Dehydration synthesis is a chemical process that links nucleotide monomers together to form DNA molecules. During this process, a water molecule is removed, allowing the nucleotides to bond together through covalent bonds. This helps in the formation of the long chains of nucleotides that make up the DNA molecule.

Dehydration synthesis and hydrolysis are accomplished in cells by?
Dehydration synthesis is achieved by removing a water molecule to build new molecules, while hydrolysis breaks down molecules by adding a water molecule. In cells, dehydration synthesis is carried out by enzymes that catalyze the formation of new chemical bonds, while hydrolysis is facilitated by enzymes that break down complex molecules into simpler components. Both processes play crucial roles in cellular metabolism and the synthesis and breakdown of biological molecules.
What role does energy play in the synthesis of complex molecules?
Energy plays a crucial role in the synthesis of complex molecules by providing the necessary power for chemical reactions to occur. These reactions require energy to break and form bonds between atoms, allowing for the creation of larger and more intricate molecules.
What role does RNA polymerase play in the process of protein synthesis?
RNA polymerase is an enzyme that helps in the transcription of DNA into RNA during protein synthesis. It catalyzes the formation of an RNA molecule that carries the genetic information from the DNA to the ribosomes, where the actual protein synthesis takes place.
What is the one job in whack most RNA molecules are involved?
RNA molecules are most involved in protein synthesis, specifically in the process of translation where messenger RNA (mRNA) is decoded by ribosomes to produce proteins. RNA molecules such as transfer RNA (tRNA) and ribosomal RNA (rRNA) play key roles in this process by carrying amino acids and forming the ribosome structure, respectively.
What role do large polar molecules play in the formation of biological membranes?
Large polar molecules, such as phospholipids, play a crucial role in the formation of biological membranes by arranging themselves in a bilayer structure. This bilayer acts as a barrier that separates the internal environment of cells from the external environment, allowing for selective permeability and maintaining cell integrity.

Both processes play crucial roles in cellular metabolism and the synthesis and breakdown of biological molecules.
What does RNA synthesis produce?
RNA synthesis produces RNA molecules using a DNA template as a guide. This process, known as transcription, involves the synthesis of mRNA, tRNA, and rRNA, which play essential roles in protein synthesis and other cellular processes.
What role does energy play in the synthesis of complex molecules?
Energy plays a crucial role in the synthesis of complex molecules by providing the necessary power for chemical reactions to occur. These reactions require energy to break and form bonds between atoms, allowing for the creation of larger and more intricate molecules.
What is the role of water molecules in polysaccharide formation?
Water molecules play a crucial role in polysaccharide formation as they are used in the condensation reactions that link sugar monomers together to form polysaccharides. During this process, water molecules are removed in a dehydration reaction, allowing the monomers to bond together and form longer chains.
What role does RNA polymerase play in the process of protein synthesis?
RNA polymerase is an enzyme that helps in the transcription of DNA into RNA during protein synthesis. It catalyzes the formation of an RNA molecule that carries the genetic information from the DNA to the ribosomes, where the actual protein synthesis takes place.
What role in transcription play in protein synthesis?
RNA molecules are produced by copying part of the nucleus sequence of DNA into a complementary sequence in RNA.
Polymerization and the breakdown of a polymer are two opposite reactions What role does a water molecule play in both of them?
In polymerization, a water molecule is often eliminated as a byproduct in a condensation reaction between monomers. This process is known as dehydration synthesis. In the breakdown of a polymer via hydrolysis, water molecules are used to break the covalent bonds between monomers, resulting in the degradation of the polymer into its constituent monomer units.

This bilayer acts as a barrier that separates the internal environment of cells from the external environment, allowing for selective permeability and maintaining cell integrity.
What molecules must pass between nucleus and cytoplasm?
Molecules that must pass between the nucleus and cytoplasm include mRNA (messenger RNA), tRNA (transfer RNA), and proteins. These molecules play crucial roles in gene expression and protein synthesis within the cell.
Does tRNA have proteins?
Yes, tRNA molecules do not have proteins. They are small RNA molecules that play a key role in protein synthesis by carrying specific amino acids to the ribosome during translation.
What is the center of protein synthesis?
Ribosomes play important role in the protein synthesis.
