Diamond Blackfan anemia (DBA) is a rare, dominantly inherited syndrome character

Question

Diamond Blackfan anemia (DBA) is a rare, dominantly inherited syndrome characterized by bone marrow failure, birth defects, and a significant predisposition to cancer. Those affected with DBA usually develop anemia in the first year of life, have abnormal numbers of cell types in their bone marrow, and have an increased risk of developing leukemia and bone cancer. At the molecular level, DBA is caused by a mutation in any of 11 genes that encode ribosomal proteins. The common feature of all these mutations is the disruption of ribosome formation, ultimately affecting the stability or function of ribosomes. Based on the given information, provide a brief discussion addressing how the following are potentially effected or play a role in the above diagnosis (a) DNA replication (b) Cell Division (c) Transcription (d) Translation.

Explanation / Answer

The DNA is a vital and key molecule in molecular biology ale the processes like transcription translation and etc are dependent on it for DNA replication and translation may proteins including ribosome are needed if there is defect in the gene it is pretty clear that the defective gene is going to get amplified and carry forward to the next cell generation via cell division.. thus affecting the central dogma of biology.
