Why does RNA have a 2' OH group?
RNA has a 2' OH group because it helps stabilize the molecule's structure and allows for flexibility in folding, which is important for its various functions in gene expression and protein synthesis.
Is maltose lost by the dehydration synthesis?
No. Maltose is formed by bonding two glucoses together through dehydration synthesis. Dehydration synthesis involves removing the OH group from one molecule or group and an H from the OH group in another group or molecule. This allows the two two bond together, releasing a water molecule from the lost OH and H (H2).
What primer is needed at the origin of nucleotide addition?
A primer made of RNA is required at the origin of nucleotide addition for DNA replication. This primer provides a free 3' OH group for DNA polymerase to start adding nucleotides and serves as a starting point for DNA synthesis.
Unlike DNA RNA contains?
Unlike DNA, RNA contains the sugar ribose instead of deoxyribose, and the nitrogenous base uracil instead of thymine. RNA is typically single-stranded while DNA is double-stranded, and RNA is involved in protein synthesis and gene expression.
Nucleotides contain which sugars?
DNA is composed of deoxy ribose nucleotide (containing deoxy ribose sugars). Deoxy ribose sugar lacks an OH group at the 2' position RNA is composed of ribose nucleotides (containing ribose sugar)

What is the difference between ribonucleotides and deoxyribonucleotides?
The main difference is the presence of a hydroxyl (-OH) group on the 2' carbon of the ribose sugar in ribonucleotides, whereas deoxyribonucleotides lack this hydroxyl group. This small difference affects the stability and structure of RNA and DNA molecules. Ribonucleotides are used for RNA synthesis while deoxyribonucleotides are used for DNA synthesis.

A primer made of RNA is required at the origin of nucleotide addition for DNA replication. This primer provides a free 3' OH group for DNA polymerase to start adding nucleotides and serves as a starting point for DNA synthesis.
RNA is chemically similar to DNA except that the sugar in RNA has an additional?
The ribose sugar in RNA has an additional oxygen, which holds a hydrogen, thus making it a hydroxyl group.
What is the function of primers?
RNA primers are used to initiate the DNA replication at the template strand. DNA molecules require a free 3' OH, to which it could add the nucleotides. This free 3' OH is provided by the RNA primer. So prior to the synthesis of DNA a short fragment of RNA is synthesized that is later excised and filled with DNA molecules.
What is a sugar group of RNA?
A sugar group in RNA refers to the ribose sugar molecule that forms the backbone of the RNA molecule. It is a crucial component that helps make up the structure of RNA, along with the phosphate group and nitrogenous bases. The ribose sugar in RNA differs from the deoxyribose sugar in DNA by having an extra hydroxyl (-OH) group.
Unlike DNA RNA contains?
Unlike DNA, RNA contains the sugar ribose instead of deoxyribose, and the nitrogenous base uracil instead of thymine. RNA is typically single-stranded while DNA is double-stranded, and RNA is involved in protein synthesis and gene expression.
Why is the 3'OH group on the deoxribose ring so important in DNA synthesis?
because the DNA particles in the nuclear rub around the sinep anigav and coil to produce the synthesis
Which molecules are components of an RNA nucleotide?
An RNA nucleotide is composed of three main components: a ribose sugar, a phosphate group, and a nitrogenous base. The ribose sugar distinguishes RNA from DNA, as it contains an -OH group on the 2' carbon. The nitrogenous bases in RNA include adenine (A), uracil (U), cytosine (C), and guanine (G). These components combine to form the building blocks of RNA molecules.
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 RNA extraction is difficult?
RNA itself difficult to handle because of its unstable nature. Unlike DNA, RNA has free 2'-OH group in their ribose sugar that make them highly reactive. Other than this, RNAse contamination is everywhere (during isolation RNAase from our skin can kill RNA).
