DNA runs from the cathode (-ve electrode) the the anode (+ve electrode) because DNA is negativly charged. This charge exists because of the phosphate backbone of DNA.

What is the negative electrode of a voltaic cell called?
This is the anode.
How do you interpret electrophoresis?
In electrophoresis, DNA is subjected to an electric field which causes the genetic material to migrate in a direction from a cathode to an anode. The DNA that is closest to the anode is determined to be shorter in length compared to the DNA that is closer to the anode. This is explained by fact that the smaller fragments of DNA are better able to travel through the porous gel.
What is the half cell reaction of ordinary dry cell?
An ordinary dry cell is pretty well answered by: Anode: Zn → Zn2+ + 2e- Cathode: 2NH4+ + 2MnO2 + 2e- → Mn2O3 + H2O + 2NH3
Where does reduction occur in an electrolytic cell?
The electrode where reduction occurs
What are threadlike structures that control the traits of organisms?
They are the chromosomes.Each chromosome of a eukaryote consists of one molecule (or, after DNA replication, two molecules) of DNA, running from end to end of the chromosome, plus many protein molecules around which the DNA is coiled. It is the DNA that is the genetic material, which determines whether the organism becomes a rhinoceros or rhubarb.
Cations are attracted to cathod or anode?
DNA is neither cathode or anode, but it is negatively charged, so the DNA molecules will rn from anode to cathode
Why does the DNA fragment size change as you move from the cathode to the anode?
The DNA fragment size decreases as it moves from the cathode to the anode. This is due to the negative charge of the DNA moving against the positive charge of the cathode.
What is cathode and anode?
cathode is electron negative but anode is positiveAnswerFor electrochemical cells, electrons travel through the external circuit from the anode to the cathode.
Is iron a anode or cathode?
it is an anode
The relationship between a cathode and an anode involves what?
The relationship between a cathode and an anode involves
On a silicon-controlled rectifier which wire is the anode and which the cathode?
Anode is positive, cathode is negative
That is function anode and cathode piping?
that is function of anode and cathode in underground piping yes
What is the anode and cathode of Baghdad's battery?
the copper cylinder(cathode) and iron rod(anode)
What is the negative electrode of a voltaic cell called?
This is the anode.
IS carbon rod a cathode or anode?
cathode
In cathode ray tube cathode and anode rays travel opposite to each other but they are not neutralized. why?
There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.
