BactoBeads™ are non-pathogenic, freeze-dried microbes (bacteria and lower eukaryotes) that are easily cultured for use in the classroom. Each bead contains microorganisms, buffer, salts and nutrient broth in an instantly soluble pellet.
Exploring Chromosomal DNA
The nucleus is a dense organelle that contains the genetic material of a cell. How dense? The human genome is around 3 billion nucleotides and the average length of a nucleotide is 0.6 nanometers, so stretched out the DNA in a cell would be around 1.8 meters or 5 ft. (Here’s the math: 3.0 × 109 x 6.0 × 10-10 meters = 1.8 meters).

DNA Barcoding: Identifying Organisms at the Molecular Level
How would you identify all the species in the picture? You could consult a field guide, ask a mycologist (a person who specializes in fungi), or you could sequence its DNA. This last choice is becoming increasingly popular and is known as DNA barcoding. DNA barcoding uses short polymorphic segments of DNA to classify an organism as belonging to a particular species.

Biotechnology Basics - What is a Model Organism?
A model organism is any plant, animal or microorganism that allows us to study fundamental questions in biology that may be hard to study directly in complex organisms like humans.

Linking Biotechnology to Physical Science & Engineering Standards
In brief, the Next Generation Science Standards are a set of guidelines that focus on preparing students for careers in STEM fields including biotechnology, engineering and technology. These new set of standards were set in place to help teachers explore the fundamental concepts important to STEM fields – Life Science, Physical Science, and Engineering and Design.
