Fun with DNA
Last week we continued our exploration of evolution at the microscopic level. We examined the structure of DNA and how it replicates and expresses itself through proteins by actually building a model of this amazing molecule using red vines and marshmallows. Check out the following pictures and videos to get a sense of how DNA is able to use its double helix to compact itself.

very cool idea. Girls carry their kid's future dna (1/2 of the chromosomes anyway) from birth to the end of their child rearing years. Their behavior choices (i.e. drugs and alcohol and chemicals ) can affect the maternal half of the chromosomes that might end making a baby. So protect your half of the licorice and marshmallows ladies!!! (I'm sure you already learned this but I love to mouth off ;-) kim
Respect the marshmallows...
