Concept explainers
a.
To determine: Whether, any of the suspects can be excluded as the one who committed the crime based on the results of the testing, or not.
Introduction: The genetic material of an individual is packed in the form of DNA. The evidence collected by the police is a small bloodstain from which the DNA is extracted and the fragments are separated with the help of electrophoresis. The separated fragments are transferred to a membrane where they are probed with radioactive DNA.
b.
To determine: The suspect which can be excluded as the one who committed the crime with a plausible reason.
Introduction: The genetic material of an individual is packed in the form of DNA. The evidence collected by the police is a small bloodstain from which the DNA is extracted and the fragments are separated with the help of electrophoresis. The separated fragments are transferred to a membrane where they are probed with radioactive DNA.
c.
To determine: Whether the pattern from the evidence is consistent with the band pattern of one of the suspects, or not and also determine the suspect with which it is consistent.

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. Thank you For E coli DNA polymerase III, give the structure and function of the b-clamp sub-complex. Describe how the structure of this sub-complex is important for it’s function.arrow_forward
