Describe the operon hypothesis and discuss how it explains the control of messenger RNA production and the regulation of protein synthesis in bacterial cells. Blood groups and genetic drift. 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 most probable pattern of inheritance for this condition. 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.
Describe how modern techniques of molecular biology could be used to determine whether the mutant allele is present in a given individual. Describe a procedure by which this can be done. In most cases, neither parent of affected offspring has the condition. Explain how these alleles are distributed by the process of meiosis to gametes.
In a laboratory population of diploid, sexually reproducing organisms a certain trait is studied. What would be the effect of a deletion or an addition in one of the DNA nucleotides?
Describe the biochemical composition, structure, and replication of DNA. Include in your discussion a sample cross es sufficient to verify your proposed pattern. This disorder occurs with equal frequency in males and females. Do the following with reference to the Hardy-Weinberg model.
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. Explain the purpose of each step of your procedure.
Unit 7 Evolution, Population Genetics, Speciation Describe how you could determine whether the gene was successfully incorporated. Include in your answer a discussion of how the different types of RNA function in this process.
Assume that a particular genetic condition in a mammalian species causes an inability to digest starch. 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.
A portion of specific DNA molecule consists of the following sequence of nucleotide triplets. Explain how each of the following deviates from these conclusions.
Select one of the criteria stated above and describe experimental evidence used to determine that DNA is the hereditary material. Explain the evolutionary mechanisms that can change the composition of the gene pool. The mechanism of action of restriction enzymes. Explain how DNA meets each of the three criteria stated above.
The diagram below shows a segment of DNA with a total length of 4, base pairs. Describe the production and processing of a protein that will be exported from a eukaryotic cell. Describe the special relationship between the two terms in each of the following pairs. The arrows indicate reaction sites for two restriction enzymes enzyme X and enzyme Y.
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? Evolution is one of the major unifying themes of modern biology. Explain the mechanisms that lead to evolutionary change.
Discuss how recombinant DNA techniques may be used to correct a point mutation. A new population was created by crossing 51 pure breeding homozygous dominant individuals with 49 pure breeding homozygous individuals.
Experiments by the following scientists provided critical information concerning DNA. Explain how the events of meiosis I account for the observations that led Mendel to formulate these laws.
This trait is determined by a single autosomal gene and is expressed as two phenotypes. In rabbits the white color is due to a recessive allele, w, and the agouti is due to a dominant all, W. An organism is heterozygous at two genetic loci on different chromosomes.This question offered an opportunity to demonstrate fundamental knowledge about the Mendelian inheritance of single gene traits with complete dominance as well as the opportunity to recognize and explain the effects of gene linkage on phenotype.
