Product Description

Artificial DNA Model on Stand – Biology & Genetics Teaching Aid

The Artificial DNA Model on Stand is a precision molecular teaching tool designed to demonstrate the fundamental B-DNA double-helix structure discovered by James Watson and Francis Crick. Manufactured from durable, high-density ABS polymer and mounted on an upright support stand, this 3D model presents the spatial organization of antiparallel polynucleotide strands. It serves as an essential teaching benchmark across biology classrooms, biotechnology departments, medical colleges, and research seminars throughout Bangladesh.

Visualizing molecular genetics concepts—such as complementary base pairing, major and minor helical grooves, and hydrogen bonding—often presents a major cognitive barrier when relying solely on 2D textbook sketches. This physical DNA model bridges that gap by physically illustrating the structural stoichiometry of DNA. Each nitrogenous base is distinctly color-coded and keyed with specific physical connectors representing purine-pyrimidine complementarity: Adenine (A) pairs strictly with Thymine (T) via double bonds, and Guanine (G) joins Cytosine (C) via triple bonds.

The central spiral spine accurately demonstrates a complete 360-degree helical turn, showcasing pitch height and the alternating sugar-phosphate backbone. Mounted on a heavy-duty acrylic or polymer base with a central vertical metal support rod, the assembly can be rotated smoothly during classroom lectures or detached for hands-on student assembly practicals. Victor Scientific Co. supplies high-grade scientific teaching models and genetics laboratory equipment with guaranteed quality and swift nationwide delivery across Bangladesh.

✹ Key Features

Watson-Crick Double Helix Geometry

Accurately replicates the B-DNA configuration, showing right-handed coiling, antiparallel strand orientation, and distinct major and minor grooves.

Color-Coded Nitrogenous Base Pairing

Features distinct, bright colors for Adenine (A), Thymine (T), Guanine (G), and Cytosine (C) to reinforce strict complementary base-pair rules.

Tactile Hydrogen Bond Demonstration

Base pairs interlock using precision pin-and-socket joints representing specific hydrogen bond connections (2 bonds for A-T and 3 bonds for G-C).

Durable ABS Plastic Construction

Fabricated from non-toxic, impact-resistant ABS and PVC plastic that resists fading, chipping, and degradation in humid laboratory environments.

Rotatable Upright Display Stand

Supported by a stable weighted base and a central stainless steel or coated aluminum support rod that allows 360-degree manual rotation for viewing.

Modular Dissectible Design

Individual nucleotide components, base rungs, and phosphate-sugar links can be disassembled and reassembled during active student laboratory practicals.

✹ Applications

- High school (SSC) and higher secondary (HSC) biology and genetics classrooms

- University undergraduate departments of Biochemistry, Biotechnology, and Microbiology

- Medical college basic science and molecular pathology lecture halls

- Nursing and allied health institute genetics foundation courses

- STEM science exhibitions, Olympiad training, and interactive learning displays

- Agricultural universities and seed breeding technology demonstration centers

✹ Why Choose Artificial DNA Model on Stand?

- Converts abstract sub-microscopic molecular genetics into a tangible, physical learning experience.

- Color-coded components provide instant visibility across large lecture halls and laboratories.

Frequently Asked Questions (FAQ)

Q1

What is the price of the Artificial DNA Model on Stand in Bangladesh?

A1

The price of an Artificial DNA Model on Stand in Bangladesh typically ranges between BDT 1,200 and BDT 3,500, depending on model height (compact 45cm models vs. large 60cm lecture models), component modularity, and base material. Contact Victor Scientific Co. directly for exact quotes and school tender discounts.

Q2

Can the DNA model be disassembled by students during practical classes?

A2

Yes, the modular nucleotide and base pair pieces can be easily detached and reassembled on the central rod, allowing students to physically practice DNA base-pairing and sequence modeling.

Q3

Does the model accurately show complementary base pairing?

A3

Yes, the model strictly follows Watson-Crick pairing rules using distinct color markers and connection teeth so that Adenine only joins with Thymine, and Guanine only pairs with Cytosine.

Q4

What are the dimensions of this DNA teaching model?

A4

The standard educational model stands approximately 45 cm to 60 cm in height with a base diameter of 12 cm to 15 cm, making it ideal for classroom teacher desks and laboratory demonstration tables.

Q5

Does Victor Scientific Co. deliver biology models outside Dhaka?

A5

Yes, Victor Scientific Co. safely packages and delivers scientific models to all 64 districts across Bangladesh—including Chattogram, Rajshahi, Khulna, Sylhet, and Mymensingh—via trusted courier services within 24 to 48 hours.
