Help scientists solve a mixup that has recently occurred in the lab. Someone accidentally compromised the DNA database by removing the labels from the test tubes. Your task is to determine which sample is in which tube. For this, we will use DNA “scissors” (in scientific terms, restriction enzymes) to cut DNA into pieces. Since we know that the “scissors” cut DNA in different places for different samples, we can identify which DNA sample is in each tube by comparing the DNA fragments. Help us restore the DNA database!
