a collection of dna fragments of various lengths was subjected to electrophoresis. arrange these dna molecules in order, based on the distance they would travel from the well. the molecule that travels the shortest distance should be at the top of the list, and the molecule that travels the greatest distance should be at the bottom of the list.
a. 900 bp
b. 2500 bp
c. 4200 bp
d. 6000 bp
e. 8000 bp

Answers

Answer 1

DNA fragments spanning varying lengths were separated using electrophoresis. Depending on how far they would go from the well, their pressures would be 8000 bp, 6000 bp, 4200 bp, 2500 bp, and 900 bp.

How does DNA function? What is it?

The instructions required for a creature to grow, endure, and reproduce are encoded in its DNA. Dna fragments must be transformed into information that may be used to build proteins, that are molecules, in order to perform these functions.

Where in the body can you find DNA?

Nearly every of the body's cells contains the same DNA. Although some DNA can also be found in the mitochondria, the majority of DNA is found inside structures called chromosomes. The DNA in chromosomes is wound around transcription factors (alkaline proteins).

The series of electron flow in the respiratory chain in the mitochondria membrane is-

NADH -------> Q --------> Cyt b ------> Cyt c1 --------> Cyt c -------> Cyt (a + a3) -------> O2

Complex I ; NADH dehydrogenase Complex Facilitated the electron transfer NADH to ubiquinone

Complex II; Succinate dehydrogenase Complex Facilitated the electron transfer succinate to ubiquinone

Complex III; Cytochrome bc1 complex or Ubiquinone: cytochrome c oxidoreductase Facilitated the electron transfer from ubiquinol to cytochrome c.

Complex VI; Cytochrome oxidase Facilitated the electron transfer from cytochrome c to O2​​​​​​.

In the electron transport chain, four protein complexes (designated complex I-IV) are involved in transporting electrons from NADH and FADH2 to molecular oxygen.

Complex I creates the hydrogen ion gradient by pumping four hydrogen ions from the matrix into the intermembranous region across the membrane.
