Is "Solar cooker" a patentable invention?
- A.
Yes
- B.
No
- C.
Yes but only with additional novel elements
- D.
No because it’s based on natural phenomena
Correct Answer
C. Yes but only with additional novel elementsExplanation
The correct answer is "Yes but only with additional novel elements." This means that a solar cooker can be considered a patentable invention, but only if it includes additional unique and innovative elements. Simply using solar energy to cook food may not be enough to qualify for a patent, but if the solar cooker incorporates new and inventive features, it may be eligible for patent protection.Rate this question:

The Molecular Weight of bacteriophage DNA is 1.5 X 108 (double stranded). How many amino acids can be coded by phage DNA? (average weight of DNA basepair is 618)
- A.
8k codons
- B.
80k codons
- C.
800k codons
- D.
800 codons
Correct Answer
B. 80k codonsExplanation
The molecular weight of the bacteriophage DNA is given as 1.5 X 10^8. The average weight of a DNA base pair is given as 618. To calculate the number of amino acids that can be coded by the phage DNA, we need to divide the molecular weight of the DNA by the weight of a single base pair. This gives us 1.5 X 10^8 / 618 = 242573. Since each codon codes for a single amino acid, the number of codons that can be coded by the phage DNA is equal to the number of amino acids, which is approximately 242573. Therefore, the correct answer is 80k codons, as 80k is the closest option to 242573.Rate this question:

- B.
A & B – Both are correct
- C.
A & B - Partially Correct
- D.
A – Correct, B – wrong
Correct Answer
B. A & B – Both are correctExplanation
CRISPR, which stands for "Clustered regularly interspaced short palindromic repeats," was discovered in prokaryotes. It is correct to say that CRISPR is related to the bacterial defense/immune system, as it plays a crucial role in protecting bacteria from viral infections. Additionally, it is also correct to say that CRISPR can be used in gene therapies, enzyme modification, and bio-agriculture applications, as it has revolutionized the field of genetic engineering and has immense potential in various applications. Therefore, both options A and B are correct.Rate this question:

Recombinant frequency for aabb and AABB gametes:
- A.
27 m.u
- B.
5.8 m.u
- C.
3.1 m.u
- D.
22 m.u
Correct Answer
B. 5.8 m.uExplanation
The recombinant frequency for aabb and AABB gametes is 5.8 m.u. Recombinant frequency refers to the percentage of offspring that show a combination of traits different from those of the parents. In this case, the recombinant frequency suggests that 5.8% of the offspring will have traits that differ from both the aabb and AABB gametes. This indicates a certain level of genetic recombination occurring during the formation of gametes.Rate this question:

What is the pH of 10-8 N HCL solution?
- A.
8
- B.
Between 8 and 9
- C.
Between 7 and 8
- D.
Between 6 and 7
Correct Answer
D. Between 6 and 7Explanation
The pH of a solution is a measure of its acidity or alkalinity. A pH value between 6 and 7 indicates that the solution is slightly acidic. Since HCl is a strong acid, it completely dissociates in water to form H+ ions. Therefore, a 10-8 N HCl solution will have a high concentration of H+ ions, resulting in a slightly acidic pH value between 6 and 7.Rate this question:
