Concept explainers
To calculate: The water molecules that would remain between the membranes.
Concept introduction: There are many protein molecules involved in the fusion of vesicle. Membrane fusion is facilitated by bringing two lipid bilayer of membrane in close proximity, so that the lipid can flow from one bilayer to another. To accomplish the fusion, the water molecules must be displaced from the hydrophilic surface of the membrane.
To calculate: The number of phospholipids present in each of the opposing monolayers at the fusion site.

Membrane fusion is facilitated by bringing two lipid bilayer of membrane in close proximity, so that the lipid can flow from one bilayer to another. To accomplish the fusion, the water molecules must be displaced from the hydrophilic surface of the membrane.
To determine: Whether sufficient water molecules are present to bind to the hydrophilic head groups of nine phospholipids or not.

Talk about what atoms are. what they're made of, why chemical bonding is important to DNA?arrow_forwardWhat are the structure and properties of atoms and chemical bonds (especially how they relate to DNA and proteins).arrow_forward
- The Sentinel Cell: Nature’s Answer to Cancer?arrow_forwardMolecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forward
- Molecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed and translated, it produced a different protein than it produced in the eukaryotic cell. What is the most likely explanation?arrow_forwardMolecular Biology LIST three characteristics of origins of replicationarrow_forwardMolecular Biology Question Please help.
