GENE THERAPY Gene therapy is based on the concept that genetic disorders and acquired diseases can be treated by replacing abnormal or absent genes or by modifying their functions. Inherited disorders such as cystic fibrosis and haemophilia‚ as well as catastrophic diseases such as cancer and AIDS‚ are prospective candidates for gene therapy. Although cures for these ailments would be welcome‚ some medical researchers suggest that the range of diseases that can be treated with gene therapy may be

Introduction: The chemical industry has become one of the largest manufacturing industries in the world since the beginning of the 21st century (Murmann‚ 2003). They convert raw materials such as oil‚ natural gas‚ air‚ water‚ metals‚ and minerals into more than 70‚000 synthetic chemicals (United States Department of Commerce‚ n.d.). Heavy demands on chemicals allowed prosperity of materials goods and had brought convenience for many people. Now they can be found everywhere around world‚ and even

This gene makes a protein‚ called (pRb)‚ that helps stop certain cells from growing too quickly. In about 1 out of 3 children with retinoblastoma‚ the abnormality in the RB1 gene is present at the child’s birth and is in all the cells‚ including the retinas of the eyes. This is known as a germline mutation. Children born with a mutation in the RB1 gene usually develop retinoblastoma in both eyes‚ known as bilateral retinoblastoma

in the cells that line the air passages. The abnormal cells do not develop into healthy lung tissue; they divide rapidly and form tumours. As tumours become larger and more numerous‚ they undermine the lung’s ability to provide the bloodstream with oxygen. Tumours that remain in one place and do not appear to spread are known as “benign tumours”. Malignant tumours‚ the more dangerous ones‚ spread to other parts of the body either through the bloodstream or the lymphatic system. Metastasis refers

The Human Genome Project (HGP) was one of the great feats of exploration in history - an inward voyage of discovery rather than an outward exploration of the planet or the cosmos; an international research effort to sequence and map all of the genes - together known as the genome - of members of our species‚ Homo sapiens. The Human Genome Project was started in 1990 with the goal of sequencing and identifying all three billion chemical units in the human genetic instruction set‚ finding the genetic

What Is Retinoblastoma? Cancer of the eye is retinoblastoma its only happens in off springs. It is a disease of the very young children. Sixty-six percent of people with retinoblastoma are realized before they are two years old‚ and more than ninety percent of people have it before the growth of five. Retinoblastoma can take two forms or types: Around three-fourth percentage of offspring with retinoblastoma has one lump or tumor in one eyeball. This is named one-sided retinoblastoma‚ and it generally

Life is defined as the existence of an individual human being or animal. There is a plethora of controversy about when life truly starts. Does it start right when the sperm meets the egg? Does it start when the fetus develops enough to feel? Most have their own opinion on this topic‚ but if “killing” an embryo can save lives it might be worth it. General stem cell research has been going on for many years‚ but due to cut funding‚ advancements have been inhibited. It was cut because embryonic stem

chapter of foundations of genetics it shows us how genes influence traits. In this article it informs us about how people with down syndrome have the same genes as any other human being the only difference is that 1% extra. Genes have the power to control things such as a persons physical appearance‚ how the body ages‚ and the way we grow and develop.These genes are passed on from our parents. Going back to the chapter of DNA where it mentions that genes are made of DNA. As in the chapter of mitosis

chromosomes and because it is dominant‚ and Mendel’s Law of Dominance claims that some genes are dominant and are over the recessive genes which prevents the recessive gene from being present. Retinoblastoma forms during pregnancy when the tumor grows within the tissue that would be developing for the eyes. Retinoblastoma traces to one locus which includes chromosome 13 which codes for the RB1 tumor suppressor gene. RB1 codes by 928 amino acids and would be mutated by deletion‚ insertion‚ missense‚
