rattling good stories in Vietnamese folklore. However, Love Story Of My Chau And Trong Thuy is the best folktale I have ever heard since I was a child. It is involved in the important and true historical event in Vietnam. An Duong Vuong - a king of Au Lac nation, who built Co Loa citadel, was helped by saint Kim Qui. Then, the saint took him one of his claws to make a crossbow to protect the citadel from enemies. Because the crossbow was very magic, every arrow was shot from it to hit a thousand of

DISCUSSION In analyzing the effect of 2-aminopurine on mutation frequencies of bacterial strain CC102 (ara∆(gpt-lac)5 thi rpsL/F’ lacZ-Y+A+proA+B+ , the bacterial strain CC102 was cultured in LB medium with 2-aminopurine and one LB medium without 2-aminopurine. The bacterial strain CC102 with and without the 2-aminopurine mutagens were diluted to 10-5 and 10-6 and were plated on LB plates with nutrients and sources of carbon compounds for growth. The undiluted bacterial strain CC102 was then plated

can in fact breakdown lactose and have been coined lactose-fermenting (Lac+) strains. S. enterica has always naturally contained parts of the lac operon that is found in other bacteria such as E. coli, but it has never been functional and active until recent. The goal of this study was to identify what was necessary for S. enterica to be a Lac+ strain, the researchers did so by isolating an examining 13 different strains of Lac+ S. enterica and comparing it to other enterica bacteria. The researchers

to the galactoside (Wang, 2002). When looking at the lac operon regulation it is important to consider the lacI gene and the lac repressor- a protein, (UW-Milwaukee, 2017). The repressor is under the control of its own promoter and is expressed separate from the lac operon. In this experiment when lactose is available (the inducer) is bound to lacI it inactivates the lacI, losing its ability to bind DNA. This cascade results in the increase in lac operon transcription and thus β -galactosidase for

Different techniques beta-galactosidase activity can be regulated Beta galactosidase ca be regulated by use different techniques. There can be the addition of an inducer IPTG that continuously induce the expression of lacZ gene over time. It can also be through manipulating the promoter regulatory protein or by addition of different monosaccharide that are preferred over others. Beta galactosidase enzyme it binds to the lacZ gene repressor, this creates a positive feedback because in

Transposition Mutagenesis: Post-lab Questions Rebecca Herbert Friday Lab Section 1a. What is a transposon? A transposon is a section of DNA whose location can be moved, or transposed, from a plasmid to a chromosome, or vice versa. Transposons are necessary if recipient DNA are missing a sequence that complements the donor DNA. Also referred to as “jumping genes,” transposons are unlike typical DNA which usually does not move around, and are flanked by inverted repeat sequences which contribute to

complementation with their operons. Mutant phenotypes reveal themselves on certain medias. All of these reasons have contributed to why E. coli is so well researched. E. coli has an operon that codes for the breakdown of lactose. Within this lactose (Lac) operon, there are 6 total genes: LacI, LacP, LacO, LacZ, LacY, and LacA. LacI codes for the repressor that binds to the LacO operator (Hartl, 2011). The promoter region (LacP) is where RNA polymerase binds to begin transcription. LacZ codes for the

How does the J-1 visa program compare to the H-2 visa program? How do the employer sponsorship requirements, work protections, problems, and litigation trends, and other components of the programs compare? Short Answer The J-1 visa program is very unlike the H-2 visa program in design, oversight, and regulation. The J-1 visa program contains 15 different categories of participants, where some, such as secondary students, are generally not allowed to work. Furthermore, sponsor requirements for

money problems can result in people staying where they are. Luckily there are jobs where we can make a living off of our dreams. Being an au pair, traveling nurse, or graphic designers balances the situation of money and a way of travel. These jobs are also very diverse in terms of the working field. With advantages comes disadvantages each different for every job. Au pairs are not common in the United States but it is one of the best ways to travel, learn a new language, and get money all at the same
