Chromosomes & Genes (55x90cm)

A “Chromosomes & Genes” (55×90 cm) educational chart provides visual explanations and labeled diagrams detailing the organization and function of chromosomes and genes for classroom biology instruction.​

Features of the Chromosomes & Genes Chart

Size and Format: The chart is sized at 55×90 cm, printed in color on durable laminated or art paper for easy classroom use.​

Chromosome Structure:

Illustrates eukaryotic chromosomes as condensed, X-shaped bodies made up of tightly wound DNA around histone proteins.​

Major anatomical features are labeled: centromere (joining chromatids), chromatids (arms), telomeres (ends), and p and q arms (short and long arms, respectively).​

Includes diagrams or tables showing the types of chromosomes: metacentric, submetacentric, acrocentric, and telocentric, with differences in centromere position and shape.​

Gene Concept:

Explains that genes are linear segments of DNA located along chromosomes, coding for specific proteins that determine heritable traits.​

Describes gene composition: exons (protein-coding), introns (non-coding), and regulatory regions controlling gene expression.​

May include codon tables and how DNA bases (A, T, G, C) form the genetic code.​

Genetic Inheritance and Variation:

Shows the difference between autosomes and sex chromosomes, how genes are inherited from each parent, and the basics of a karyotype (the complete chromosome set in a human cell).​

Introduces concepts of gene mapping, structural changes (mutations), and their effects on genetic disorders or traits.​

Educational Use:

Diagrams are labeled and color-coded for clarity, often accompanied by concise explanations and example traits or diseases linked to particular chromosomes or genes.​

This chart is designed to visually introduce students to molecular genetics, cell division, genetic inheritance, and the basics of DNA structure and chromosomal function.​
