HGS DNA and RNA set

These molecular models are easy to assemble, portable, and precisely designed to comply with requirements of various fields of research and education in the life sciences. The A-, B-, and Z-DNA sets are composed of a sufficient number of base pairs of A-T and G-C to construct a double stranded DNA model for one and a half turns of the helix. Support stands are included. Scale: 1 Å = 1 cm.
