Technology today now allows us to address the idea of cloning. Cloning is creating an identical genetic copy of an organism or a cell. The process of this is there will be three subjects A, B, and C a body cell will be taken from A, the DNA will be extracted then an egg cell will be taken from B the nucleus removed. The DNA from A is fuse with the egg cell from B the fused cell develops into an embryo when it is placed in C the surrogate and then the clone is of subject A. To get to cloning…
The purpose of Activity 1 of this lab is to understand how cell transportation works, The purpose of the second part is to explore semipermeable membranes. The purpose of Activity 3 is to explore how the size of a cell affects cell transportation. Background All cells are surrounded by a barrier called the cell membrane. It regulates what enters and leaves the cell, and also protects and supports the cell. Cell membranes are semipermeable, meaning it doesn’t allow all molecules to pass through…
Ribosomes appear as dark granules in the cytoplasm. Measured by rule: approximately 1 mm actual size 10 nm (image size)/(actual size)= Change 1 mm to nanometres. 1mm=1000000 nm 1000000nm/10nm= 100,000 Data based questions a. Nuclear pores. b. The pores transport molecules between nucleus and cytoplasm. This is the outer nuclear membrane because the phosphate heads (dark line) are visible and they are the ones which face water on either sides.…
efficiently change the internal organization of the cell, and capture organelles through the cytosol. Intermediate filaments are made up of the protein keratin. Their primary function is to strengthen the internal structure of a cell. Microfilaments are the smallest among the three cytoskeletal filaments. They consist of protein actin. Microfilaments are dynamic structures that can rapidly disassemble or assemble themselves, and thus microfilaments enable the cell to move efficiently. Cilia and…
In Aristotle’s view, everything in this world can be categorized. Living beings include plants and animal. The plant has nutritive soul and the animal process both nutritive soul and perceptive soul. If we discuss animal further, we can divide animal into rational animal, which is human, and non-rational animal. The essential feature of “being an animal” is perception. From the Aristotle Introductory Reading: “413b2: What makes something an animal is primarily perception.” Perception is…
Genetic Engineering is the modification of an organism 's genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. With this new, rapidly growing, technology we are now able to do things that we once thought were impossible. In Ethics and the New Genetics, the Dalai Lama addresses problems that we need to consider as we continue to explore this microscopic world that we have…

In the case of a missing limb, the scientists would take stem cells from the patient and us it for the base of the new limb. If Humans mastered cloning then they could use that technology and the patient’s stem cells to construct a new arm, leg, ear, or whatever was missing without worrying too much about the patient’s body rejecting the foreign limb. In the case of organs the process would…
The mitochondria is one of the most interesting components of the eukaryotic cell. Endosymbiosis is the term modern scientists use for how the mitochondria came to be. Symbiosis translates from Greek to English as “living” “together.” Constrantin Mereschkowsky, known as the founding father of the theory of endosymbiosis, was one of people who started the concept of endosymbiosis, although he had called it “symbiogenesis,” defining it as: “the origin of organisms through the combination and…
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…
