using the process of bacterial transformtion, a student reseacher inserted a plasmid containing a gene for antibiotic resistance
Elena-2011 [213]

Transfer of newly created plasmids to e coli. The bacteria that contains a plasmid with antibiotic resistance will grow in the presence of antibiotic concludes that the insertion was successful.

<h3><u>Explanation:</u></h3>

The plasmid DNA that contains the foreign DNA when integrated with the competent bacteria which is e coli and heated,  plasmid DNA will be entering into the bacteria by means of some smaller pores that are created in the  membranes of the cell.

The plasmid DNA will be copied many times with the help of the replicating mechanism of DNA of the bacteria. Bacteria will grow on a nutrient rich food called agar after the transformation process. Those bacteria that contains a plasmid containing antibiotic resistance only grow in the antibiotic presence. Transformed bacteria will then grow in larger quantity.

Compare what life would be like living with sickle cell anemia versus living with tay sachs disease
Fantom [35]
<span>If I didn't know I had tay sachs (a genetic neurodegenerative condition), I would be terrified because of what I would perceive as a dysfunction of my brain. Once I were diagnosed with it, I would know there isn't any cure or treatment. I'd know that it would cause me to have a range of issues, such as paralysis, seizures and dementia. All of these would absolutely diminish my quality of life, both physically and emotionally, and shorten it. On the other hand, the effects on me of sickle cell anemia (a red blood cell disorder) would be comparatively less severe. It is treatable and manageable through diet, exercise, medication and other measures. The main symptions are pain, swelling and fatigue. Although the quality of my life would be significantly altered, at least I would feel I had options to mitigate its effects.</span>
