Deoxyribonucleic Acid is the molecule within human cells that holds all our genetic material (Genetics Home Reference, 2017). DNA can be found in all cells of the body except red blood cells and can be collected from hair follicles, blood, skin, bodily fluids, bone marrow, tissues etc (GHR, 2017). In criminal cases, DNA is used as evidence to prove whether a person was connected with a crime. If a person’s DNA is found at a crime scene, they become a suspect in an investigation. The use of DNA…

pathway is a chain of proteins in the cell that relays an extracellular signal from the Ras protein to the DNA in the nucleus of the cell. This pathway consists of multiple phosphorylations as MAPKKK phosphorylates and activates MAPKK which then phosphorylates and activates MAPK. At the end of this cascade, MAPK phosphorylates various effector proteins (Alberts, 557). This signaling pathway plays an important role in cells as it results in complex changes in cell decisions and behaviors such…

is the cell theory significant (don’t just state the tenets, explain what it means and why it is a theory)? The cell theory is significant because of it’s three basic ideals or principles. The first is that all organisms are made from cells. This means that cells are the building blocks of life and technically, all of life is connected and related to each other by this tenet. In addition, by researching and examine one type of cell, the results can be assumed for all similar types of cell. The…

Human Cloning is the manufacturing of a group of genetically identical cells or organisms, all come from a single individual. The members of a clone have the same characteristics, except where alternation and environmentally caused developmental variation to have occurred. Cloning should be allowed in society because of its significant advantages. Genetic cloning is done to create a necessary gene from DNA to establish certain characteristics. Although this scientific evolution has a lot of…

which is the production of a cell or organism that is genetically identical to the parent. Two examples of things that can be cloned are genes and animals. For genes, a gene is taken from one organism and enters a carrier called a vector, which can be bacteria, yeast cells, viruses, or plasmids. The vector is then placed in laboratory conditions which makes it multiply, resulting in the gene being copied many times over, or cloned. For animals, a mature somatic cell is taken from the animal…

To begin with, opponents will claim that people are against the cloning process by saying it is unethical and immoral due to how it controls the lives of animals and its level of involvement with animals reproductive systems. According to the website article “Ethics”, several religions, such as Christians, Jews, Muslims, Hindus, and Buddhists, believe cloning is unethical due to how similar it is to “playing God” as well as the “greater level of involvement and interference with animals’…

“The glue is not one thing; it is a variety of different molecules that connect and lie between our cells” (123). This glue and molecular structure gives each cell and tissue their distinct functions. What makes many different body parts different is how the materials like cells and tissues are arranged and attached to each other, like the eye and leg. This indicates that every tissue alignment is different in it’s own way and can be identified…

English scientist credited most famously for the creation of Hooke’s Law (a principle of physics that states that the force needed to extend or compress a spring by some distance is proportional to that distance) in 1660 and the discovery of plant cells using a compound microscope in 1663. The compound microscope uses two or more lenses, which are connected by a hollow tube. The top lens (called the eyepiece) is the one that people look through, and the bottom lens is called the objective lens.…

“Human cloning is coming,” as Mike Pence once said. Cloning is a technological advancement that is making its way toward our era. It has already been established in 1997 through Dolly the sheep, the first cloned living organism by taking a cell and infusing it with electricity to create an exact replica. After this significant scientific breakthrough, the big question asked now is how much farther can we take cloning to another matter like even human cloning? Human cloning is one majorily entire…

deliver the DNA, were developed including viruses, plasmids, and minicircle DNA. These vectors are engineered to contain the therapeutic genes. Viral vectors hold the advantage of a higher transfection profile as well as the ability to target certain cells. However, viral vectors are limited by the amount of genes they can carry, in vivo immune response, and safety concerns. Most gene therapy cases have employed viral vectors despite their drawbacks. On the other hand, plasmids can carry larger…
