Which electrode do DNA fragments migrate toward?
468872
DNA is composed predominantly of a phospho-ribose sugar backbone.  Due to the high phosphate content (which is negatively charged), the DNA molecule has an overall negative charged and migrates towards the positive electrode in a gel system (such as agarose or polyacrylamide).  \n\nThe positive electrode is referred to as the "anode" and is commonly the Red electrode in these systems - DNA "runs to Red".

.....They showed that alternating deoxyribose and phosphate molecules form the twiested uprights of the DNA ladder.  The rungs of the ladder are formed by complementary pairs of nitrogen bases--A always paired with T and G always paired with C. \n\nThis is the site I got it from\nwww.dnaftb.org \n\nI hope it helps!

The scientific supply companies like VWR probably have them.\n\nI searched for "oxygen reduction potential electrode" and got a bunch of hits.  Try that.\n\nYou'll also need a meter to attach it to.  Many better pH meters can handle this kind of probe as well.

Here's a great animation that helps explain it:  http://www.johnkyrk.com/DNAreplication.html

I am only positive on question 4, the okazaki fragments as you probably know are the fragments that are made when replicating DNA away from the replication fork, the DNA strand is replicated by DNA Polymerase, which is one part, and since the DNA is anti-parallel and you must add on to the 3 prime end the DNA strand has to be flipped over the Polymerase, to keep the strand going in an orderly fashion.  The reason it is necessary is because DNA polymerase builds in one direction and since DNA is anti-parallel, one must be made in another way to accommodate for this.

The electrode part doesn't matter. All you need is a strip of copper wire and a strip of zinc. These are easily found at a hardware store.

1. Gene transformation\n2. Junk DNA\n3. Major Histocompatibility Complex - MHC\n4. X-linked\n\nBy the way okazaki fragments are bits of DNA formed during the replication process.

One really easy answer is DNA sequencing. Nanotechnology deals with objects measured in the billionths of a meter. Most say objects less than 100 nanometers. Therefore, although the length of a DNA Strand is way to long to be considered Nanotechnology the individual base pairs fit into nanotechnology perfectly.

Consider a regular climbing ladder.  If the ladder was sawed in half by sawing each rung crosscut thru the middle than each half of the ladder would represent one  DNA strand.  Each new organism receives a single strand from each of it's parents.  The two strands join to make the new organism's double stranded DNA.  The rail or sides of the ladder would represent the sugar and phosphate link backbone of the DNA.  The sawed rung would represent the nucleic acid bases.  The bases are classified as either purines or pyrimidines.  The two purines are Adenine (A) and Guanine (G) which are similiar to the compound Purine.  The two pyrimidine bases are Thymine (T) and Cytosine (C) which are structured similiar to the compound Pyrimidine.  In RNA Thymidine is replaced by Uracil.  The collective term for these structures is "nitrogenous base".  Each base contains either/or hydrogen (h), nitrogen (n) and oxygen (o) atoms located on the structure where the "cut" would exhist on the sawed ladder rungs.  When these bases move close together there is an attraction between these atoms and a bridge forms called a hydrogen bond  or h-bond.Thymine has an o and a h.  Adenine has a h which is attracted to T's o and an n which is attracted to T' h. A and T always h-bond or pair.  Cytosine has an h,n,and o.  Guanine has two h's and an o.  one h on guanine is attracted to the o on cytosine, the other to the n.  The o is attracted to the h on cytosine.  Therefore C always pairs with G and is held together by three h-bonds, where A and T are paired by two h-bonds.  In total the h-bonds strongly bind the two DNA single strands together but one at a time they can be broken to seperate the strands much like a zipper opening link by link.  Since C always pairs with G their proportion is is always the same.  The same is true for A and T.  Each Dna single strand has what is called a 3' (three prime hydroxyl) and a 5' (five prime phosphate) end.  When the two single strands pair to form thd Double strand they Form with the 3' end of one strand joining at the 5' end of the other strand.  This is known as antiparallel since they are running in opposite directions.

Inside are two electrodes.  One is made of Zinc, and the other is made of Manganese Oxide.  These make up the positive and negative terminals respectively.  The electrodes are surrounded by an alkaline electrolyte

do you mean interactions BETWEEN nucleic acids and proteins?  If so there's a lot of ways you can study that - you can do a footprint analysis - digest the nucleic acid in the presence of the protein and see what piece gets protected to see where the protein binds if you know the identity of the two interacting molecules.  If you don't know their identity you can try a gel-shift assay where DNA will move at different rates on a gel in the presence and absence of various proteins.  If you know the protein but not the DNA you can try an affinity column with the protein immobilized and then try to determine which DNA sequences bind.  You can also try to determine the crystal structure of a co-crystal if you have a lot of the two materials.  good luck!

I think you can find everythin u are lookin for and more on this site.. good luck!!!http://www.tannerm.com/electrochem.htm

If you are in Europe try Novozime (Netherland)\nIf you are in USA try Genencor \n\nTelomerase is an enzyme that take part in replication mechanism, especial in cancer cells (they do not lose a part of its DNA when the two strands are copied)

use a potato and two different metals as electrodes. The link will help you, do your own homework, or web searching atleast! it was the second link in google for g** sake!
