How is alignment length determined by the program
They use ddNTPs and essentially run PCR agai with our DNA samples. The ddNTPs stop the replication at various lengths. These fragments are then aligned from long to short. The ddNTPs at the end of each fragment are then read using a special sensor and an elctropherogram is created.
Habitat fragmentation increases or decreases edge habitat?
increases
