DNA Double Helix Model

Nice model. Have a fun time putting it together with my kid. Require careful attention with the instruction to put it together correctly the first time, but it is no big deal if a mistake is made since action is not permanent. The backbones can be slippery if you need to remove the A, T, G, C nucleotides from the backbone. I spent good 10 minutes looking for one of the backbone after it flew away from my fingers when I was trying to correct my mistake. The three iron bars are a bit difficult to put into the two bases, but it is not a show stopper. Once you get them into the two bases, it forms a strong connection. I guess you can't really have it both ways.

This product is very Hands-On educational and easily constructed easy to deconstruct and help people consider the possibility of in the terms of epigenetics can we essentially rewrite parts of our DNA by lifestyle behavior and choices

Got this for my son for biology, would have given 5 stars, but it falls apart far too easily after assembly

I love this DNA model so much! I brought them to my office to display.

Unable to use product. The base pairs connected to each other fine, but the sugar/phosphate backbone pieces did not connect tightly to the bases at all. The structure kept falling apart before even a quarter of the way built.

This was so easy to put together but putting the stickers on the parts took me over an hour. They are about the size of a BB. Even with tweezers it was crazy difficult. This is not for kids unless an adult does the stickers

Pieces are so cheap and were breaking and it is very difficult to put together.

This is hard to put together but it makes a nice addition to my office.
