Final answer:
The chain termination sequencing method, also known as Sanger sequencing, is used to sequence DNA by incorporating dye-labeled dideoxynucleotides. The DNA fragments produced are separated by size using electrophoresis and read on an electropherogram.
Step-by-step explanation:
The method developed by Fred Sanger to sequence DNA is known as the chain termination sequencing, hence the correct option here is (c) Chain termination sequencing. This technique, also referred to as Sanger sequencing, involves the replication of DNA with the incorporation of dye-labeled dideoxynucleotides (ddNTPs) which lack a hydroxyl group (-OH) necessary for forming a phosphodiester bond, causing the extension of the new DNA strand to terminate. These terminated fragments are then separated by electrophoresis according to size and can be visualized on an electropherogram generated by a laser scanner. This process results in a sequence of bands on a gel or a digital readout, which corresponds to the DNA sequence of the original strand being sequenced.
