First on Friday, we were assigned new lab groups. Then we used a model kit to build DNA! We had a bunch of colored tubes which represented nucleotides. Yellow represented guanine, orange showed adenine, blue was cytosine, and green was thymine. There were black pentagons that represented deoxyribose, white tubes that represented phosphate, and white rods that represented hydrogen bonds.

After we constructed our DNA, we had to demonstrate how DNA replication occurs. We began by unzipping the DNA. Then new nucleotides were added to the two strands. After DNA replication, we were left with two identical strands of DNA.

DNA "unzipping" before replication
