Description
A D.N.A (Deoxyribonucleic Acid) chart (55×90 cm) is a large, full-color educational wall poster showing the structure, composition, and biological significance of DNA. These charts are essential in biology classrooms, labs, NEET prep, and curriculum kits focusing on genetics and molecular biology.
Chart Features and Content
Chart Size and Material: 55 × 90 cm, printed on 80 GSM art or map litho paper, laminated for water and tear resistance—ideal for classroom wall mounting and repeated instruction.
DNA Double Helix Structure: Dominant illustration is a right-handed double helix showing two antiparallel polynucleotide chains twisted around a central axis. Color-coded base pairs (adenine–thymine, guanine–cytosine) are depicted, with hydrogen bonds clearly marked.
Component Labeling: Every chart shows and labels:
Nitrogenous bases (A, T, G, C)
Sugar-phosphate backbone
Base pairing rules (A pairs with T, G with C)
Major and minor groove indications
3' and 5' ends of strands.
Explanatory Insets: Side panels often describe DNA’s role in heredity, gene expression, cell division, and chromosome structure. Some include a brief overview of DNA discovery (Watson, Crick, Franklin).
Visual Highlights: Key concepts such as base pairing, helix pitch (3.4 nm per turn, 0.34 nm between base pairs), and chromosomal packaging in eukaryotes.
Institutional and Catalog Use
Essential for teaching genetic principles, cell biology, and biotechnology. Used for reference during hands-on molecular biology activities (e.g., DNA extraction, PCR simulation, gene mapping).
Available from Flipkart, Etsy, Bright Education, Ubuy, and dedicated science education suppliers—satisfying catalog and curriculum requirements for scientific accuracy, durability, and visibility.
Visual and Digital Standards
Digital versions and compliant images feature vector graphics with clearly distinguished structural elements, suitable for digital catalogs, e-learning, and printable chart libraries.
For the most effective classroom or catalog use, choose up-to-date charts from major publishers, with clear color labeling, function explanations, and scale indicators.
