What enzyme breaks down RNA?
RNase (ribonuclease) is an enzyme that breaks down RNA molecules by cleaving the phosphodiester bonds that link RNA nucleotides together. It is involved in various cellular processes such as RNA degradation, RNA processing, and RNA quality control.
What bonds hold RNA molecules together?
RNA molecules are held together by covalent bonds, such as phosphodiester bonds in the sugar-phosphate backbone. In addition, RNA molecules also form hydrogen bonds between complementary bases (A-U and G-C) in the double-stranded regions.
Is phosphodiester bonds used to link nucleotides?
Yes, phosphodiester bonds are used to link nucleotides in a nucleic acid molecule, forming the sugar-phosphate backbone. These bonds connect the 3' carbon of one nucleotide's sugar group to the 5' carbon of the next nucleotide in the chain.
What is the significance of the 3' OH group in RNA synthesis?
The 3' OH group in RNA synthesis is important because it allows the addition of new nucleotides to the growing RNA strand. This group acts as a site for the formation of phosphodiester bonds between nucleotides, enabling the sequential assembly of the RNA molecule.
What does hydrolysis of RNA yield?
Hydrolysis of RNA yields ribonucleotides, which are the individual units that make up RNA. This process breaks down the RNA molecule into its constituent ribonucleotides through the addition of water molecules that break the phosphodiester bonds between the nucleotides.
Do nucleic acids contain a peptide bond?
No, nucleic acids do not contain peptide bonds. Peptide bonds are specific to proteins, linking amino acids together. Nucleic acids, such as DNA and RNA, are composed of nucleotides linked by phosphodiester bonds, which connect the sugar of one nucleotide to the phosphate group of another.
What bond is between nucleic acids?
In producing a strand of DNA the nucleotides combine to form phosphodiester bonds.
Where do you find phosphodiester bonds?
Phosphodiester bonds are commonly found in nucleic acids, such as DNA and RNA. These bonds form between the phosphate group of one nucleotide and the hydroxyl group of another nucleotide, creating the backbone of the nucleic acid molecule.

What provide energy for RNA polymerase?
How energy for movement RNA polymerase on DNA provide

What type of bonds holds the sugar and phosphate groups together?
Phosphodiester bonds hold the sugar and phosphate groups together in DNA and RNA molecules. These bonds form between the phosphate group of one nucleotide and the 3'-hydroxyl group of the sugar in the adjacent nucleotide.
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.
What is phosphodiester?
A phosphodiester bond is a group of strong covalent bonds between a phosphate group and two 5-carbon ring carbohydrates (pentoses) over two ester bonds. Phosphodiester bonds are central to all life on Earth, as they make up the backbone of the strands of DNA.
What is the significance of the 3' OH group in RNA synthesis?
The 3' OH group in RNA synthesis is important because it allows the addition of new nucleotides to the growing RNA strand. This group acts as a site for the formation of phosphodiester bonds between nucleotides, enabling the sequential assembly of the RNA molecule.
What bonds nucleotides into chains?
Nucleotides are bonded into chains by phosphodiester bonds. These bonds form between the phosphate group of one nucleotide and the hydroxyl group of the sugar of the next nucleotide, creating a sugar-phosphate backbone. This linkage occurs during the process of DNA or RNA synthesis, facilitated by enzymes such as DNA polymerase or RNA polymerase.
