Answer: Option D
Explanation:
Hershey and Chase were the scientist that concluded that DNA is the genetic material which is transferred from one generation to another generation.
Before their experiment, people used to believe that protein is the genetic material.
Hershey and Chase conducted an experiment on bacteriophage where Radioactive phosphrous was transferred along with DNA in the cell.
This proved that DNA is the genetic material that transferred information from one generation to another.
Answer:
Proteins and polysaccharides.
Explanation:
Proteoglycans are heavily glycosylated proteins. These proteoglycans are present in the extracellular matrix of the animal cells and acts as a lubricant for the cells.
Proteoglycans are proteins that are covalently bonded with muco polysaccharidse. Proteoglycans are formed by the bonding between proteins and carbohydrates ( polysaccharides). Proteoglycans can combine with collagen to form cartilage and may affect the stability of a protein.
Thus, the correct answer is option (E).
