One approach that is becoming more common in drug D&D is to search for antimicrobial-producing organisms in relatively prist

ine environments. A pristine environment is one that has been relatively unperturbed by humans and/or domestic animals. Your D&D team is searching for novel antimicrobials produced by bacteria in a remote area of a temperate rainforest in the Pacific Northwest.
Which of the following terms would accurately describe your drug?

1. antibiotic
2. chemotherapeutic agent
3. natural
4. synthetic
5. semisynthetic

<h2>The term antibiotic accurately describe your drug.</h2>

Explanation:

  • <u>Antibiotics: </u>The bacterial infection are treated or prevented by the use of Antibiotics.
  • The antibiotic helps to kill bacteria or it prevent the bacteria,to spread in the body.
  • In viral infection such as cold and flu, Antibiotics do not work.
  • It is a bacteria that demonstrate antimicrobial activity in early testing.
  • The natural antibiotic is successfully extracted and purified from the bacteria.

A woman has blood type a mm. her child has blood type ab mn. the blood types of the potential fathers are given below.
goldfiish [28.3K]
The mother has the alleles A and M, given that her blood type is A MM. Since the child has blood type AB MN, then the child has the alleles A, B, M, N. However, the alleles B and N, cannot have come from his/her mother and must have come from the father. Therefore, we are looking for a father with the alleles B and N. Based on this conclusion, the child's father is either Tom (with blood type AB MN) or Bill (with blood type B MN).

24. How are vaccines used to keep people healthy?
riadik2000 [5.3K]

A vaccine can help keep people healthy and protect them from a certain virus. For example people in the United States get the flu shot when they get this shot the vaccine wont magically get rid of the virus but rather help them fight it off and protect them in the future if they keep up to date getting the vaccine

Thermophilic anaerobic bacteria are highly insensitive to ethanol. Scientists demonstrate that one of their membrane proteins X
BARSIC [14]

Answer:

Since high ethanol is a major stress during ethanol fermentation, ethanol-tolerant yeast strains are highly desirable for ethanol production on an industrial scale. A technology called global transcriptional machinery engineering (gTME), which exploits a mutant SPT15 library that encodes the TATA-binding protein of Saccharomyces cerevisiae (Alper et al., 2006; Science 314: 1565-1568), appears to be a powerful tool. to create ethanol tolerant strains. However, the ability of the strains created to tolerate high ethanol content in rich media remains to be demonstrated. In this study, a similar strategy was used to obtain five strains with higher ethanol tolerance (ETS1-5) of S. cerevisiae. When comparing the global transcriptional profiles of two selected strains ETS2 and ETS3 with that of the control, 42 genes that were commonly regulated with a double change were identified. Of the 34 deletion mutants available in an inactivated gene library, 18 were sensitive to ethanol, suggesting that these genes were closely associated with tolerance to ethanol.

Explanation:

Eight of them were novel and most were functionally unknown. To establish a basis for future industrial applications, the iETS2 and iETS3 strains were created by integrating the SPT15 mutant alleles of ETS2 and ETS3 into the chromosomes, which also exhibited increased tolerance to ethanol and survival after ethanol shock in a rich medium. Fermentation with 20% glucose for 24 h in a bioreactor revealed that iETS2 and iETS3 grew better and produced approximately 25% more ethanol than a control strain. The performance and productivity of ethanol also improved substantially: 0.31 g / g and 2.6 g / L / h, respectively, for the control and 0.39 g / g and 3.2 g / L / h, respectively, for iETS2 and iETS3.

 Therefore, our study demonstrates the utility of gTME in generating strains with increased tolerance to ethanol that resulted in increased ethanol production. Strains with increased tolerance to other stresses such as heat, fermentation inhibitors, osmotic pressure, etc., can be further created using gTME.
