What is the physical state of dna after being denatured by heat?

Biology

navik [9.2K]4 years ago

I believe when DNA is denatured by heat, hydrogen bonds are separated to create single stranded DNA. When the DNA solution is heated enough, The double stranded DNA unwinds, and the Hydrogen bonds that hold the two strands together weaken and finally break. The process of breaking a double-stranded DNA into single strands is known as DNA denaturation, or DNA melting.

The answer would be single-stranded

When DNA denaturated, the hydrogen bonds will be separated. This cause the DNA structure becomes single stranded. 
Heating DNA is used for replicating DNA(PCR) because as the DNA <span>unwinded </span>it is exposed and the enzyme to synthesize nucleic acid bind into it.

At which of the following temperatures is the speed of a given chemical reaction the fastest?
Rashid [163]
There are many factors that affect the rate of chemical reactions and temperature is one of them.
Typically, the higher the temperature of a chemical reaction the faster the reaction occur, that is, the temperature and the rate of chemical reaction are directly related. This is due to the fact that increasing the temperature of the reaction increases the kinetic energy of the reacting particles and thus they are able to move faster and the reaction also occur faster. Thus, from the options given, the correct answer will be D [40 degree], this is because, it is the highest temperature out of all the options given.

Brilliant_brown [7]

Answer:

<em>C. The bird population moved into and adapted to many different environments on the Hawaiian Islands.</em>

Why:

<em>When a species </em><em>adapts</em><em> itself to new environments certain features will change, such as beak size, wing use, and even height, these are all changed depending on what the species does and needs to survive. These birds all changed food sources which made them have to adapt their beaks over time to new sources, and natural color to over generations camouflage themselves better from predators.</em>

<em>(Hope this was a good explanation.)</em>
