Yes

I guess your confused because if you did what i have mentioned you can see that you are extrating the dna not making a model
Read it again youll understand
but if need only a model then i guess you can do the digestive or respiratory system

Extraction of DNA From Plants
things you'll need
test tubes
liquid detergent
contact lens solution
distilated water
salt
vegetables (any)
rubbing alcohol
strainer
Method:
blend any vegetables of any choice with little salt and distilled water till almost blend
now only extract the juice by keeping a strainer under a glass and poring the blend and pressing lightly with a spoon until you only have clear liquid add liquid detergent and stir,leave for two minutes and after that pour it up to 3/4 of the test tube add four drops of contact lens solution , and fill the rest of the test tube with rubbing alcohol leave for a few minutes and you'll see a white layer after 48 hours you can see fully formed DNA
i did this when i was in seventh grade and it will just more than just satisfy your teacher and its also really fun so... all the best
hope this helps you
