Describe how modern techniques of molecular biology could be used to determine whether the mutant allele is present in a given individual. Describe each classical experiment and indicate how it provided evidence for the chemical nature of the gene.
Calculate, showing all work, the frequencies of the alleles and the frequencies of the genotypes in a population ofrabbits, of which 25, are white and 75, are agouti. 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.
The different results you would expect if a mutation occurred at the recognition site for enzyme Y. An organism is heterozygous at two genetic loci on different chromosomes. Indicate the conditions under which allelic frequencies p and q remain constant from one generation to the next.
Describe the operon hypothesis and discuss how it explains the control of messenger Ap biology essay questions biochemistry production and the regulation of protein synthesis in bacterial cells.
Explain how the principles of gel electrophoresis allow for the separation of DNA fragments. In most cases, neither parent of affected offspring has the condition. Describe the modern theory of evolution and discuss how it is supported by evidence from two of the following areas.
Do the following with reference to the Hardy-Weinberg model. The diagram below shows a segment of DNA with a total length of 4, base pairs.
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.
Explain how these alleles are transmitted by the process of mitosis to daughter cells. Birds of prey and DDT. Assume that the digestions occurred under appropriate conditions and went to completion.
Describe a procedure by which this can be done. Include in your discussion a sample cross es sufficient to verify your proposed pattern. Describe how scientists use each of the following as evidence for evolution.
After four generations, the following results were obtained. Include in your answer a discussion of how the different types of RNA function in this process.
Bacterial resistance to antibodies. Explain the mechanisms that lead to evolutionary change. The mechanism of action of restriction enzymes. Discuss how recombinant DNA techniques may be used to correct a point mutation. In a laboratory population of diploid, sexually reproducing organisms a certain trait is studied.
Describe the biochemical composition, structure, and replication of DNA. Describe how you could determine whether the gene was successfully incorporated. A portion of specific DNA molecule consists of the following sequence of nucleotide triplets. Assume that a particular genetic condition in a mammalian species causes an inability to digest starch.
What would be the effect of a deletion or an addition in one of the DNA nucleotides? 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 process of speciation.
Labeled diagrams that are explained in your answer may be useful. Genetic variation is the raw material for evolution. In rabbits the white color is due to a recessive allele, w, and the agouti is due to a dominant all, W.
Explain the purpose of each step of your procedure. Describe the results you would expect from the electrophoresis separation of fragments from the following treatments of the DNA segment above.
A new population was created by crossing 51 pure breeding homozygous dominant individuals with 49 pure breeding homozygous individuals.AP Biology Practice Free Response Question: Biochemistry On the AP Biology Exam this May, you will have 90 minutes to complete the free-response section that.
