Question

A biological blot where the target for detection is DNA. The method is named after its inventor, the British biologist.

A) Western Blot
B) Southern Blot
C) Northern Blot
D) Eastern Blot

Answer 1

The Southern Blot technique, named after its inventor Sir Edwin Southern, is used to detect the presence of specific DNA sequences in a given DNA sample. The correct option is B.

Step-by-step explanation:

The correct answer is B) Southern Blot.

The Southern Blot technique, named after its inventor Sir Edwin Southern, is used to detect the presence of specific DNA sequences in a given DNA sample.

In this technique, DNA fragments within a sample are separated by agarose gel electrophoresis and then transferred to a thin, positively charged membrane. The DNA fragments that bind to the surface of the membrane are then exposed to a specific single-stranded DNA probe labeled with a radioactive or fluorescent molecular beacon to aid in detection.
