Cell type

nucleolus is a darker staining region of the nucleus. It is non-membrane bound structure composed of ribonucleic acids (RNA) and proteins. It makes ribosomes inside the nucleus and contains all the DNA of the cell. It is also used for cellular reproduction and it is often referred to as the brain of the cell as it controls what goes on. Golgi apparatus A group of fluid-filled flattened membrane bound sacs located close to the nucleus. Vesicles are regularly seen at the sacs' edges. It is…

When you hear term "happiness", you think of happy thoughts or events in the past you have been through that has caused the feeling of happiness to occur. Although it is just a feeling, a mere sensation you feel throughout your body, it has the amount of force and meaning to push anybody beyond their limits. The definition of happiness can be explained by a mental state or emotion you feel after pleasant thoughts and/or memories intervene from contentment to joy. Sure, you can live on with this…

The issue that I am going to write my paper over is about genetically engineered embryos and whether or not further research should be done to allow the altering of an unborn fetus. My first topic that came to my mind when I heard about this assignment was actually abortion. Then we were shown a list of banned topics and abortion was number one on the list which was disappointing. Later when we went to the library to search for our topics, I ran across an article that interested me. It was about…

about being on an organ transplant waiting list for decades, waiting for their inevitable death. Human cloning has allowed us to grow organs, by using skin cells and converting them to stem cells. The nucleus of these stem cells of skin are then replaced into the nucleus and create what is known as a blastocyst, a bundle of hundreds of cells whose purpose is to specialize growing a specific body part, such as an ear. (Knapton). Not only can this help people who are in life-threatening…

Mendelian inheritance is centered around three laws discovered by Gregor Mendel. First is the law of segregation which states that during the formation of gamete the two allele pairs separate randomly. The second law is independent assortment which states during gamete formation each pair of the allele will segregate independently of the rest of the pairs of the chromosomes. The third law is the law of dominance which is that alleles can be dominant or recessive with the expression of the…

modification. Later, logos is shown through the statistic Hayes gives about forty countries’ genetic modification regulations. Hayes’ strong points consist of exposing Green’s equivocation of the words “genetic technologies” and distinguishing what the two types of genetic technologies…

scientific process called the somatic cell nuclear transfer or SCNT. During this process, scientists remove the chromosomes from the egg cell and replace them with the nucleus of a somatic cell which contains two sets of chromosomes. Since the nucleus of the somatic cell comes from a human who already displays genetic variation from their mother and father, the clone will receive both of their sets of chromosomes from one cell, and not from both the egg and sperm cells (“What is Cloning?” 1).…

The Cell Membrane is one of the most important parts of the cell. If not for the cell membrane it would be extremely easy for things to invade the cell; this is because on of the cell membranes job is to control what come in and out of the cell (i.e. ions, viruses, etc). Also the cell membrane is what helps hold the cell and all of its organelles Endoplasmic Reticulum (AKA the ER), smooth and rough whats the difference? The smooth ER does not have any ribosomes while the rough ER is covered in…

chanted Captain Xerox at headquarters, and with that our micro-V96 craft was propelled towards the cell membrane for the first leg of our journey to investigate the process of Protein Synthesis in a eukaryotic animal cell. The cell membrane is a delicate wall of phospholipid molecules, consisting of hydrophilic heads and hydrophobic tails that swayed and looked like a mosaic. Our craft could not enter the cell directly through the semi-permeable membrane as it consisted of a negatively charged…

Respiration Rate Analysis on Goldfish While Being Exposed to Varying Water Temperatures Avarie Wideman, Bronwyn Edgell, Brooke Farrell, Shannon Porter & Emma Milne 1 Uxbridge Secondary School, Uxbridge, Canada ________________________________________ Results After completing the goldfish respiration experiment we were left with an abundance of data that has lead us to these results. Through the experiment we have discovered that the goldfish's respiration is affected when exposed to extreme…
