A DNA model that scientifically faithfully reproduces the helical structure etc. in the Lego block

The DNA model to be sold in general isTo close to 100,000 yenThere were things, so it was hard to get it, so we made the DNA model using LEGO. Even though it is made by LEGO, it sticks to scientific correctness, expresses bases by using blocks of various colors and shapes, and the helical structure faithfully reproduces the twisting method and the height to width ratio.

In the sense that it is a Lego block DNA model from Japan, the stage of the movie is a tea room.


Spin the DNA model by turning the teacup.


The model is a right-handed helical structure that rotates once in 10 steps.


Width 2 nm: Created based on the ratio of height (10 steps) 3.4 nm.


Main grooves and minor grooves which are features of double helical structure are also reproduced.


The orientation of sugar in both strands is arranged in the opposite direction.


The bases (ATGC) are color-coded, respectively, and purine bases are made larger than pyrimidine bases.


Also, adenine is a structure that binds thymine and guanine binds cytosine perfectly.


I will stick like this.


Below are examples of failure.


Grab the Lego block at the top ... ...


If you pull it to the left and right, the two chains unravel.


It's like this when you are unwound.


Furthermore, it is also possible to remove each chain.


I will put together the two chains I removed again.


Twisting around, it is completed by joining the blocks together at the top.


The DNA model made by Lego block was made by Rikkyo University staff and students, and loans are also made for university lessons.


Moreover, although general sales are not done so far so far,LEGO® CUUSOOIt will be an official product of LEGO when the click on 10,000 is reached, so we are currently recruiting supporters.
