Summary Introduction

To review:

The description of two alternate models that explain that the mutant lacking RegA and RegB protein is unable to express the yxx gene and the results from ChIP-on-chip analysis that distinguish between the possibilities.

Introduction:

A technique that is used to recognize and select individuals that have a phenotype in a mutagenized population is known as mutagenesis screening. The phenotypic screen is also a type of genetic screen. They offer essential information on gene role. DNA (Deoxyribonucleic acid) interacts with the protein and this is generally followed by gene expression. Thus, proteins are also involved in regulating gene expression.

You are investigating the activity of different cadherins in cells. You use recombinant DNA technology to express GFP-E-cadherin (green) in some L-cells (which do not normally contain cadherin) and YFP-P-cadherin (yellow) in other L-cells. Explain results you expect in three cultures containing: (1) only cells expressing GFP-E-cadherin, (2) only cells expressing YFP-P-cadherin, and (3) a mixture of GFP-E-cadherin-expressing and YFP-P-cadherin-expressing cells. Also predict how (a) knocking down the ability of the cells to synthesize fibronectin (FN) or (b) adding EGTA, which depletes free Ca2+ concentration in the culture medium, might affect the results.
Boll weevil is a serious pest of cotton crop. Effective control involves applications of chemical insecticides, increasing the cost of production and environmental pollution. The current genetically modified Bt crops have allowed great benefits to farmers but show activity limited to lepidopteran pests. This work reports on procedures adopted for integration and expression of a cry transgene conferring resistance to boll weevil and fall armyworm by using molecular tools. Four Brazilian cotton cultivars were microinjected with a minimal linear cassette generating 1248 putative lines. Complete gene integration was found in only one line (TO-34) containing one copy of crylla detected by Southern blot. Protein was expressed in high concentration at 45 davs after emergence (dae), decreasing by approximately 50% at 90 dae. Toxicity of the cry protein was demonstrated in feeding bioassays revealing 56.7% mortality to boll weevil fed buds and 88.1% mortality to fall armyworm fed leaves. A…
After you have successfully cloned Sonic Hedgehog into pSELECT-CCFP-blasti and transfected HEK 293 cells (human embryogenic kidney cells), you observed, using confocal microscopy that the GFP fluorescence displays a reticulate network pattern in the cytoplasm of the cells. Describe an approach you can use to determine the subcellular localization of the Sonic Hedgehog-GFP fusion protein.
