Summary Introduction

a.

To determine:

The results that would be expected if a laser is used to destroy one of the four cells of the embryos of early C. elegans and early mouse.

Introduction:

The model organisms are non-human species that help researchers to understand biological processes. They are generally easy to cultivate and rapidly produce a large number of progenies.

Summary Introduction

b.

To determine:

The results that might be expected if the four cells of the embryo are separated from each other and allowed to develop.

Introduction:

Organisms may use different strategies to accomplish the same developmental goal. For example, early C. elegans embryos show mosaic determination and early mouse embryos show regulative determination.

Summary Introduction

c.

To determine:

The multicellular organism exhibit countless strategies for development during the course of evolution. It creates a difference between mosaic and regulative determination patterns of development.

Introduction:

The model organism is easy to grow, and they quickly give birth to a large number of progenies. Therefore, geneticists can find rare mutations and study their behavior through successive generations.

Concept test: Please discuss thoroughly. The easily observed external structures in insects, such as different pairs of legs, antennae, and wings form from imaginal discs. a.) How is the identity of the different Drosophila imaginal discs established in the embryo—for example, how is it determined whether a disc will form a wing, a leg, or some other structure? b.) Dominant mutants in the gene Antennapedia result in fore legs forming in the location where antennae are expected. How does this mutant phenotype illustrate your response to Part a?

Concerning the Tools of Genetics Box Analysis ofCell-Cycle Mutants in Yeast:a. Describe how you would use replica plating ofmutagenized, haploid yeast cells to identifytemperature-sensitive (ts) mutations in essentialgenes needed for yeast growth and survival.b. Among the many ts mutations you found in part(a), how would you distinguish mutations in genesneeded for cell-cycle progression from those ingenes needed for other aspects of the life of yeasts?c. If you had a large collection of yeast cell-cyclemutants, how would you determine which of themutations are in the same gene and which are indifferent genes?

In a tissue engineering experiment, stem cells are grown in a circular dish (diameter = 3 cm) with a thin layer of cell culture media covering the cells. It is expected that these cells will differentiate when exposed a new differentiation factor (small molecule) at a surface concentration of 50 ng/cm? During the experiment, 1 ug of the factor is placed at the center of the dish. Assume the diffusivity of the factor in cell culture media is 1 x 10^-5 cm^2/s. A. How long does it take before the cells 1 cm from the center of the dish begin to differentiate? B. Do you expect the cells at the edge of the dish differentiate? Justify your answer with calculations.
