Are proteins more or less resistant to acid hydrolysis that are nucleic acids why?
Proteins are generally more resistant to acid hydrolysis compared to nucleic acids. This is because proteins have a more complex and stable structure due to their folded three-dimensional conformation, which makes them less susceptible to being broken down by acid. Nucleic acids, on the other hand, have a simpler structure and are more susceptible to breaking under acidic conditions.
Why formamide is used as a denaturant in dgge?
Formamide is used as a denaturant in Denaturing Gradient Gel Electrophoresis (DGGE) because it destabilizes the DNA double helix, leading to the separation of DNA fragments based on their sequence. By introducing formamide into the gel, different DNA fragments can be separated based on their melting temperature, allowing for analysis of genetic diversity and structure within a sample.
Why not use antibacterial or antiviral drugs to destroy prions?
Prions are not susceptible to antibacterial or antiviral drugs because they are not living organisms like bacteria or viruses. Prions are misfolded proteins that cause other proteins to misfold, leading to disease. They are resistant to most traditional forms of disinfection or drug treatment.
What are the main features of Prions?
Prions are misfolded proteins that can induce other proteins to also misfold, leading to protein aggregates in the brain. They are associated with neurodegenerative diseases such as Creutzfeldt-Jakob disease and mad cow disease. Prions are highly resistant to conventional sterilization methods and can be transmitted through contaminated meat or other tissues.
What are stable proteins?
Stable proteins are proteins that are resistant to denaturation or degradation under various environmental conditions, such as changes in temperature, pH, or presence of enzymes. These proteins maintain their structural integrity and function over a wide range of conditions, making them ideal for use in biotechnological applications or as therapeutic agents.
Are proteins less resistant or more resistant to acid hydrolysis that are nucleic acids?
they are more because they are
What are eubacteria with protective walls that are resistant to heat and cold.?
Thermophiles are eubacteria that are resistant to heat, while psychrophiles are eubacteria that are resistant to cold. These bacteria have protective cell walls made of unique proteins and lipids that help them survive extreme temperatures.
What is pyridine used for?
Pyridine is commonly used as a solvent in chemical reactions and as a precursor in the synthesis of pharmaceuticals, dyes, and insecticides. It is also used as a denaturant for ethyl alcohol, and as a reagent in various organic reactions.

Are transgenic crop plants registered for use in the US?
Yes. Most are herbicide resistant (soybean, canola) or produce insecticidal proteins (BT corn, cotton).

Which microorganism is least resistant to antimicrobial agents?
Prions are considered the least resistant microorganisms to antimicrobial agents because they lack the structures targeted by most antibiotics or disinfectants. Prions are composed mainly of misfolded proteins and are not easily killed by standard antimicrobial treatments.
Why are proteins more resistant to acid hydrolysis?
Proteins have complex three-dimensional structures that provide stability against acid hydrolysis. The amino acids in proteins are linked by peptide bonds, which are less susceptible to breaking in acidic conditions compared to other types of chemical bonds. Additionally, proteins may form compact structures that shield the peptide bonds from contacting the acid directly, further protecting them from hydrolysis.
What is wood alcohol for?
Wood alșcohol isa very old name for methanol -CH3OH. Some applications areȘ- solvent- denaturant for ethanol- antifreezing agent- fuel

Why is disinfectant resistant to disinfectant?
beause they contain some proteins called porins that show little permeability for hydrophilic solutes. these porins vary/change their structure to escape from antibacterial pressure or regulation.
