Identify three sources of mutation that are spontaneous due to a cell's biochemistry rather than due to an outside mutagen.
Homework Answers
Mutations can be caused spontaneously at low frequencies due to the chemical instability of the bases of purine & pyrimidine & to the DNA replication errors. Major causes of the spontaneous point mutations are -
Deamination of the cytosine --> uracil in double helix of DNA.
The following replication results in mutant daughter cell & in it the C•G base pair gets replaced by T•A base pair.
Another source is the copying errors while DNA replication. Even though the process of replication is done with great accuracy, there is chance of errors to happen.
hope the answer helps.

Why is it better to rely on a variety of information sources for evaluation rather than just a few? Give some examples of how several sources are used in project evaluation. What are the advantages and disadvantages of the following sources of information: (a) charts and tables, (b) oral and written reports, (c) firsthand evaluation? What is the purpose of internal peer reviews? When are they held? Who participates?

If the CFTR doesn't work correctly due to a mutation, Cl^- movement is blocked and an abnormally thick sticky mucus is produced on the outside of the cell. This mucus clogs the airways in the lungs, and increases the risk of infection by bacteria. Figure 2 illustrates a mutant CFTR channel in the epithelial cells lining the lung. Suppose the Na^+ channel in the figure was open. Why would more Na^+ enter a cell with mutant CFTR than a cell...
