How are copies of dna made
Web29 de out. de 2024 · How many copies of a target DNA molecule are made after 30 cycles of PCR show how you arrive at your answer? After 30 cycles, what began as a single molecule of DNA has been amplified into more than a billion copies (2 30 = 1.02 x 10 9 ). WebDNA sequencing is the process of determining the sequence of nucleotides (As, Ts, Cs, and Gs) in a piece of DNA. In Sanger sequencing, the target DNA is copied many times, making fragments of different lengths. Fluorescent “chain terminator” nucleotides mark the ends of the fragments and allow the sequence to be determined.
