DNA repair

Cell Biology Beta cells in pancreatic tissues are described as eukaryotic cells and not prokaryotic, this is because the cell is larger in size and there is a true nucleus present which contains DNA. In prokaryotic cell there isn’t a nucleus and the DNA is free within the cytoplasm. Also Beta cells have many organelles and there is mitochondria present, which in a prokaryotic cell there are fewer organelles and there aren’t any mitochondria present. Beta cells in the pancreatic tissue release…

Currently, there is one procedure widely used to detect mutations that could lead to heredity diseases or genetic diseases harmful to the future child’s health. When a woman wants to be a mother, she can choose in vitro fertilization (IVF) where the eggs of the mother are removed and mixed with sperm in a laboratory ("Fertility Treatment: In Vitro Fertilization (IVF)"). It is during this time embryo selection can occur if the mother wishes. The mother can choose a procedure called…

the lab. Therefore, the organism is the inhibitor of the product in biochemistry and a correlate with its metabolic structure, which can lead to a phenomenon. For example, a proteins purpose and how it can affect the delicate process of developing DNA or DNA replication if one item could be…

that have half the chromosomes of the parent cell. Mitosis and meiosis are similar in a way that they are both ways in which cells reproduce. Mitosis and Meiosis both occur in humans and animals. In both cases (Mitosis and Meiosis), cells copy DNA and make new cells based on the information of parent cells. However, in Mitosis, the cell only divides once and in Meiosis, there are two different cell divisions which are the first and second divisions. In Mitosis, spindle fibers completely…

Breast cancer is a malignant neoplasm that is located within the cells of the breast. Normally, cells divide to grow, repair, and replace other cells. This cell division is controlled by DNA within the nucleus of every cell. However, when cells in the body start to grow out of control, cancer begins. A variety of factors, both genetic and environmental, may disrupt growth of regulatory pathways and result in the development of cancer. Major factors taken into consideration for breast cancer…

conditions, and fighting against a plethora of diseases, but within the last decade a solution to all of our problems has appeared: genetic engineering. Genetic engineering is essentially the manipulation of an organism’s DNA, which is what makes up its genetic structure, to repair damaged parts or introduce new genes to produce beneficial effects such as attaining higher crop yield or curing diseases. Although genetic engineering seems like the ultimate solution, there are some criticisms that…

geneticists understand the past and our ancestors better. Since mtDNA is only inherited through the mother then all mitochondrial lineages are maternal. Thanks to the study of the mitochondrial genome it revealed that all humans carried mitochondrial DNA in their cells that dated back to a single…

Systemic Telomere Length and Aging Telomeres represent essential structure for genome stability, since their role is to protect the extremities of linear chromosomes from degradation and recombination. Furthermore, they also participate in the nuclear architecture, as well as in the meiosis-specific genome recombination and reorganization. Telomere length is the result of the equilibrium between shortening and lengthening mechanisms, and in many different organisms there is a decrease in…

changed. Instilled, of breeding two similar types of creatures or plants together, scientists and engineer can immediately modify the transmitted sequence of the DNA of a species. In altering plants and specific crops for food supply have…

sixth step which is responsible for energy metabolism (Bio Rad 2017). Aside from its role in glycolysis, GAPDH is also known for its evolutionary significance specifically that it has roles in cellular function like nuclear RNA export and DNA replication and repair (Tatton et al. 2001). GAPDH has been found in apoptosis, neurodegenerative disease, and viral pathogens which is part of its biomedical significance (Tatton et al. 2001). In addition, Altenberg and Greulich (2004) claim that genes…
