Explain the evolutionary mechanisms that can change the composition of the gene pool. Describe the results you would expect from the electrophoresis separation of fragments from the following treatments of the DNA segment above. If the homozygous dominant condition were to become lethal, what would happen to the allelic and genotypic frequencies in the rabbit population after two generations?
Do the following with reference to the Hardy-Weinberg model. Explain how these alleles are transmitted by the process of mitosis to daughter cells.
In a laboratory population of diploid, sexually reproducing organisms a certain trait is studied. Indicate the conditions under which allelic frequencies p and q remain constant from one generation to the next. Bacterial resistance to antibodies.
Describe how modern techniques of molecular biology could be used to determine whether the mutant allele is present in a given individual. Describe the steps of protein synthesis, beginning with the attachment of a messenger RNA molecule to the small subunit of a ribosome and ending generalized with the release of the polypeptide from the ribosome.
Select one of the criteria stated above and describe experimental evidence used to determine that DNA is the hereditary material. Labeled diagrams that are explained in your answer may be useful.
The diagram below shows a segment of DNA with a total length of 4, base pairs. Begin with the separation of the messenger RNA from the DNA template and end with the release of the protein at the plasma membrane. Describe the operon hypothesis and discuss how it explains the control of messenger RNA production and the regulation of protein synthesis in bacterial cells.
Explain how each of the following deviates from these conclusions. By using the techniques of genetic engineering, scientists are able to modify genetic materials so that a particular gene of interest from one cell can be incorporated into a different cell.
The arrows indicate reaction sites for two restriction enzymes enzyme X and enzyme Y. This disorder occurs with equal frequency in males and females.
In most cases, neither parent of affected offspring has the condition.AP Biology Essay Questions The following is a comprehensive list of essay questions that have been asked on past AP exams. The questions are organized according to units.
