Lab: DNA Gel Electrophoresis (Part 2) Instructions: The above image is of a completed DNA gel containing the fragmented DNA of the breast cancer causing gene, HER-2, and the sample(s) of 5 patients being screened for said oncogene. Answer the following questions completelv and to the best of vour ability and attach with your respective lab report. 4. Identify the specific lane/well of the gel loaded with the DNA standard/ladder. 5. Lane 6 holds the gene of particular interest (i.e. HER-2) this is the gene you are trying to detect. Lanes 1-5 are the DNA samples of the patients being screened for the tested oncogene. Identify the patient or patients that is/are positive for the expression of said gene 6. Approximate the size of each fragment of DNA within the positive patient(s)' sample ONLY.Explanation / Answer
4 Lane seven from left side is the DNA standard/lladder
5 Lane third patient is positive or the expression of that gene
6 Approximately the DNA fragment having 20000 base pairs
