This DNA Cut and Paste Model Activity is a great activity in which students read a short article about what DNA is and then make their own DNA models by cutting and pasting nucleotide pairs to create their own short sequence. I always complete this activity and then “unzip” the DNA models to make an RNA strand for when we begin to learn about protein synthesis.
-Background Reading page
-Instructions for making a DNA model
-5 analysis questions
-Templates for adenine, thymine, guanine, cytosine, deoxyribose, and phosphate
-Teacher instructions and answer sheet for short analysis questions.

LS1.A: Structure and Function
•All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins
LS3.A: Inheritance of Traits
•Each chromosome consists of a single very long DNA molecule, and each gene on the chromosome is a particular segment of that DNA. The instructions for forming species’ characteristics are carried in DNA. All cells in an organism have the same genetic content, but the genes used (expressed) by the cell may be regulated in different ways. Not all DNA codes for a protein; some segments of DNA are involved in regulatory or structural functions, and some have no as-yet known function. (HS-LS3-1)
