But this rule rule is applicable only for double stranded DNA molecule. The possibility of Adenine=40% and Thymine=60% is only in single stranded DNA molecule. In the question, the DNA sample referred is a single stranded DNA. hope it helps :D
Answer: The most affected would be organs that have QUICKLY dividing cells (like the intestine and hair follicles).
Explanation:
Cancer cells are cells that divides uncontrollably giving rise to a mass of tissue called tumour. They grow faster than a normal cell in an uncoordinated manner, and continues to grow after the initial stimulus has ceased.
Paclitaxel is a drug that is approved for the treatment of cancer affecting different parts of the body. It's a microtubule-stabilizing drug whose mechanism of action is to induce mitotic arrest in the cancer cells.
Paclitaxel in its cause of action not only affect cancer cells but normal cells as well. To justify this statement, as stated earlier, the mechanism of action of paclitaxel is to induce mitotic arrest. Therefore the cells of organs where rapid mitosis occurs would be most affected. Skin cells, hair follicles and the cells lining our intestines (epithelial cells) all have high rates of mitosis as these tissues constantly need to be replaced.
c disruption of animal habitats
Explanation:
One of the likely effect of large scale infrastructural development is that it can lead to the disruption of animal habitats.
To develop new infrastructure, new areas have to be cleared to install the facilities and this can lead into encroachment of animal habitats.
- Oil drilling projects are capital intensive ventures undertaken by exploration and production companies.
- The oil is usually found in geologic formations deep within the earth crust.
- To access this fuel, large drilling ventures must be undertaken in order to accommodate to technology and man power.
- New areas have to cleared and this can push the habitat of organisms backward

Answer:
Pyruvate kinase is the important enzyme that catalyzes the conversion of phosphoenol pyruvate into the pyruvate in the glycolysis cycle. This step generates the ATP molecule.
The regulation of the pyruvate kinase is done by the allosteric regulation and fructose 1,6 biphosphate activates the pyruvate kinase. This regulation is important as it control the metabolites present in different organs. The metabolites like fructose, galactose enters in the glycolysis from the liver after the particlar step of glycolysis.
Answer:
viruses are at the borderline of living and non-living organinsms outside the body of living host they are non-active and they cannot grow without their host
