3.We anticipate our recombinant DHFR protein to be functional for use in future research applications. However, if you had been able to test functionality and found that your recombinant GST-DHFR-His protein was not functional, what would you propose is one potential issue you would investigate to troubleshoot further. In other words, what is one thing that could have gone wrong to result in non- functional protein from the method used and results obtained this semester

Answers

Answer:

In the given case, the protein would have required to go through the process of post-translational modification, however, the mentioned protein would have been cultured in the prokaryotic system, the process of post-translational modification would have failed to take place. This step would be essential for the functionality of the protein. Thus, there is a need to culture it within the eukaryotic system.

The covalent and generally the enzymatic modification of proteins post its biosynthesis is termed as post-translational modification.

Despite their fundamental similarities, there are some striking differences between animal and plant cells (see Figure 1).

Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.

The correct sequence for the general adaptation syndrome is:_________
a) Exhaustion phase, alarm phase and resistance phase
b) Alarm phase, resistance phase and exhaustion phase
c) Resistance phase, exhaustion phase and alarm phase
d) Alarm phase, exhaustion phase and resistance phase

Answers

Answer:

The correct sequence for the general adaptation syndrome is: b) Alarm phase, resistance phase and exhaustion phase

Explanation:

The general adaptation syndrome describes what happens to our body when it is under stress.

The first phase is the Alarm phase. In this stage, the body activates the fight or flight response, causing an increase in adrenaline and cortisol, blood pressure, respiratory frequency, amongst other things that prepare us to react in a situation that we perceive as dangerous.

The second phase is the resistance one. During this phase, the body undergoes a different process that adapts it to manage the stress, with an elevated amount of cortisol and blood pressure.

The third phase is the exhaustion phase. If the stress levels continue to be high, the body passes to this stage. The body is exhausted and cannot keep dealing with stress, which causes mental and physical problems such as anxiety, depression, fatigue, stress-related illnesses, among other symptoms.

Scenario 1
When you think of the American Southwest, you probably think of cacti, both big and small. If you were to
visit the American Southwest today, you might be disappointed with the lack of variation among cactus
species, especially right off the major highways. In 1926, Route 66 was the nation's first major highway to
allow visitors to visit the Southwest. Like many tourists, these visitors wanted to take home a memento of
their travels. Many people would pull over and begin looking for their own living souvenir. Since many of the
tourists did not have the necessary tools to extract a spiny cactus out of the soil, they usually had to make a
conscious decision about what type of cactus they should dig up. The cacti with too many spines were seen
as too difficult to dig out, and the visitors likely didn't have gloves to protect their hands. The cacti with too
few spines were seen as homely and were often overlooked. Therefore, the tourists found a cactus that was
between these two extremes. Over the last century, the phenotypic variation within these small cacti has
changed (at least in areas accessible by these highways).
