The DNA replication products visualized during the sanger method of DNA sequencing are observed in which nucleotides are added.
Sanger sequencing is based on the process of DNA replication. A scientist creates a copy of his DNA strand. Then observe which nucleotides have been added. This way you can see the sequence of nucleotides. A laser excites the fluorescent labels in each band and a computer detects the resulting light.
Sanger sequencing produces extension products of various lengths ending in dideoxynucleotides at the 3' ends. Extension products are separated by capillary electrophoresis or CE. Molecules are injected by an electric current into a long glass capillary filled with gel polymer. Selective incorporation of chain-terminating dideoxynucleotides by DNA polymerases during in vitro DNA replication.

Explanation:
with new knowledge , science evolves.
The organelle that provides evidence for this theory is the mitochondria and the chloroplast.
<h3>What is the endosymbiotic theory?</h3>
The endosymbiotic theory is the theory which describes how the eukaryotic cells arose from simple prokaryotic cells.
In the endosymbiotic theory states that when two prokaryotic cells with several abilities came together, one engulfed the other and existed in a symbiotic relationship that enabled the cells to meet their needs for survival an growth.
The mitochondria and the chloroplast provides evidence for the endosymbiotic theory.
In conclusion the endosymbiotic theory describes how eukaryotic cells arose from simple prokaryotic cells.
