different kinds of glial cells. Glia cells are like the “glue”, they support the neurons of the Nervous system by holding them together. • Astrocytes- “star shaped”, wraps around the presynaptic terminal of functionally related axons, supports the blood brain barrier, provides nutrients, and repairs scar tissue • Microglia- act as part of the immune system, remove waste material and viruses and fungi from the brain • Oligodendrocyte- forms myelin sheath in the central nervous system cells, won’t repair
to find out if Specimen A is a true animal. True animals are multicellular creatures, though the number of cells can change significantly through different species. All animals and plants are multicellular, but the earth is also made up of single-celled organisms, which are mostly bacteria. Once taking a sample from Specimen A we found that it was a multicellular heterotroph that lacks a cell wall. Heterotroph’s are not able to make their own food and they must get it some other way, generally from
Grow Little Cell Grow! Investigating Neurogenesis Neurogenesis, the production of new nerve cells, has been a revolutionary finding as nerve formation has always been thought to end with adulthood. It has not been until recently that such dogma has been contradicted as research findings report that neurogenesis continues in the hippocampus throughout most of the adult life of mammals and primates (1). Recent correlations have been further made between neurogenesis and depression as the latter
located in side of the cell membrane. There are functions, which the cytoplasm holds that includes being a place to set chemical reactions. There are enzymes inside of the cytoplasm which help to bread won are throwaway waste products the cytoplasm helps the give the cell a structure and shape also helps all the things inside the cell stay in a specific position to help better functioning. Plasma Membrane The plasma membrane control anything that enters or leaves the cell as it acts like a large
getting the gene into the nucleus of the cell and fitting it in its proper place. On top of that problem, the new gene must function properly like a normal cell would. Many genetic disorders are the effect of a malfunction in a gene. Through gene therapy the malfunctioning gene can be replaced by a working version of the gene that carries out its normal cellular functions. To make things even more difficult on scientists, fixing the DNA in a few cells will not be beneficial for the patient.
Victor Frankenstein and His Use of Science Every spring there is a plethora of new animate beings. Creation is a yearly event for most animals. There are countless children born each day. All living beings procreate. Victor Frankenstein was a scientist, and the goal of science is to discover new information, and Victor Frankenstein was simply being a scientist and creating new information. When Victor Frankenstein created his monster, it could be compared to genetic engineering or
the short essay “The Lives of a Cell” by Lewis Thomas it is explained that this is not true. In “The Lives of a Cell” Thomas explains that humans are derived from and made of the same indispensable building blocks as all other life forms teaching the reader that despite their diversity earth’s inhabitants have more than their home planet in common. According to Thomas’ essay there is a good chance that all life on earth was “derived, originally from some single cell, fertilized in a bolt of lightning
Current research methods of transfection, delivering foreign DNA into cells, have capitalized on using non-viral vectors because of the recent advantages researchers have been able to exploit. The process of transfecting cells runs into a number of problems by way of the cell’s own defense mechanisms. Vectors must be able to not only enter the cell past the cell’s membrane but also must be able to make its way into the cell’s nucleus to access the targeted genetic material. The problem with traditional
In 1880s, proposed that the genetic information of a cell would diminish with every cell division. Hans Spemann challenged his idea and in his book entitled “Embryonic Development and Induction” talked about a fantastical cloning experiment which later became a basis for animal cloning. He called it a “nuclear transfer experiment” and suggested that cloning could be carried out by transferring nucleus from a cell into an enucleated – a cell whose nucleus has been removed – egg. John Gurdon, at Oxford
The 3 ways can be summarized as 3 C’s: Cell youth eternity Cybernetics Cryonics So, let’s turn to the first C: Cell youth eternity. Cell youth eternity A. Moral cells are born to live and die. [Cells are like human being, mortal, they are born by other cells and they die.] 1. Cells are born by cell division. a. Cell division is the process by which a cell divides into two or more cells. b. Cell division is like women giving birth to children. 2. Cells die of cell division. [Like women can not give birth
into our lives. The timeline presented by Kenneth Jost of the CQ Researcher suggests we have been discovering and patenting specific genetic discoveries since 1911 with the first patenting being the discovery of adrenaline and reproduction of the cells for the general public. Although we share different genes within our species, there are so many separate genetic markers that create our specific identity as humans. Within the research, we are also finding cures to cancers and diseases that have been
Many people have wondered what it is exactly that makes us...human. What is it that separates us from one another that makes us unique? DNA and Genes is what makes every person up. Everyone is different because of it. Humans are different from each other by their skin color, their facial features, and it’s all due to Deoxyribonucleic Acid. DNA or Deoxyribonucleic Acid is a molecule that contains the genetic instructions that are used in the functioning, the development, and the reproduction that
Bionics and Prosthetics In all of the scientific accomplishments this world has produced, one of the most miraculous is the innovation of prosthetic limbs. From the time of the ancient pyramids man has been able to fashion limbs for those missing them. These practices have been used to better the lives of those injured in accidents and that of wounded veterans. The advancements of these devices has been nothing short of miraculous. These devices started in order for those injured in war to be
descendants from two separate free-living prokaryotic cells that joined together endosymbiotically (Margulis 1991).There has been some debate on the order of these events and the amount of times an organism undergoes an endosymbiotic event to become a functioning eukaryote (Yonas 2009). According to The Shopping Bag hypothesis, there can be multiple endosymbiotic events occurring until the endosymbiont can successfully survive and thrive in the other cells environment (Howe, 2008). Meaning that the larger
Nanotechnology is the study of extremely small things and is used in the fields of chemistry, biology, physics, materials science, and engineering. Nanotechnology is measured on what is called a nanoscale, also known as a nanometer which is one billionth of a meter. The important 3 steps of nanotechnology are “small size, measured in 100s of nanometers or less, unique properties because of the small size, and control the structure and composition on the nm scale in order to control the properties
Modes of Documentary A documentary is a film that makes a claim based on empirical evidence. There are four main ways of making films or documentaries. The modes changed and developed due to technological advancements. Filmmakers also wanted the youth to associate with films instead of books. Expository mode: its sole purpose is to describe or explain the meaning of something; it makes a lot of emphasis on the argumentative logic and verbal commentary. This method involves the use of background music
NHEJ functions in all the types of cells, from bacteria to man, and it carries out various functions such as repair of double stranded DNA breaks, telomere maintenance, and the insertion into the genome of HIV-1 and repetitive sequences. NHEJ seems to function in three main steps: 1) DNA
Could you imagine your parents designing you? Picture your parents being able to go into a room and design you just like that. They could choose what you would look like, be like, and even what abilities you may have. It sounds crazy, but science is advancing and soon this will be possible, that is, if we allow it. A designer baby is a child who is genetically modified for the purpose of removing any defects that are genetically linked, and/or to select certain genes that appeal to the parents.
clinics are; Increase mitochondrial density to give you more energy, reduce inflammation, boost metabolism, combat oxidative stress, improve fertility, improve learning and memory ability, prevents the development of osteoarthritis, protects nerve cells from the damaging effects of Alzheimer’s disease, improved mental function, and lowers LDL cholesterol levels (Asprey) (Murray, N.D.). We could go on and on. Does this smack of slightly, “too good to be true”? Pyrroloquinoline Quinone (Figure 1, PQQ)
Statistics Statistics can be defined as the scientific study of numerical data based on variation in nature. It deals with the collection, compilation, presentation, analysis and interpretation of numerical data. Biometry Biometry is concerned with the application of statistical methods to the solution of biological problems. Population In statistics we concentrate on the collection of values of the characteristic, or record of a qualitative trait, evaluated for each unit in the population. We
