Accuracy or fidelity of replication doesnt depend on DNA bases, the fidelity or keeping the DNA as correct is accompanied by DNA polymerase enzyme!
so that there will be two sets of DNA ... one for each new cell. If the DNA doesnt replicate one new cell would have no DNA. and cells need DNA.
PEllet is freezed approximately at 4 degree celsius this is done because the enzymes remain inactive at this temperature and is activated only when needed so that it doesnt degrade the solution containing DNA.
technicly yes, and it may affect the action of the telemorase, but don't forget, even if a mutation doesnt do anything, that doesnt mean it isn't a mutation. most mutations are silent (have no effect).
Deoxyribose is more stable! If you look at the structure of ribose in RNA you see that it has OH Groups at C2 and C3, both of which are reactive. We need the one at C3 to react with the next phosphate, but C2 can only lead to crosslinking; damaging the structure. If this happens to RNA its not a big deal for we can always produce another strand. If its DNA its a serious mutation, so cells have to use deoxyribose for DNA for it doesnt have a free OH at C2. Deoxyribose is produced from ribose. Using deoxyribose for RNA is an unnecessary waste of energy; the crosslinking doesnt happen that often anyway.

dna is copied
DNA is named DNA because it is de-oxy ribo nucleic acid. In contrast to RNA, DNA doesnt have 2'-oxygen in the ribose sugar hence it is stable than RNA. Chemically DNA is the same for any genes that code for different proteins.
science doesnt lie it just states the facts.
Yes it does. The question is how different (or how similar)?

RTWP and this will work in 2009. that doesnt work and its already 09
This toy doesnt have one. I own 3 of them for my child. I just checked right now.
The nucleus of a plant cell stores genetic information in the form of DNA. DNA contains instructions for the development, growth, and functioning of the plant cell.
Yes it is. (Person who asked): Dangit! The DNA Strands are so dumb because it doesnt even represent or even SHOULD represent a powerful beam.
It doesnt form anything. What it does is increase your chance of getting mutations within your DNA. And if enough mutations are aquired, then cancer can happen.
Brother, Im 99% sure your urine doesnt hold your DNA. Its an inorganic waste passed out by your body. However, it might contain something or other like a skin cell . But to answer your original question, seeing as urine doesnt contain DNA, I doubt they test it. Too expensive and time costly. So your off the hook if you give someone your urine, or vice versa. But if you admit to someone you did theyll prolly be upset.
