Curated OER
Scientist Simulation
Students envision the work of a research scientist, and the relationship between molecular biology and medicine. This activity allows students to imagine themselves working as research scientists by asking them to complete the end-steps...
Curated OER
Chromosomes
In this chromosomes worksheet, students complete a crossword puzzle with 33 questions about genetic mutation in chromosomes. They identify traits associated with certain genes.

CONSTRUCTION OF A HEMOGLOBIN GENE
High schoolers use research to see how eight pairs of triplets are equivalent to part of a gene and control a part of heredity. They also understand how red blood corpuscles manufacture normal hemoglobin.

Hhmi: Bio Interactive: Understanding Sequence Assembly
A series of lecture clips helps explain how DNA sequencing is done by using the analogy of shredding multiple copies of a book and then reassembling the text by finding overlapping fragments. The ultimate goal of DNA sequencing is to...

Dna Learning Center: Dna Molecule, Dna Unzip
The DNA double helix contains two sequences of nucleotide code letters than run along the molecule. Untwist the spiral and DNA can be seen as two parallel strands. That's why its sometimes called the double helix. Unzip the strands and...

Biology Wise: Start Codon
A start codon is a nucleotide triplet in a genetic sequence that occurs at the start of a protein's synthesis. Read about how this works and how a mutation can sometimes occur.
