Questions: 20 | Attempts: 12 | Last updated: Mar 8, 2026

Sample Question 1
What is the main objective of performing the Sanger method in a laboratory?

To determine the exact order of nitrogenous bases in a DNA strand

To create a clone of an organism

To kill bacteria in a sample

To make the DNA double its weight

Sample Question 2
In the process of sanger sequencing, what special "terminator" molecule is used to stop DNA growth?

Dideoxynucleotide (ddNTP)

Deoxynucleotide (dNTP)

Amino Acid

Glucose

Ribose Sugar

Sample Question 3
During sanger sequencing, the DNA polymerase stops building a strand every time it accidentally incorporates a ddNTP.

True

False
