<p>This is a remix of my DNA / RNA manipulative set, which can be found here <a href="https://www.thingiverse.com/thing:1259352">http://www.thingiverse.com/thing:1259352</a></p> <p>A video overview can be found here, <a href="https://youtu.be/eVgUMtTA06c">https://youtu.be/eVgUMtTA06c</a></p> <p>Lesson Plans and lab work is now available on my teacher pay teacher site, <a href="https://www.teacherspayteachers.com/Product/3D-Printable-DNA-RNA-Manipulative-Lab-1-3452084">https://www.teacherspayteachers.com/Product/3D-Printable-DNA-RNA-Manipulative-Lab-1-3452084</a></p> <p>When I presented the original version to my biology class, students asked if there was a way to display or string the pieces together to stabilize them. We thought more about it, and I realized that these could be be strung together like a necklaces. They could also be displayed for science fairs and presentations.</p> <p>So I remixed the set to include 3 mm holes through all the pieces so you can thread floss through them.</p> <p>You can print these pieces in different colors like I did in the DNA / RNA set, I just prototype them in lime green.<br/> If you want to help students see how A, T and C, G pair together, print the tiles in two different contrasting colors. This way they can see how each pair together.</p> <p>If you want to display these on the whiteboard, use flexible magnetic tape to stick these on the whiteboard.</p> <p>REVISIONS FOR V2 Files</p> <p>Dis D V2 12.stl: The shape was changed to prevent students from fitting the prior D piece together with the A in the wrong location.</p> <p>Dis 35 V2.stl: The 3 prime and 5 prime pieces have been reshaped.</p> <p>Dis A V2 6.stl: The A piece is now the larger one to better match the chemical size. The A lettering has been moved to make room for the holes for the string.</p> <p>Dis T V2 6.stl &amp; Dis U V2.stl: Both have been corrected to be smaller then A.</p> <p>Dis G V2 6.stl: The odd offset has been corrected, and letter moved.</p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>LulzBot</p> <p><strong>Printer:</strong></p> <p>TAZ 5</p> <p><strong>Rafts:</strong></p> <p>No</p> <p><strong>Supports:</strong></p> <p>No</p> <p><strong>Resolution:</strong></p> <p>02-0.3 mm</p> <p><strong>Infill:</strong></p> <p>5%</p> <p><strong>Notes:</strong></p> <p>Print A, T, C, G different colors.rnPrint R,U the same color.rnPrint P, D in the color you have the most ofrnthe 3 - 5 prime holding block should be printed in a neutral color. For visual cues, make a color key for your students. rnrnFor a better color contrast and visual aid, print the pieces in two colors.rnrnPrint A with color 1, switch to color 2. Then on the next batch print T starting with color 2, then switch to color 1. Do the same procedure for C &amp; G, D &amp; P to create a clear color matching scheme.</p> <h3> Post-Printing</h3> <p>Break all sharp edges, use a 3 mm hand drill to clean out any clogged holes.</p> <h3> How I Designed This</h3> <p><strong>DNA / RNA manipulative remix</strong></p> <p>This was designed from the original files in TinkerCAD.I put 2 3 mm holes though the pieces to provide a way to string them all together. rnrn</p> <h3> Custom Section</h3> <p><strong>Project: Display DNA / RNA sequence</strong></p> <p>For this project, I wanted a way to display a students DNA / RNA sequence for science fairs or presentations. rnrnBy putting holes through the pieces, students can string them together for a science fair project or presentation.rnrn</p> <p><strong>Objectives</strong></p> <p>Students demonstrate their understanding of DNA, RNA, and genetics.rnStudents produce a model to demonstrate scientific knowledge for public presentation. rnStudents presents a professional presentation for a varied audience. rnStudents presents genetic research to a professional audience. rn</p> <p><strong>Audiences</strong></p> <p>High School biology, AP bio, College biology, College genetics, genetic councilors and medical professionals.</p> <p><strong>Preparation</strong></p> <p>Students should understand DNA/ RNA, and genetics.rnStudents should prepare their research, and plan out how to model it with this set. rnStudents should 3Dprint enough base pairs to meet their display needs.</p> <p><strong>Steps</strong></p> <p>This set can be used as a display piece for genetic research. rnAfter conducting your research, use this set to produce a physical model for presentations. rnrnUse this set to demonstrate restriction enzymes, cleavage sites, and DNA sequences involved in research.</p> <p><strong>Results</strong></p> <p>As a result of this, you should have a product you can take to professional conferences and science presentations.rnrnThe public can inspect your work and model to see the DNA sequence you are working with.</p> Category: Biology
