What else can I help you with?
Does RNA contain phosphodiester bonds?
Yes, RNA contains phosphodiester bonds. These bonds link the nucleotides together in the RNA molecule.
Do polypeptide bonds hold nitrogen bases together?
The nitrogen bases, adenine, uracil, guanine, thymine and cytosine are joined to each other via phosphodiester bonds. Hydrogen bonds hold the nitrogen bases in complementary DNA and RNA strands. Polypeptide bonds are formed between an amide and ketone, and these join amino acids in proteins. However, they do not hold nitrogen bases together.
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 is the significance of phosphoester bonds in biological molecules?
Phosphoester bonds are important in biological molecules because they are key components of nucleic acids like DNA and RNA. These bonds help to link nucleotides together, forming the backbone of these essential molecules that carry genetic information and play crucial roles in cellular processes.
Type of bonds that hold sugar and phosphates together?
Covalent bonds hold sugar and phosphate molecules together in DNA and RNA. These bonds are strong and stable, forming the backbone of the nucleic acid structure.
What structures is held together by hydrogen bonds?
Hydrogen bonds hold together molecules such as DNA strands, protein secondary structures like alpha helices and beta sheets, and between water molecules. These bonds are important for maintaining the structure and function of these biological molecules.
What bond holds purine bases and pyrimidine bases together?
Hydrogen bonds hold purine bases (adenine and guanine) and pyrimidine bases (cytosine, thymine, and uracil) together in DNA and RNA molecules. These hydrogen bonds form between specific pairs of bases, with adenine always pairing with thymine (or uracil in RNA) and guanine always pairing with cytosine.
Does RNA contain phosphodiester bonds?
Yes, RNA contains phosphodiester bonds. These bonds link the nucleotides together in the RNA molecule.
Do polypeptide bonds hold nitrogen bases together?
The nitrogen bases, adenine, uracil, guanine, thymine and cytosine are joined to each other via phosphodiester bonds. Hydrogen bonds hold the nitrogen bases in complementary DNA and RNA strands. Polypeptide bonds are formed between an amide and ketone, and these join amino acids in proteins. However, they do not hold nitrogen bases together.
Is nucleic acid a covalent or ionic?
Nucleic acids are composed of covalent bonds. The backbone of DNA and RNA is made up of a series of covalent bonds between sugar and phosphate molecules, while hydrogen bonds between nitrogenous bases hold the two strands of DNA together.
How are complementary nitrogenous bases held together?
Complementary nitrogenous bases are held together by hydrogen bonds. Adenine pairs with thymine (or uracil in RNA) by forming two hydrogen bonds, while cytosine pairs with guanine by forming three hydrogen bonds. These hydrogen bonds provide the necessary stability for the base pairing in DNA and RNA molecules.
Why there are no hydrogen bonds present in RNA?
Hydrogen bonds are indeed present in RNA, particularly between complementary bases in the double-stranded regions of RNA molecules, such as between adenine and uracil (or thymine) and between guanine and cytosine. These hydrogen bonds are essential for maintaining the structure and stability of RNA molecules.
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 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.
