Yоu hаve run а Sаnger sequencing reactiоn using a DNA template and a specific primer. The sequencing prоducts are separated on a gel in four lanes, each containing a different dideoxynucleotide (ddA, ddG, ddC, ddT). The lane labeled A shows fragments terminated whenever a dideoxyadenine is incorporated; similarly, the lanes labeled G, C, and T show fragments terminated by their respective dideoxynucleotides.  Question 1. In the Sanger sequencing gel shown (lanes labeled A, G, C, T from left to right), how should the newly synthesized strand be “read” to determine its sequence? [1]   Question 2. Which lane in the gel corresponds to fragments that terminate with dideoxycytosine (ddCTP)? [2]   Question 3:What is the sequence of the strand that was extended from the primer? (Please indicate 5′ and 3′ ends) [3]   Question 4: What is the sequence of the template strand? (Please indicate 5′ and 3′ ends) [4]
