Biology Semester 1 Research Project Cellular Process Meagan Baggett 4th Period The endosymbiotic theory explains how eukaryotic cells may have evolved from prokaryotic cells. Symbiosis is a close relationship between two different organisms. The discovery of the endosymbiotic theory took hundreds of years to be considered as real and was eventually it was finalized. The endosymbiotic theory is believed to be first introduced and described by Andreas Schimper in 1883. Schimper was a

and differences between plant (agapanthus) cells and animal (human cheek) cells to be examined. The shapes shown in the results were these two types of cells. The cell that was dyed pink was a human cheek cell, and the regular-shaped cell was an agapanthus cell. The basic structure of an agapanthus cell and cheek cell could easily be seen. It is obvious that the individual cells were more detailed when a higher magnification was used to observe the cell samples. From the highest magnification of

your child has a disease such as SCID can be hard. Virtue Ethics is a theory of morality that makes virtue the central concern. When you find out your child has a disorder and the doctors tells you a cure but it may make your child form similar T-cells like leukemia, you have to way out the options. In the case of virtue ethics, if you could put yourself in your child’s shoes and ask yourself “What should I be”. If I were my child would I want to be in the hospital, constantly testing new cures or

The Great Danger of Genetic Modification in Human Beings. According to Ronald Greene in ‘Building Baby from the Genes Up’, “National Institute of Health has come up with a program to build machines with the ability to detect genetic letters in human’s genome.” (Greene, 496) The researchers believe that this will lead to being able to see DNA sequences which could later result in a particular disease or illness in a person. According to Ronald Greene in ‘Building Baby from the Genes Up’, “National

The Solutions to Designer Babies Perfection in terms of procreating was once a sky limit that was unreachable. In the pursuit of procreating the most perfect children, today’s society has proven this limit to be attainable. The issue of “designer babies” has shaken not only are nation’s values on the introduction of new children into the world, but also our unity as a society on this subject. Designer babies could arise problems in diversity around the world, the outnumbering of women in some countries

(present in some cells). They are different because Plant cells have centrioles or intermediate filaments. They also have a more square shape and contain chloroplasts. This allows plant cells produce their own food or energy. Animal cells must obtain food from a source outside of the body. Plants have a cell wall that is made up of fibrils of cellulose. Plants have only one big vacuole, but animals have many small vacuoles. Plants also contain plastids while it is absent in animal cells. Animals have

molecular biology? What will you explore in this unit? Molecular biology is the study of the molecular basis of genes and gene expression (molecular genetics). We will explore the following: -the structure of DNA -how it replicates -how it controls the cell by directing RNA and protein synthesis -how it can change -viruses that infect bacteria, animals, and plants -bacterial genetics 2. Who are Hershey and Chase? What were they trying to figure out? Why were they trying to figure this out? Alfred Hershey

Humans are born with genetic mutations and malfunctions that lead to life-threatening diseases. Diseases such as cancer and alzheimer’s constantly cause suffering through families. This is why genetic testing and engineering is building up to modifying the genetic coding to the point where these diseases do not exist in the body. Not only that, genetic engineering could possibly get to a point in time in which they modify DNA for pleasing factors such as aesthetics, intelligence, talent, and personality

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

double stranded dna molecule. The bases are matched and edited to match their partner. Each strand acts as a main component for the replication What is the importance of replication? Why do cells replicate their DNA before dividing? They replace their data so the could get rid of the old dna so that the cell may be able to be healthy. Use the clues and words to help you write the vocabulary terms from the chapter in the blanks. You may use a word once or not at all. 3. tip of a chromosome
