Why RNA can be hydrolyzed by dilute alkali but not DNA?
RNA contains a hydroxyl group on the 2' carbon of its ribose sugar, making it more prone to hydrolysis in alkali conditions. In contrast, DNA lacks this hydroxyl group due to a deoxyribose sugar, making it more stable and resistant to hydrolysis in alkaline conditions.
DNA is more resistant to hydrolysis than RNA what feature of DNA is responsible for this characteristic?
DNA has a deoxyribose sugar, which lacks a hydroxyl group compared to the ribose sugar in RNA. This absence of a hydroxyl group in deoxyribose makes DNA more resistant to hydrolysis because it is less prone to attack by water molecules.
What is the result of hydrolysis of a dipeptide?
Hydrolysis of a dipeptide results in the breaking of the peptide bond between the two amino acids in the dipeptide to yield two separate amino acids. This process requires the addition of water to break the bond, resulting in the separation of the amino acid components.
What does the hydrolysis of lipid molecules yield?
Hydrolysis of lipid molecules yields fatty acids and glycerol. This process breaks down lipids into their individual components, which can then be used by the body for energy production or to build new molecules.
Why RNA is unstable though it is single stranded but DNA is stable during double strand.?
Both DNA and RNA exist as single and double strands. yet the structure of a DNA is more stable then RNA. The main difference between the two nucliec acids is that DNA contains Deoxyribose and RNA contains ribose sugar which has a free hydroxyl group in its pentose ring which makes it prone for hydrolysis, thereby making it more unstable than the DNA.
The Monomer of RNA is?
Hydrolysis !!
What does hydrolysis of a simple protein yield?
Amino acids.
Why is RNA readily hydrolyzed by acid solutions?
RNA contains a ribose sugar that is vulnerable to hydrolysis when exposed to acid solutions. The acid can protonate the hydroxyl group at the C2 position of the ribose, leading to a breakage of the phosphodiester bond between nucleotides in the RNA chain. This results in the degradation of the RNA molecule.
Why do you use carrier RNA in extractions?
Carrier RNA is used in extractions to increase RNA yield, stability, and recovery. It helps to maximize the precipitation of RNA while reducing its degradation or loss during the extraction process. Carrier RNA also aids in the efficient isolation and purification of the target RNA by acting as a co-precipitant and increasing the effectiveness of RNA isolation reagents.
What does the hydrolysis of an acyl chloride give?
Unsurprisingly the hydrolysis of it will yield a carboxylic acid (COOH), and Hydrochloric acid, with the acyl end becoming a carboxylic acid.
How does zinc ion hydrolyze RNA?
Zinc in its most common +2 oxidation state is actually a fairly good Lewis acid will not hydrolyze RNA since RNA is quite stable at low pH. Chelated with imidazole or carboxylates, however, zinc can achieve a pKa of around 7, allowing for general base hydrolysis of RNA. For this reason imidazole buffers are generally not used with RNA unless RNA cleavage is desired.
What provide energy for RNA polymerase?
How energy for movement RNA polymerase on DNA provide
Why RNA can be hydrolyzed by dilute alkali but not DNA?

What is the monomer of RNA?
The monomer of RNA is a ribonucleotide, which consists of a ribose sugar, a phosphate group, and one of four nitrogenous bases (adenine, cytosine, guanine, or uracil). These ribonucleotides link together through phosphodiester bonds to form an RNA molecule.
DNA is more resistant to hydrolysis than RNA what feature of DNA is responsible for this characteristic?
DNA has a deoxyribose sugar, which lacks a hydroxyl group compared to the ribose sugar in RNA. This absence of a hydroxyl group in deoxyribose makes DNA more resistant to hydrolysis because it is less prone to attack by water molecules.
Role of te in dna extraction?
TE stands for Tris and EDTA. The Tris buffers the water to prevent acid hydrolysis of the DNA/RNA. The EDTA chelates divalent cations that can assist in the degradation of RNA.
What reaction does nuclease catalyze?
Nucleases catalyze the hydrolysis of phosphodiester bonds in nucleic acids, resulting in the cleavage of DNA or RNA molecules. This enzymatic activity allows nucleases to degrade or fragment nucleic acids.
