Answer:
it is a failure of tolerance (self-tolerance) and specificity (recognition)
Explanation:
Type 1 diabetes is a chronic disease caused by the selective destruction of β cells that are involved in the production of insulin in the pancreas. Type 1 diabetes can be classified into two types: Type 1A diabetes (the immune form of the disease) and Type 1B diabetes (the non-immune form of the disease). Type 1A diabetes is considered an autoimmune disorder where immune responses against pathogens suffer a failure of tolerance to antigens in the β-cells of the pancreatic islets. Thus, Type 1A diabetes is characterized by the process of recognition of β-cell antigens (autoantigens) by the immune system. This disease is often caused by genetic factors associated with mutations in the human leukocyte antigen (HLA) class II region located on chromosome 6.
Answer:
Option (A).
Explanation:
Epigenetics may be defined as the study of the heritable phenotype changes that do not change the sequence of DNA. The gene activity or gene expression changes in epigenetics. Environment may also brings the changes in gene expression.
The change in phenotype of the individual must be inherited in epigenetic changes. The chromatin must be modified but the nucleotide sequence remains unaltered in epigenetic changes.
Thus, the correct answer is option (A).
Answer:
A cell wall, chloroplasts, plastids, (and in some cases vacuoles but they are sometimes present in both)
