Product Code : EL-PL-13565
Jlab Export is a leading DNA Double Helix Model, 22 Segments Manufacturer,and suppliers in India
DNA Double Helix Model, 22 Segments (code EL-PL-13565) is a molecular model set for building a right-rotating DNA double helix from colour-coded parts: the four nitrogen bases, the deoxyribose sugar and the phosphate groups. The set weighs 0.5 kg, measures 44 x 11 x 11 cm and can also be used to show complementary base pairing and DNA replication. It is made by JLab in Ambala, India.

How the Parts Fit Together
Each nucleotide is built from one base, one deoxyribose and one phosphate group, which is why the set has 44 of each backbone part. Adenine (blue) always pairs with thymine (orange) and guanine (green) with cytosine (yellow), so the 11 of each base make 22 base pairs. The phosphates and sugars link into the two outer strands, and the pairs between them twist to the right, as in the DNA of living cells.
Showing Replication
Separating the two strands down the middle, pair by pair, shows how the helix unzips. Each freed strand then acts as a template, and students place the complementary base opposite every exposed one, which is how DNA is copied.
