Teaching Human Genetics with Mustard: Rapid Cycling Brassica rapa  (Fast Plants Type) as a Model for Human Genetics in the Classroom Laboratory We have developed experiments and materials to model human genetics using rapid cycling Brassica rapa, also known as Fast Plants. Because of their self-incompatibility for pollination and the genetic diversity within strains, B. rapa can serve as a relevant model for human genetics in teaching laboratory experiments.apid cycling Brassica rapa, also known by the trademarked name Wisconsin Fast Plants, are an ideal organism for instruction. They complete their life cycle in 35–45 d (Williams and Hill, 1986) and grow at room temperature in potting soil fertilized with commonly available house plant fertilizer.

Brassica Crops from this genus are sometimes called cole crops —derived from the Latin caulis, denoting the stem or stalk of a plant. Members of brassica commonly used for food include cabbage, cauliflower, broccoli, Brussels sprouts, and some seeds as in the production of canola oil.The genus is known for its important agricultural and horticultural crops and includes a number of weeds, both of wild taxa and escapees from cultivation.n the division of a large number of plants in the plant kingdom into the groups monocotyledon and dicotyledon all members of Brassica are dicotyledons.

- The entire genome of one M. tuberculosis strain has been sequenced, and the M. leprae genome sequence will soon be completed. These dangerous, very slow growing mycobacterial pathogens are difficult to manipulate. Mycobacterium genes are poorly expressed from their own promoters in E. coli. Therefore the relatively fast growing, non-pathogenic M. smegmatis is often used as a host strain for gene cloning.

Using Research Organisms to Study Health and Disease Model organisms are a small group of research organisms that serve as a proxy for understanding the biology of humans. Examples include yeast, fruit flies, worms, zebrafish, and mice. Many aspects of these organisms’ biology are similar to ours, and much is already known about their genetic makeup. For these and other reasons, studying model organisms helps scientists learn more about human health. Why are model organisms useful for studying diseases? Drosophila.

Brassica Food Plot Forage Profile My first brassica food plot was planted in May of 2000, the plants grew to nearly a foot by late June, and by July the entire crop was completely consumed. There was no frost, a deer population of less than 15 per square mile and this is key: There were no quality forages within 20 miles!

Transgenic Organisms Modern genetic technology can be used to modify the genomes of living organisms. This process is also known as “genetic engineering.” Genes of one species can be modified, or genes can be transplanted from one species to another. Genetic engineering is made possible by recombinant DNA technology.Organisms that have altered genomes are known as transgenic.Most transgenic organisms are generated in the laboratory for research purposes. For example, “knock-out” mice are transgenic mice that have a particular gene of interest disabled.enetic engineering is made possible by recombinant DNA technology.

- Bacillus thuringiensis produces the Cry crystal toxin that attacks the gut of pests and kills them internally. These Cry toxins are good agricultural tools for growing plants. Instead of using chemicals that may have adverse effects on humans, genetic engineers integrate the Bt toxin into the plant's genome.These Bt Cry toxins are safe for humans and kill off species of pests that are susceptible to the Bacillus thuringiensis endospore.enome structure. B. thuringiensis has a circular chromosome and a GC-content of approximately 32%~35%. It has a genome size of between 5.2–5.8 Megabases.[11] It is a facultative anaerobic organism (an organism that makes ATP by aerobic respiration if oxygen is present but can also switch to fermentation).

G is for GMOs â What are GMOs & Why Do Farmers Plant GMO Crops? So basically, a GMO (genetically modified organism) is a plant, crop, food or something related to those things that was created with biotechnology. There are several kinds of GMOs, all of them involve taking a gene from one species and putting it into another unrelated species.ere is an example that probably everyone can understand – the gene that gets inserted into Roundup Ready plants is a petunia gene, because they are naturally resistant to Roundup. So, they essentially are taking a desirable element from an innocuous plant (our lovely petunia plant) and insert that ‘piece’ into crops.

Hemophilus influenzae Classification and Characteristics. Bacteria of the genus Haemophilus are small, non-motile gram negative bacilli and coccobacilli, and are fastidious by nature. They characteristically require certain growth factors, namely heme (X factor) and nicotine adenine dinucleotide (NAD or V factor). These growth requirements are used in the clinical setting to identify suspect organisms to the species level. Haemophilus spp. grow best at a temperature between 35o and 37o Celsius, at a slightly alkaline pH of 7.6.

- Genetically modified bacteria were the first organisms to be modified in the laboratory, due to their simple genetics.These organisms are now used for several purposes, and are particularly important in producing large amounts of pure human proteins for use in medicine.imilar bacteria have been used to produce clotting factors to treat haemophilia, and human growth hormone to treat various forms of dwarfism. These recombinant proteins are safer than the products they replaced, since the older products were purified from cadavers and could transmit diseases.

Insect-resistant Crops Through Genetic Engineering When the cell carrying the Bt gene is grown into a plant, the plant produces a protein that is toxic to the Colorado potato beetle. When the beetle feeds on the genetically improved plant, the toxic protein interferes with its digestive system and it dies.he Bt gene with the resistance gene attached is inserted into plant cells. At this point, scientists must determine which plant cells have successfully received the Bt gene and are now transformed. Any plant cell that has the Bt gene must also have the resistance gene that was attached to it.
