Answer:
Option (4).
Explanation:
Hypersensitivity may be defined as the hyper immune response of the body. Hypersensitive is also known as hyper sensitive reaction that may be uncomfortable and harmful for the individual.
Type IV hypersensitive reaction is also known as delayed type of hypersensitivity that are generally mediated by T cells. Hemolytic disease of new born is an example of Type II hypersensitive reaction and not related to Type IV hypersensitive reaction.
Thus, the correct answer is option (4).
Answer:
Approximately 20,500 genes
Explanation:
The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.
