The arrows indicate reaction sites for two restriction enzymes (enzyme X and enzyme Y). Assume that a particular genetic condition in a mammalian species causes an inability to digest starch.
This disorder occurs with equal frequency in males and females. Include in your discussion the factors that may contribute to the maintenance of genetic isolation. Do the following with reference to the Hardy-Weinberg model. In a laboratory population of diploid, sexually reproducing organisms a certain trait is studied.
What would be the effects of a substitution in one of the nucleotides? Describe the operon hypothesis and discuss how it explains the control of messenger RNA production and the regulation of protein synthesis in bacterial cells. Scientists seeking to determine which molecule is responsible for the transmission of characteristics from one generation to the next knew that the molecule must (1) copy itself precisely, (2) be stable but able to be changed, and (3) be complex enough to determine the organism’s phenotype. Describe the biochemical composition, structure, and replication of DNA.
Discuss how recombinant DNA techniques may be used to correct a point mutation. Describe the production and processing of a protein that will be exported from a eukaryotic cell.
In most cases, neither parent of affected offspring has the condition. This trait is determined by a single autosomal gene and is expressed as two phenotypes.
A new population was created by crossing 51 pure breeding (homozygous) dominant individuals with 49 pure breeding (homozygous) individuals.Scientists recently have proposed a reorganization of the phylogenetic system of classification to include the domain, a new taxonomic category higher (more inclusive) than the Kingdom category, as shown in the following diagram.Universal Ancestor Domain Bacteria Domain Archaea Domain Eukarya (Eubacteria) (Archaebacteria) (Eukaryotes) Unit 10 (Vertebrates, Basic Animal Structure and Function) 39.Include in your discussion the major reactions, the end products, and energy transfers. The rate of photosynthesis may vary with changes that occur in environmental temperature, wavelength of light, and light intensity.Using a photosynthetic organism of your choice, choose only ONE of the three variables (temperature, wavelength of light, or light intensity) and for this variable 12.Select two of the following three pairs and discuss the evolutionary relationships between the two members of each pair you have chosen.In your discussion include structural adaptations and the functional significance.A portion of specific DNA molecule consists of the following sequence of nucleotide triplets.TAC GAA CTT GGG TCC This DNA sequence codes for the following short polypeptide.Include in your answer (a) a description of how you would set up and perform the experiment: (b) the results you would expect from your experiments: and (c) an explanation of those results based on the principles involved.(Be sure to clearly state the principles addressed in your discussion.) 9. Choose THREE of the following four types of cellular transport.
