Answer:
don't know i have the same question
Explanation:
Answer:
Fab or fragment antigen binding
Explanation:
Treating the antibody with a protease can cleave this region, producing Fab. that include the variable ends of an antibody. Material used for the studies .The constant region determines the mechanism used to destroy antigen. Antibodies are divided into five major classes, IgM, IgG, Iga, IgD, and IgE, based on their constant region structure and immune function.
<u>ANSWER:</u>

<u>EXPLANATION:</u>
- Bloom syndrome is a heredity disorder which causes reduced height and develops skin rashes when exposed to sunlight. This may lead to formation of skin cancer.
- Haploinsufficiency is a condition in which one allele is inactive and the existing allele is not sufficient to produce the required gene product for the normal function.
- BLM is a gene required for the making of a protein called RecQ helicase.
- There is no cure for the bloom syndrome and children with this disease should be given proper nourishment.
- Bloom syndrome occurs due to the 'mutation of the BLM gene' located in the 15th chromosome.
