Using your color key, color the diagram to the left to represent your bead model of DNA.

DNA Replication:
Using the shapes/symbols, recreate a picture of
Your DNA model undergoing replication. The diagrams to The right will be your final result.

Nucletoides:

DNA Transcription:
1.
Recolor the diagram to the left to represent your original DNA model. On your diagram label: sugar, phosphate, and individual nitrogen bases (A,T,C, or G).
2.
Draw nitrogen bases as needed to the diagram in the middle to demonstrate how the template strand is used to form RNA. Use the shapes from your DNA model. Label a sugar, a phosphate and each nitrogen base with its letter…(A,G…).
3.
Draw the appropriate nitrogen bases on the diagram to the right to show what the final piece of
RNA would look like if your model had been the original. Label a sugar a phosphate and each nitrogen base with its letter…(A,G…).

DNA Translation:
1.
Recreate/draw your RNA strand using the backbone provided on the left. Be sure to label a sugar, a phosphate and the nitrogen bases.
2.
Circle each codon to show how the nitrogen bases would be grouped.
3.
Draw a tRNA model with the anticodon next to each codon.
4.
Show the amino acid attached to the tRNA.
5.
On the far right, draw the final sequence of amino acids your model produced.
RNA
Sequence tRNA + Anti codon –amino acid Amino Acid
