The mission of Trinity Christian School is to guide our children in faith, learning, character and leadership by nurturing their relationship with Jesus Christ and educating them for a life of service to God and man.

7th and 8th Graders Study DNA

Evidence of Our Creator God

by Katie Willert


DSC06334What is DNA?  Deoxyribonucleic acid!  It is a chemical code that contains information for an organism’s growth and function.  When it is isolated from a cell and stretched out, it looks like a twisted ladder.  This shape is a double helix.  The sides of the ladder are made of sugar-phosphate molecules.  The rungs are made of chemicals called nitrogen bases.  There are four types of nitrogen bases:  Adenine, Cytosine, Guanine, and Thymine.  Adenine ONLY pairs with thymine.  Cytosine ONLY pairs with guanine.  That is your science review for today!

The 7th and 8th grade students at Trinity School have been learning about DNA in science class.  They had a great time recently making DNA molecules with licorice strips and colored mini-marshmallows.  But, this activity wasn’t all fun and games.  The students were given a sequence of nitrogen bases, and a marshmallow color key (what color stood for what nitrogen base).  They had to construct that sequence on one side of the DNA double helix using the licorice, toothpicks, and the colored marshmallows.  They then had to use their knowledge of base pairs to find the matching base and construct the other side of the DNA strand.  They then labeled all the parts of the DNA.

I wanted to write about this project because the members at Trinity that are taking the “I Don’t Have Enough Faith to be an Atheist” study have learned about DNA as well.  DNA is one of the pieces of evidence that creation scientists use to point to God as creator, as compared to evolution.  I love being able to show my students how science point to our amazing God!  DNA is more complicated than any computer code.  Did you know the DNA code that controls something as “simple” as hair color, if printed out on the computer, would be over 5 pages long?  Did you know that the DNA from ONE HUMAN, if removed and straightened out, would extend for 50 billion kilometers?  That is from planet Earth to beyond the solar system!   Do you think DNA came about by the “accidents” of evolution?  I hope not!  Our DNA is one of the amazing fingerprints by our creator God – always leading us to Himself.   How great is our God!
