What is the pH of DNA?
The pH of DNA is typically around 7.5 to 8.0, which is slightly basic. DNA is a negatively charged molecule due to the phosphate groups in its structure, which can affect its interactions with other molecules in different pH environments.
Function of tris HCl in DNA isolation?
Tris HCl is used as a buffer in DNA isolation to maintain a stable pH level during the process. It helps to prevent pH fluctuations that can affect the integrity of the DNA molecule. Tris HCl also aids in the solubilization of proteins and DNA, ensuring efficient extraction of DNA from the sample.
Why are acidic substances lower in pH value than basic substances?
Acidic substances have higher concentrations of hydrogen ions (H+) which results in a lower pH value compared to basic (alkaline) substances. A lower pH value indicates a higher concentration of H+ ions, while a higher pH value indicates a higher concentration of hydroxide ions (OH-) found in basic substances.
The process that makes an exact copy of a cell's DNA is called?
The process that makes an exact copy of a cell's DNA is called DNA replication. During replication, the DNA double helix unwinds and each strand serves as a template for the synthesis of a new complementary strand, resulting in two identical DNA molecules.
Determining the exact order of nucleotides in DNA is called?
Determining the exact order of nucleotides in DNA is called DNA sequencing. This process helps in identifying the sequence of bases (adenine, thymine, cytosine, and guanine) in a DNA molecule, which is crucial for understanding genetic information and studying various biological processes.
What side effects could occur if the DNA pH value is altered If the milk's pH value is known, it can be adjusted?
If the milk's pH value is known, it can be adjusted. Mini theory Like a nature
What is the exact value of every color on pH scale in decimals?

Can an indicator provide an exact pH?
An indicator can provide exact pH if you are using the neutralization titration. Paper strip pH indicator are not an exact measurement but a high, medium, and low indication of acids and bases.
What is PH value of KHCO3?
The pH value of potassium bicarbonate (KHCO3) in water is around 8-9, making it slightly alkaline. However, the exact pH value can vary depending on the concentration of the solution and other factors.
What is the pH level of simple soap?
The pH of water soap solutions is low basic. The exact value depends on the type and producer.
What is the pH of a solution containing H2S?
The pH of a solution containing H2S would be acidic, as H2S is a weak acid. The exact pH value would depend on the concentration of H2S in the solution.
What is an advantage of using the 4.5-7.5 paper pH?
when both substances had a pH value of about 6 on the 0-14 paper
PH value of blood?
The pH value of blood is normally around 7.35 to 7.45, making it slightly alkaline. Maintaining this narrow pH range is crucial for the proper functioning of enzymes and other biochemical processes in the body. Deviations from this range can lead to health problems or even be life-threatening.
Does lithnus paper tell the exact pH?
Litmus paper provides a general indication of whether a substance is acidic or basic based on a color change. It does not provide an exact pH value but can give you a rough idea of the acidity or basicity of a solution. For precise pH measurements, a pH meter would be more suitable.
If a few drops of universal indicator is added to water changes red what pH value is it?
Its Ph value is less than 7, so it is acidic. The exact colour change needs to be compared visually with a standard universal indicator chart to determine the precise Ph value associated with that particular shade of red.
What pH is radium hydroxide?
Radium hydroxide is a strong alkaline compound, so it would have a high pH value. However, the exact pH would depend on the concentration of the radium hydroxide solution.
What is the pH value for radium chloride?
The pH value of radium chloride cannot be determined directly as it is a salt. However, when radium chloride dissolves in water, it will form a weakly acidic solution due to the formation of hydrochloric acid in the solution. The exact pH will depend on the concentration of the radium chloride solution.
