Simply put, heat will denature DNA. Technically speaking, DNA has something known as the the melting temperature (which is the temperature at which a strand of DNA is separated halfway). And melting temperature is itself dependent on several other factors (like G to C ratio, salt conent, and pH).

What is the purpose of using detergent in extracting plant DNA?
Detergent denatures (breaks up) proteins, which can then be precipitated and the DNA can be isolated
Which molecule is responsible for separating double-stranded DNA into single strands?
At high temperatures, DNA denatures into single strands. A temperature around 95 degrees should work.
Why heat DNA to 94 degrees?
depends what you intend to do, usually in a pcr reaction it denatures the DNA so you get 2 seperated strands
What happens to the activity of an enzyme on either side of its temperature optimum?
Lower temperature: The energy input increases the flexibility of bonds in proteins. Higher temperature: Too much energy makes the bonds between the proteins brake and the protein unfolds 'denatures'
Is a DNA a plant or animal cell or both?
DNA is in both cells.
What does heat do to the DNA polymerase?
Heat denatures protein. DNA polymerase is an enzyme and a protein.
What does ctab use for isolation of DNA from animal blood?
CTAB is a detergent used to denature proteins from samples. Once the protens have been denatures, the isolation of DNA from the non required waste materials can begin.
How many replication forks are produced when DNA denatures at an origin?
2
How does a large change in temperature or PH effect proteins?
It denatures it.
What is the purpose of using detergent in extracting plant DNA?
Detergent denatures (breaks up) proteins, which can then be precipitated and the DNA can be isolated
What does DMSO do in hybridization buffers?
it denatures your DNA. So you get ssDNA that can hybridize more easily.
Which molecule is responsible for separating double-stranded DNA into single strands?
At high temperatures, DNA denatures into single strands. A temperature around 95 degrees should work.
Role of beta-mecaptoethanol in DNA isolation?
beta- merceptoethanol denatures the protein by breaking the sulphur bridges in it.
What happens to the enzyme when it is cooled below its best working temperature?
When an enzyme coola below a temperature where it can work, it denatures (dies).
Why does the rise in temperature decrease the affinity of hemoglobin for oxygen?
The rise of temperature denatures the bond between oxygen and hemoglobin.
What temperature denatures sucrase?
Sucrase denatures at approximately 50-60 degrees Celsius (122-140 Fahrenheit, and 323-333 kelvin) I am pretty sure this is accurate for anyone who is struggling
When enzymes are placed in extreme pH or temperature conditions they unwind and change shape This is called what?
The enzyme 'denatures'
