Ms.
Czerwinski and her Freshmen Life Science classes recently built
models of the DNA molecule in order to understand its structure
and function better. A specific DNA sequence was modeled
with different beads for the bases, sugar, and phosphate groups
that compose the DNA molecule. The students chose their
own colors and used wire to form the double helix DNA molecule
which they mounted on a permanent wooden base.
"It took a couple of
class periods to get done especially when we had to count the
beads to be sure the backbone of the DNA model was correct. The
beads and the bases were color coded to represent different elements
which make up DNA", says student Julia Seksenski.
This hands-on activity gave the students a better
grasp of the DNA structure which will allow them to understand
how DNA provides the instructions for making various molecules.
