Can fire alter DNA?

Question

In the course of a fire can DNA be altered? Need this answer for a Fire Investigation Course.

Answer 1

yes if u heat dna it gets it gets denatured but u can renature it by cooling it u can do that in two ways 1 sudden cooling 2.annealing -u can cool it in steps

Answer 2

No DNA will remain as it is even if it was burnt out.....

If you put a DNA molecule in a hot water the double strands will be seperated a part but as soon as they are cooled they will be attached to each other again to make the same molecule. That was an example about applying high temprature to DNA molecules.

Also the DNA is used as the main factors to detect the relationships between species regarding the evolution point of view (that means the fossile found might have been in a fire or any other extrem hot conditions) and their DNA was found to be not affected and therefore used to detect thier similarities to each other.....

Answer 3

Fire is an example of oxidation; oxidation is a component of aging. Why? Because oxidation is thought to damage your cellular machinery and DNA. Oxidation is a highly reactive chemical process where oxygen is combined with a given molecule. Rust is an example of slow oxidation; fire an example of fast oxidation.

True DNA can be denatured by heat and then recombined, but oxidation itself can cause point-mutations and other types of damage.

I guess the true answer lies in whether you are talking about "naked" DNA, ie DNA lying outside an organism, or inside a body such as a human body.

Most organisms have capacity to deal with DNA damage, whether by repair of the DNA strand itself, or planned cellular death where non-viable cells with to much damage die off.

So, can fire damage DNA? Yes, it can, but your body has the ability to repair most damage.

Answer 4

well, it burns, and even extreme heat can destroy it.
I don't know if someone calculated the self-ignition temperature of dna.

please keep in mind that dna is a very stable molecule, it's stable at simple heating at 120°C. some modern PCR machines replicate dna at that temperature. (normal pcr works at 80°C)

Answer 5

tell me... whats existence made out of? No, its no longer DNA or RNA, you're able to desire to bypass extra advantageous than that. Its amino acids. particular, they have been created in a lab and it grew to become into blasted everywhere in the information approximately 10 years in the past yet each Christian interior the worldwide a manner or the different neglected the printed. Do you recommend "complicated existence"? Then no, no longer yet. yet elementary products like virus' easily. Others have already published hyperlinks at right here so which you will ensure so I won't positioned up them lower back. And enable me clarify this for toddler minds... lower back.... Evolution isn't the comparable element as Abiogensis. Abiogensis deals with the introduction of existence. to establish that Evolution to take place, the element could desire to already be alive. Evolution does not take place to rocks. you're yet another certainly one of those those that thinks by way of fact we've been learning technological awareness incredibly tricky for the final one hundred fifty years, we could desire to constantly unexpectedly *poof* comprehend each little thing in existance. It does not artwork that way. human beings at the instant are not gods and scientists do no longer declare to BE gods. we could desire to constantly be taught the thank you to do issues. It takes time. think of if we had constantly lived by skill of what you merely reported. you're able to nonetheless be living in caves. by way of fact it does not be achievable to EVER be taught something new. i'm hoping you have discovered to apply your suggestions for extra advantageous than "eat, sleep, intercourse" right this moment.

Answer 6

If you mean "burning" the DNA then yes it can. It will nto cause mutations, however.

Answer 7

Nope.

Answer 8

not possible

Answer 9

NO!
