Flow of Genetic Information Kit © ...where molecules become real TM DNA Replication Activity Guide Engaging in a Discussion of DNA 1. List at least three reasons why a cell must undergo division. ______________________________________________________________________________ ______________________________________________________________________________ 2. Imagine you are cutting a bagel (one of the most common household injuries) and you get a cut. The cut heals. How do the new cells compare to the original (pre-cut) cells?______________________________________________________________________________ 3. How does your body ensure that the new cells are the same?______________________________________________________________________________ 4. How does DNA get into the new cells?______________________________________________________________________________ Teacher Key Deoxyribonucleic Acid (DNA) DNA Replication Teacher Key Page 1 Copyright 3D Molecular Designs All Rights Reserved - 2016 3dmoleculardesigns.com
...where molecules become real TM Flow of Genetic Information Kit © DNA Replication Continued Pair the nucleotides of the template strand to the non-template strand of DNA you constructed, to create a double-stranded DNA model. 5. Record the template strand bases in the blank spaces provided above. 6. Examine the strands of DNA. What do you observe about the arrow ends of the model? ____________________________________________________________________________ 7. What does the arrow indicate? ______________________________________________________________________________ GG C G T A C A C A C T C T A T G T A A C C GG T T C T G T G A C A A T C G A G The arrows are on opposite ends of the strands. Assemble the non-template strand of the DNA sequence according to the pattern shown below. Nitrogenous Bases Modeling DNA Replication Activity In this lesson you will learn how a copy of DNA is replicated for each cell. You will model a 2D representation of DNA replication using the foam nucleotide pieces. The arrow indicates the 3’ hydroxy end of the DNA molecule.
