Currently, there are more than 600 genetic disorders known, all caused by defective genes. Genetic disorders result from the accumulation of the harmful substance in the body or from an inability of the body to produce or utilize essential substances that influence development and function. Most of the time genetic disorders are passed down through family, however, sometimes they can also be due to gene mutation caused by a combination of both genetic changes and other environmental factors. In order to understand what cause the gene mutation one must need a basic knowledge of genetics and biology and it all comes down to the cell, DNA, and genes.

DNA codes for protein by protein synthesis. In protein synthesis, there are two major steps; transcription that creates mRNA and translation that translation mRNA to translate into protein. Transcription happens in the nucleus, after the process of transcription, mRNA molecule is then sent to the ribosome where the message is translated into specific proteins. This process is called gene expression. Millions of cells in the human body contain about 23,000 genes that make up the human genome. Genes contain the information passed from parent to offspring and these passed down genes instruct cells on how to function and what traits to express. In other words, a gene regulates which genes to turn on and off in different patterns to control function. Through the gene expression, heredity determines behavioral and physical characteristics and substantially some diseases as …show more content…
Also, know that it’s mostly genetic but random gene mutations or mutation by environmental exposure can also cause hemophilia. Hemophilia is dangerous because when normal people get a cut or wounds, platelets close the hole and release chemicals that activate proteins in the blood. These clotting factors work together with the platelets to create a scab to close up and stop the bleeding. However, people with hemophilia lack or miss either factors VIII (8) or IX (9) or factor XI that helps exposed tissue factor to bind in order to initiate extrinsic
