The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.
The quantity and quality of DNA can be greatly improved by performing PCR.
* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.
The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.
Explanation:
This experiment was conducted to investigate the selective permeability of dialysis tubing. The permeability of the tubing to glucose, starch, and iodine (potassium iodide) was tested. The dialysis tubing was clipped to form a bag so that glucose and starch were fed into the bag through the other end, and was also clipped to avoid the seeping of the solution.

Answer:
The Articular cartilage.
Explanation:
Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Healthy cartilage in our joints makes it easier to move. It allows the bones to glide over each other with very little friction. Articular cartilage can be damaged by injury or normal wear and tear.
