Answer the following questions from the diagram given below:-

The samples in different lanes are from different sources but treated with a common restriction endonuclease. The maximum number of restriction sites are present in

Sample 4

The correct answer is Option (1) → Sample 4

To determine which sample has the maximum number of restriction sites, we need to consider the number of DNA fragments generated after treatment with the restriction endonuclease. A higher number of fragments indicates more restriction sites within the DNA.

If this sample has the highest number of bands (fragments) in its lane, it would have the maximum number of restriction sites. Similarly, the sample with fewer bands would have fewer restriction sites.

So, the correct answer would be the Sample 4 that shows the most number of bands in its lane during gel electrophoresis. The sample with the most fragments (bands) has the maximum number of restriction sites.
