Boiling can allow for the extraction of DNA.
The living tissue is no longer living; it dies.
Yes boiling water does denature it. Boiling water will change the chemistry of the proteins causing it to denature, and other proteins can longer cling to the cells.
Dundas was here
you shop it/ put it in a bowl and mash it up, then add boiling water to help denature the cells and then you use a tray with dips in it and you add small samples of your filtered solution onto the tray, then you add drips of acids/ alkalies and you will notice a change of colour! Simple!!
Denature enzyme activity
to digest (denature) proteins - its stomach acid.
options (A) Boiling point (b) Colour (C) Smell (D) Solubility in water.
boiling water
Boiling an egg doesn't cause loss of protein, it does denature the protein and changes its form (changes from clear and runny to hard and white).

Enzymes are not alive, so they cannot be killed. Typically though, bringing an enzyme to a boiling temperature is enough to denature it. There's no evidence though that denatured enzymes in food at all affects the nutritional effects of the food.
Heat can definitely effects both types of cells. If cells become too hot or cold (or vary too far from their ideal temp.) they can denature and become useless.
:-D Yes! But one has to admit, they were always there.
yeah above 45degree C, it starts to denature
When bacteria are boiled the heat energy from the boiling water transfers through to the cells of the bacteria causing the water inside them to begin boiling as well. This increases the pressure inside the cells until they bursts, killing the bacteria. However boiling water will not have this effect on all bacteria.
If denature = dead then at high temperatures, high alcohol content, high/low pH
if u mean 'what are the factors that denature enzymes?' the answer is:--------- changes in pH and an increase in temperature
The cells are incubated in a hot water bath in order to denature the cytoplasmic enzymes which break apart DNA.
Temperature, pH, organic solvent, mechanical forces
heat it
