What is Gene therapy?
Gene therapy is the process of supplementing or replacing a gene in order to treat a medical condition. This type of therapy allows the body to make the protein that is not being made by the missing or malfunctioning gene. Introduction of new genes through vectors overrides the malfunctioning gene and contributes to normal functioning of the body. The process begins when the modified DNA is inserted into a virus vector. Then, the vector binds to the cell membrane. After the vector binds to the cell membrane, a vesicle forms around the vector as it enters the cell. Thereafter, the vesicle breaks down, releasing the vector. Then, the vector inserts the DNA it contains into the cell’s nucleus. The cell makes a functional

Normally cancer cells that make CD-47 escape the immune system, by turning off CD-47 the immune system was able to target cancer cells. Herpes virus was modified to not cause soars and injected in the body it bonded to cancer cells, which lead the cancer cells to die. It also attracted immune cells to help fight cancer. Treatment for cancer like chemo therapy, radiation treatment, and surgery have high risk of damaging body cells. Gene therapy is accurate and only affect cancer cells. Gene therapy has worked, for example a one-year-old girl named Layla was saved from aggressive leukaemia, after all other treatment options failed, thankfully gene therapy worked. On the other hand, gene therapy has unintentionally caused cancer in hundred of patients in clinical trials. After intense gene therapy a total of 2 patients have died as a direct result of gene treatment. Gene therapy also causes many other negative side effects for example:

Unwanted Immune system reaction = Since your immune is made to protect your body, it might possibly attack the newly viruses as intruders. This may cause inflammation, and some serve cases organ

    Our immune system is reliable for killing harmful things that cause diseases. Immune systems with cancer cells are lacking cells with genes and no faults, so the purpose of this treatment is to add genes to aid with finding foreign dangerous cells such as cancer. This treatment is typically used with patients with breast cancer. The second type of treatment consists of the general gene therapy to make cancer treatments more effective. This therapy inserts genes into cancer cells to make the cells more sensitive to die to particular treatments such as chemotherapy or radiotherapy.…

    After the replication process of DNA the new strand of DNA would just wind up to create a double helix. Transcription is making RNA part of a gene sequence. This is when DNA is copied into RNA which would make it a messenger RNA (mRNA). The Mrna molecule is able to leave the nucleus and go to the cytoplasm where it sends messages for the synthesis of…

    DNA replication takes place in the nucleus. DNA is present here, because it allows for better protection from degradation, and provides a barrier from harmful effects. In order for DNA to be replicated, the DNA helix must be unwound. DNA helicase breaks apart the hydrogen bonds between the base pairs of the strands. Next, short strands of RNA, called the RNA primers, are synthesized by an enzyme called primase.…

    Gene cloning is usually associated with gene modification which occurs when a genetic engineer cuts the gene and replaces some of it with new material. Reproductive cloning happens when a mature somatic cell is removed from an organism, and the DNA is transferred to an egg cell whose DNA has been removed. This is commonly referred to as somatic cell nuclear transfer or SCNT. Finally, the egg starts the reproductive process and attaches to the uterus of a female in the same species. This results in a whole organism with the same genetic makeup of the donator of the somatic cell (See Appendix B for a diagram of the process).…

    The wide field of biochemistry includes exploration in the use of gene therapy for the treatment of cancers such as lung cancer. Though gene therapy is still in early stages of development, many researchers have concluded that gene therapy in therapeutic cancer treatment seems to be very effective and efficient. Gene therapy is the replacement of defective genes to enable the production of normally functioning genes. This replacement of genes is an adolescent and risky procedure and is often used as a “last-resort” treatment (Hoyle, 2012). Often, the government agencies that monitor the trials only grant gene therapy to diseases that affect more than one percent of the population with treatments that are ineffective or costly (Panno, 2005).…

    It tries to protect you from the cancer cells that destroy your DNA or RNA. Only thing is if the cancer cells don’t divide on time, they die. Chemotherapy is most effective at killing cells that are rapidly dividing. Unfortunately, chemotherapy does not know the difference between cancer cells and normal cells. The cancer cell will turn back into normal cell but it has some side effects as well- Hair…

    With the developed technology and the phylogenetic tree method, scientists are now able to investigate genes and cells individually to distinguish whether precancerous cells would become invasive cancer cells or not. Like general evolutionary biology notion, they find out cancer cells are also diverse genetically and more likely to survive in the changing environment. Some certain cancer cells may be empowered and adapt. So, they conclude even genetically diverse precancerous cells should be treated because they might hide their ability to spread. It was interesting that there is precancerous cells which does not spread around the body tissues but may become invasive.…

    This manipulation can be used to change organisms to become improved versions of themselves. T-cells are subtypes of white blood cells that exist within our bodies. These cells usually fight against viruses and other bacteria that infect our bodies. However, the major problem is that these T-cells do not fight cancer. Therefore, T-Cell reprogramming was discovered to help our immune system counteract cancer cells that infect our bodies.…

    If or when a cell is able to survive this process, it takes a copy of the DNA the virus implanted, and then stores it in the CRISPR. This information is spread to the other cells. When the virus tries to invade a cell, a protein called cas-9 is activated and it reads the DNA looking for a match to the virus DNA it has in store. Once it finds a match, it targets that section of the DNA and cuts the virus replicating DNA out of the cell. The potential this has to cure human diseases is enormous.…

    ○ Explain the process of microarray In a microarray the mRNA is removed from both the infected and uninfected cell. The mRNA is converted into Complementary DNA (cDNA), which is mixed with chemicals. From there cDNA matches up to the DNA already on the slide by looking at the order of the sequence and uniting the two complementary segments. The color on the slide changes depending on… ○ How are the results from a microarray interpreted? ○ Explain how microarray uses Gene Expression to assess cancer risk ○ How is Differential Gene Expression used in a microarray?…
