Sounds a lot like a lab...
Answer:
Explanation:
Here, cell C-2 needs to express GFP and therefore, GAL4 should be functional in cell C-2. This can be achieved by expressing GAL4 in Regulatory DNA construct 3, and expressing GAL80, an inhibitor of GAL4 in Regulatory constructs 1 and 2. This arrangement expresses GAL4 in columns A and C, and inhibits GAL4 due to GAL80 expression in Columns A and B; and in rows 1 and 3.
Therefore, the only cell that expresses GAL4 is cell C-2.
The arrangement is:
1. Construct 1 should express GAL80
2. Construct 2 should express GAL80
3. Construct 3 should express GAL4
4. Construct 4 should not be used
Answer:
The answer is A.
Explanation:
During logarithmic growth phase bacteria grows exponentially doubling every x minutes (x depends on the species). In this question doubling time/generation time is every 15 minutes and log phase takes 5 hours, which equals to the 300 minutes. During 300 minutes bacteria doubles 20 times (300/15 = 20) which equals 2^20. Bacteria culture has been started with 1000 bacterial cells so it must be added to the calculation therefore right answer is: 1000 X 2^20.
Answer: Cell Wall
Explanation: Both archaea and bacteria have a/n Cell Wall, but it is made of peptidoglycan in bacteria and pseudo peptidoglycan in archaea.
Option (B) Transgenics is the correct answer.
Transgenics involves one or more DNA sequences being artificially introduced into an organism that wouldn't usually have them.
<h3>What is Transgenics?</h3>
- The term "transgenic" refers to organisms with modified genomes.
- For scientific investigation, most transgenic organisms are produced in laboratories. A particular gene of interest is disabled in transgenic mice called "knock-out" mice.
- Researchers can learn more about the normal operation of the gene by researching its consequences.
- It is possible to alter the genomes of living things with contemporary genetic technology. The term "genetic engineering" also applies to this method.
- Additionally, commercial uses for transgenic organisms have been created.
- Food crops like soy and peas that have undergone genetic modification to become resistant to pesticides and herbicides are probably the most well-known examples.
Hence, Transgenics entails the artificial introduction of one or more DNA sequences into an organism that wouldn't typically contain them.
