Answer:
The correct answer is: DNA.
Explanation:
- DNA or Deoxyribonucleic acid is the genetic material that is transmitted from the parents to the offspring.
- It encodes for genes that gives rise to one of the most important structural and functional unit of cells, that is, the Proteins.
- The DNA is composed of a double helical backbone, made up of alternate deoxyribose sugar and phosphate groups linked by phosphodiester bonds. Each sugar molecule is linked to a nitrogenous base, purine or pyrimidines.
- The purines are Adenine(A) and Guanine(G) and the pyrimidines are Thymine(T) and Cytosine(C).
- Adenine of one strand of the helix forms two hydrogen bonds with the Thymine on the other strand and the Guanine of one strand of the helix forms three hydrogen bonds with Cytosine on the other strand.
- In some organisms, RNA or Ribonucleic Acid functions as the genetic material.

Explanation:
Answer:
Pros of HeLa cells:
- HeLa cells are immortal ,easy to maintain and can be kept alive.
- HeLa cells easily contaminate cell lines and thus can be incorporated easily into target tissues.
Cons of HeLa cell:
- The HeLa cells can easily contaminate cell lines and a lack of regular monitoring leads to unwanted contamination of cell lines resulting in wastage.
Explanation:
HeLa cells are immortal cells that are used in scientific and medical research. These were obtained from Henrietta Lacks , a cervical cancer patient. These cells are well known for their immortality, rapid growth and high contamination rate. These were unique cancerous cells that kept on dividing and remained alive easily.
