Describe the fluid-mosaic model of a plasma membrane. Include a description of mitosis and cytokinesis, and of the other phases of the cell cycle. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.
Discuss the role of the membrane in the movement of materials through it by each of the following processes: 6. Indicate the ways in which a nonphotosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell. Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions.
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 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.
Include in your answer a discussion of how the different types of RNA function in this process. The diagram below shows a segment of DNA with a total length of 4,900 base pairs.
Describe the light reactions of photosynthesis and, for both a C3 and a C4 plant, trace the path of a carbon dioxide molecule from the point at which it enters a plant to its incorporation into a glucose molecule.
Include leaf anatomy and biochemical pathways in your discussion of each type of plant. Explain what occurs during the Krebs (citric acid) cycle and electron transport by describing the following: 15. For 3 of the following 5 processes involving energy transfer, explain how each functions in the cell and give an example.
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.
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.
