Within the context of gel electrophoresis results displaying distinct bands for DNA samples collected from organisms A, B, C, and D, identify the precise nature or distinguishing attribute of band X. Additionally, elucidate how the presence or properties of band X in the gel electrophoresis results offer valuable insights into the DNA samples derived from organisms A, B, C, and D, surpassing those provided by the remaining bands.

Option: 1

The largest DNA segment that moved slowly

 


Option: 2

Smaller fragments of DNA will pass through the gel matrix's pores more quickly and extensively than bigger ones. 


Option: 3

The largest and fastest-moving DNA fragment


Option: 4

Smaller DNA fragments will move through the gel matrix's pores more quickly and farther than larger ones.

The dynamic behavior within the gel matrix pores dictates that smaller DNA fragments will swiftly and efficiently traverse greater distances compared to their larger counterparts.

As observed in the gel electrophoresis results, Band X, positioned closest to the bottom of the gel, provides a significant clue about its nature - being the smallest fragment, it signifies the swiftest migration.Hence, the correct answer is option 4.
