In this activity, students build a paper model of DNA and use their model to explore key structural features of the DNA double helix. This activity can be used to complement the short film The Double Helix. Students use paper nucleotides printed on card stock to build a single-stranded DNA sequence assigned by their instructor.

WebShort Tandem Repeats. Short tandem repeats (STRs), or “microsatellites,” are tracks of tandemly repeated short (1 to 6 bp) DNA sequence motifs. STRs may occur in both intergenic and intragenic regions, including within genes, and account for approximately 3% of the human genome. Some microsatellites are highly mutable and show both sequence ...
