During the formation of nucleic acid polymers, such as DNA and RNA, a molecule of water is removed in a process called condensation or dehydration synthesis. This occurs when nucleotides are linked together through phosphodiester bonds, forming the backbone of the nucleic acid. Specifically, the hydroxyl group from the 3' carbon of one nucleotide and the hydrogen from the 5' phosphate group of another nucleotide are eliminated to release water. This reaction is crucial for building the long chains of nucleic acids that store and transmit genetic information.

What part of the cell is typically removed during the cloning process?
The nucleus is typically removed during the cloning process, as it contains the genetic material of the donor cell. This nucleus is then inserted into an egg cell that has had its nucleus removed, leading to the formation of a cloned organism.
What is the end product of nucleic acid digestion?
The end product of nucleic acid digestion is nucleotides. During the digestion process, enzymes such as nucleases break down nucleic acids (DNA and RNA) into smaller units, eventually leading to the formation of individual nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base. These nucleotides can then be further metabolized or utilized for various cellular functions, including the synthesis of new nucleic acids.
What is the name of the process where one of these small units combine to form a more complex molecule?
The process where small units combine to form a more complex molecule is called polymerization. During polymerization, monomers—small, repeating chemical units—bond together to create polymers, which are larger and more complex structures. This process is fundamental in the formation of various materials, including plastics and biological macromolecules like proteins and nucleic acids.
What are Monomers of large macromolecules assembled during a chemical reaction called?
Monomers are the building blocks of large macromolecules, and when they are assembled together during a chemical reaction, they form polymers. Polymers are made up of repeating units of monomers linked together through covalent bonds.
In nucleic acids the free hydroxyl group is attached to the carbon of the sugar.?
In nucleic acids, the free hydroxyl group is typically attached to the 3' carbon of the sugar molecule in the nucleotides. This hydroxyl group is crucial for the formation of phosphodiester bonds during the polymerization of nucleotides into a nucleic acid strand. The presence of this hydroxyl group allows for the attachment of additional nucleotides, facilitating the growth of the nucleic acid chain. In contrast, the 5' carbon of the sugar is usually attached to a phosphate group, which plays a key role in linking nucleotides together.
How does dehydration synthesis contribute to the formation of nucleic acids?
Dehydration synthesis is a chemical reaction that links nucleotides together to form nucleic acids like DNA and RNA. During this process, a water molecule is removed, allowing the nucleotides to bond together. This contributes to the formation of nucleic acids by creating long chains of nucleotides that make up the genetic material in cells.
Are polymers made by dehydration?
Yes, polymers can be made by dehydration reactions. In polymerization, monomers are linked together by removing water molecules during the chemical bonding process. This results in the formation of long chains or networks of repeating units, known as polymers.
What molecule is removed during the formation of new bonds within a polypeptide?
During the formation of new bonds within a polypeptide, a molecule of water (H2O) is removed. This process is known as dehydration synthesis or condensation reaction, in which a hydroxyl (OH) group is removed from one amino acid and a hydrogen (H) atom is removed from the adjacent amino acid, resulting in the formation of a peptide bond.
What part of the cell is typically removed during the cloning process?
The nucleus is typically removed during the cloning process, as it contains the genetic material of the donor cell. This nucleus is then inserted into an egg cell that has had its nucleus removed, leading to the formation of a cloned organism.
What is the significance of the 3 prime carbon in the structure of nucleic acids?
The 3' carbon in nucleic acids is significant because it is where the next nucleotide is added during DNA or RNA synthesis. This carbon forms a bond with the phosphate group of the incoming nucleotide, allowing for the formation of a continuous chain of nucleotides.
What is the name of the process where one of these small units combine to form a more complex molecule?
The process where small units combine to form a more complex molecule is called polymerization. During polymerization, monomers—small, repeating chemical units—bond together to create polymers, which are larger and more complex structures. This process is fundamental in the formation of various materials, including plastics and biological macromolecules like proteins and nucleic acids.
What are nitrogenous wastes created from urine formation?
Nitrogenous wastes created during urine formation include urea, creatinine, and uric acid. These substances are byproducts of protein metabolism and the breakdown of nucleic acids. They are filtered by the kidneys and excreted in urine to maintain proper balance in the body.
What happens to monomerswhen they undergo dehydration synthesis?
They will break up into smaller molecules.
What are Monomers of large macromolecules assembled during a chemical reaction called?
Monomers are the building blocks of large macromolecules, and when they are assembled together during a chemical reaction, they form polymers. Polymers are made up of repeating units of monomers linked together through covalent bonds.
What molecule catalyzes covalent bond formation between DNA?
DNA ligase catalyzes the formation of covalent bonds between nucleic acid strands, such as DNA. It acts by joining the sugar-phosphate backbone of two DNA fragments together to repair DNA damage or during DNA replication.
How is information during protein synthesis?
From nucleic acids to amino acids
How many water molecules would be removed during the formation of a polysaccharides containing 240 monosaccharides?
239 water molecules would be removed during the formation of a polysaccharide containing 240 monosaccharides. This is because each monosaccharide molecule will contribute one water molecule in the dehydration synthesis reaction that forms the glycosidic bond between them.
