Endosymbiotic Theory Sarah Munn Cell Structure 4th period Endosymbiotic theory where to begin with this theory that has such an impact on a lot. Let us start with what this theory for the readers that may not know or just might need a refresher. The Endosymbiotic Theory states that mitochondria and chloroplasts (organelles that provide energy for eukaryotic cells using photosynthesis and cellular respiration respectively) were once independent prokaryotic cells themselves

inherited from our parents. Therefore what makes us who we are? Many people would believe that we learn because of what we experience in life and others would argue that we are predestined because of our heredity. Both parties have piled up plenty of evidence to support their theory. Genes are the basis of our lives and as we grow the environment influences how our genes react and program our brains. “Genes are designed to take their cues from nurture. The more we lift the lid on the genome, the more

GMOS GMOs, or genetically modified organisms, have been around for about 40 years now. A genetically modified organism is a plant or animal whose genes or “DNA” have been modified in such a way that the product is not naturally found in nature or through natural cross-breeding. Traditionally, the genes with the desired characteristic are introduced to the genes of the plant/animal that is being genetically modified. This results in a plant that is very similar to the original, but contains varying

Down syndrome occurs when someone has has a full or partial copy of chromosome 21 the cause of down syndrome is called nondisjunction, nondisjunction is what happens when chromosomes fail to separate properly thus having an extra strand of dna on trisome 21, down syndrome is also known as trisomy 21. Down syndrome affects every 1 in 691 babies in america which make it the most common chromosomal disorder in the world. yet despite it being the most common in the world there is still no cure for down

Monday. Researchers at the Center for Research in Environmental Epidemiology (CREAL) in Barcelona, and the Research Institute Hospital del Mar studied changes in indicators of mutagenicity - permanent mutation of the DNA - among a group of swimmers in a chlorinated pool. "The evidence of genotoxic effects were observed in 49 healthy adults after swimming for 40 minutes in a chlorinated pool," CREAL said in a statement Monday. The researchers found indicators increased risk of cancer in healthy subjects

Biotechnology Insulin crystals Biotechnology is the use of living systems and organisms to develop or make useful products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use" (UN Convention on Biological Diversity).[1] Depending on the tools and applications, it often overlaps with the (related) fields of bioengineering and biomedical engineering. For thousands of years, humankind

have debated about nature vs. nurture and whether, which one can be scientifically proven to provide evidence about the facts; from human behavior and identical twins separated at birth. Looking through the points of nature argues that put made by their parents, scientifically speaking, every trait and gene is genetically passed down through our parents. On another note, nurture provides us with evidence about our personalities and how they are sculpted through how and where we grew up (Scott, 2008)

These cells have half of the genetic information from the original parental diploid cell (Pearson School 2011). Twenty-three chromosomes are present in each cell. Once the sperm and the egg meet, Meiosis begins. This process of splitting cells and DNA replication can result in genetic information to be transferred, deleted, or relocated on accident. Twenty-three chromosomes from the father and twenty-three chromosomes from the mother combined, resulting in forty-six chromosomes in each cell. A congenital
