Several entities do not contain DNA, including certain viruses, which may have RNA instead of DNA as their genetic material. Additionally, non-living things such as rocks, water, and minerals do not possess DNA, as they are not biological entities. Furthermore, structures like prions, which are misfolded proteins, do not contain DNA or RNA.
What else can I help you with?
How do the structures of the purines and pyrimidines increase the accuracy of DNA replication?
Accuracy or fidelity of replication doesnt depend on DNA bases, the fidelity or keeping the DNA as correct is accompanied by DNA polymerase enzyme!
Why is it important for DNA is replicated before a cell divides?
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.
Why you freeze the pellet during DNA isolation?
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.
Why doesnt DNA rip during cell division?
DNA doesn't rip during cell division due to several protective mechanisms. Firstly, DNA is tightly coiled and packaged into structures called chromosomes, which helps prevent damage. Additionally, the cell has sophisticated repair systems that can quickly address any potential breaks or errors in the DNA. Finally, during cell division, the processes of replication and separation are highly regulated, ensuring that the DNA is correctly duplicated and distributed to daughter cells without tearing.
Is adding repeats of DNA at the ends of chromosome a kind of mutation?
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).

What happens in meiosis 1 that doesnt occur in meiosis 2?
dna is copied
What part of the DNA molecules is DNA named after?
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.
DNA test came out negative is the science can be wrong?
science doesnt lie it just states the facts.
If your DNA is 99 percent the same as monkeys doesnt that mean you are different?
Yes it does. The question is how different (or how similar)?

What is the secret ben 10 DNA code for Buzzshock or Megawatt?
RTWP and this will work in 2009. that doesnt work and its already 09
What is the Ripjaws DNA Bandai code?
This toy doesnt have one. I own 3 of them for my child. I just checked right now.
What part of a plant cell stores information?
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.
Is hyper beam going to look like DNA strands in Pokemon Heart Gold or Soul Silver?
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.
Is your DNA tested in a probation drug test and can you get in trouble for giving someone urine to pass a drug test.?
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.
What does a carcinogen form that gives a person cancer?
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.
