Answer: Phosphorous
Explanation:
Phosphorous can be used to label Nucleic acid. Nucleic acids can be modified or labelled using tags .
Some common materials or substances that can be used to label nucleic acids are flurophore, enzymes, radioactive phosphorous, biotin et cetera.
The nucleic acid of virus is labelled using phosphorous. When this virus will infect the host cell then nucleic acids will be seen separately.
Answer:
As the saltier blood circulates through the body, it makes the fluid outside of our body cells saltier than the fluid inside the cells. The cells notice the change right away. That's because the extra salt outside acts like a magnet, pulling water out of the cells.

Answer:
There should be 10% thymine
Explanation:
DNA bases come in specific pairs. Guanine pairs up with cytosine and adenine pairs up with Thymine.
According to the problem the DNA sample was 40% cytosine and 40% guanine, so this is correct, there are equal amounts of cytosine and guanine. Now Thymine needs to have equal amounts as adenine, but adenine only has 10%.
If we match up the amount of adenine to thymine, we would have 15% adenine and 15% thymine, but that would excede 100%. So you need to match the thymine to adenine.
10% adenine + 10 % thymine + 40% cytosine + 40% guanine = 100%
Answer:
The correct answer is: B. If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children.
Explanation:
- The inheritance of genes from the parents to the offspring is mediated by the germinal cells or sex cells or gametes of the parents.
- The genetic material present in the somatic cells of the parents are not transmitted to the offspring.
- In the given case, the man who develops lung cancer generates some tobacco smoke induced mutations in some of the cells of his lungs.
- The cells of the lungs are type up of somatic cells. Hence, any mutations in the genome of these cells will never be transmitted to the offspring.
- Therefore, the children of the man will never become prone to develop lung cancer due to development of mutations in the lung cells of the man.
- However, if the man has inherited any mutation from his parents which can increase the risk of development of lung cancer, then these mutations will be present in his germinal cells and also in some of his gametes.
- Now, if a child is born due to the fusion of the the maternal gamete with one of these mutated paternal gametes, there is an increased chance of developing lung cancer in the child, irrespective of the fact whether he is a smoker or a non-smoker.
