This step is used to danature DNA (separate two strands) by NaOH:
Denature the DNA by adding freshly prepared NaOH (3 M) to a final concentration of 0.3 M. Incubate at 42°C for 30 min.

How do alkali solutions denature DNA?
DNA has a double helix structure. This double helix structure exists, as the bases form hydrogen bonds (Adenine-Thymine form 2 hydrogen bonds and Guanine-Cytosine form 3 hydrogen bonds). In an alkali environment (mostly NaOH is used) the hydrogen bonds between the bases will be broken by the hydroxylic group (OH). Due to the breakage of the hydrogen bond, the double helix is broken, so two single DNA strands are obtained. Meaning the DNA is denatured.
Role of NaOH in plasmid DNA isolation?
Plasmid isolation involves growing the plasmid under conditions that are suitable for genes to come into play. For example the gene for ampicillin resistance; the bacteria with plasmids are placed with ampicillin so their genes can be seen for those who survived. Sodium hydroxide acts a detergent in the extraction process. A detergent's main role is to break down cell walls and cell membranes. How so? They act as poking holes into membranes. However, for the isolation of plasmid, the NaOH acts
What are the function of NaOH in the experiment of determination of solute concentration in solution using spectrophotometer?
NaOH is added to p-nitrophenol to change it into p-nitropenyl, which can give the maximum Absorption.
How do you make 0.1M solution of NaOH?
a solution of 0.1M NaOH has been prepared.How would you make 1L of the same solution
Is it possible to prepare a standard NaOH solution by dissolving an accurate amount of NaOH pellets in a known volume of water?
you can't make a primay standard solution with NaOh.as NaOh is said to be a secondary standard you have to establish the normality using some primary standard acids.
What is the purpose of using water bath in isolating DNA from cells?
The process of isolating DNA serves several purposes such as unlocking hereditary traits, determining paternity, and identifying unknown deceased bodies. Using water bath in isolating DNA from cells increases the yield of DNA by slowing down the enzymes that could break the DNA strand.
Why can't you extract DNA from cooked food?
DNA in cooked food is denatured (broken into bits and pieces) due to heat
How many stands are in DNA?
DNA is double-stranded, unless it has been denatured, then the two strands separate, forming two single-stranded molecules.

Are endotoxins denatured?
It depends on whether they are denatured or not.

NaOH is added to p-nitrophenol to change it into p-nitropenyl, which can give the maximum Absorption.
What is one thing that would need to be considered concerning the activity of this enzyme in PCR when the temperature is heated during each cycle to separate?
that the DNA polymerase could be denatured
A denatured protein or DNA molecules has lost what?
It has lost its active 3D structure and therefore it is not functional anymore.
Determination of the acid content of white wine?
Do a titration using NaOH of known concentration.
