The doctor in Gattaca sounds strikingly similar to the voice of an Oxford professor in an article by Aleyne who, “. . . said that creating so-called designer babies could be considered a “moral obligation” as it makes them grow up into “ethically better children.”” Savulescu states that, “Whether we like it or not, the future of humanity is in our hands now. Rather than fearing genetics, we should embrace it. We can do better than chance.”” While it is true that human genome editing has the…
In sequence 2 the protein that was discovered was Presenilin or PSEN. Presenilin helps to process proteins that transmit chemical signals from the cell membrane to the nucleus ( PSEN1 gene ). These genes are used for cell growth and maturation.The protein makes sure that the cells are growing properly and that they are maturing properly as well. Presenilin is also known for its role in processing amyloid precursor protein which is located in the brain and the brain tissue (PSEN1 gene ). Amyloid…
Cell Theory is used to describe cells as the basic building blocks of all living things. All organisms are composed of one or more cells and have an outer layer of a plasma membrane (or cellular membrane), which acts as a barrier that divides the cell from its surrounding environment. The plasma membrane of a cell acts as a physical barrier and regulates the exchange of materials with its surroundings. It is a permeable membrane that surrounds the cytoplasm. The contents held within the plasma…
Mitochondria, LHON The Organelle The most well known function of the mitochondria is to produce energy for the cell. It does this by regulating cell metabolism and respiration. Mitochondria carry out multiple other functions that are extremely important (such as various forms of signaling) The mitochondria also contains DNA which can have a direct effect on some functions of the human body if there is a mutation. ( Mitochondrion.(2016, October 9)) Word count 63 (not including headings or…
DNA DBQ Human genes should not be modified.First of all, the embryos who are unborn can’t give consent to have their genes modified(OI). Also, this may result in possible death for the embryo. Even though it is proven to make these altered kids smarter if they survive, they may not be normal. The national debt of the U.S is trillions of dollars(OI). We could be spending taxpayer money on something that have a higher chance of working. These are some reasons why it’s an awful idea. Even though…
1. a) The three parts of a nucleotide are phosphate, nitrogen-containing base, and the deoxyribose sugar. b) Deoxyribose sugar is the sugar that is found in a nucleotide. c) The nitrogen-containing base is the nucleotide component that contains nitrogen. d) The four nitrogen bases shown in Model 1 are Adenine, Thymine, Guanine, and Cytosine. 2. a) I pointed at a single nucleotide on the ladder model of DNA, on the worksheet. The nucleotide included phosphate, nitrogen-containing base, and…

cloning organisms involves the process of somatic cell nuclear transfer. Which means that the DNA of an organism(called the donor) is extracted from a cell(usually a skin cell of biopsy) and it is inserted into the egg cell of another organism, but of that same species. The egg cell has had its nucleus removed in order for the egg cell to start replicating the DNA of the donor organism. Then the newly created embryo is zapped with electricity so that the cell can start replicating, which is…
Cell biology 1. A cell is eukaryotic because Is generally larger and much more sophisticated than prokaryotic cells due to the presence of a complex series of membranes that divide a typical eukaryotic cell into compartment. Eukaryotic cell has an organized nucleus with a nuclear envelop. Has membrane bound organelles Contain linear DNA molecule that are larger than the (circular) DNA molecules in prokaryotic cells and, in association with proteins, form structures called chromosomes.…
What is a white blood cell? A white blood cell is a cell, which goes around the blood system searching for microbes. There are different types of white blood cells and this is about Neutrophils Granulocyte (also known as Neutrophils). They are the most abundant white blood cells in the body produced by the red marrow. They are responsible for phagocytosis of foreign elements (ex. bacteria), meaning they eat up those particles (unfortunately they die in the process) to defend our body against…
