DNA DBQ Human genes should not be modified.First of all, the embryos who are unborn can’t give consent to have their genes modified(OI). Also, this may result in possible death for the embryo. Even though it is proven to make these altered kids smarter if they survive, they may not be normal. The national debt of the U.S is trillions of dollars(OI). We could be spending taxpayer money on something that have a higher chance of working. These are some reasons why it’s an awful idea. Even though…

1. a) The three parts of a nucleotide are phosphate, nitrogen-containing base, and the deoxyribose sugar. b) Deoxyribose sugar is the sugar that is found in a nucleotide. c) The nitrogen-containing base is the nucleotide component that contains nitrogen. d) The four nitrogen bases shown in Model 1 are Adenine, Thymine, Guanine, and Cytosine. 2. a) I pointed at a single nucleotide on the ladder model of DNA, on the worksheet. The nucleotide included phosphate, nitrogen-containing base, and…

cloning organisms involves the process of somatic cell nuclear transfer. Which means that the DNA of an organism(called the donor) is extracted from a cell(usually a skin cell of biopsy) and it is inserted into the egg cell of another organism, but of that same species. The egg cell has had its nucleus removed in order for the egg cell to start replicating the DNA of the donor organism. Then the newly created embryo is zapped with electricity so that the cell can start replicating, which is…

Cell biology 1. A cell is eukaryotic because  Is generally larger and much more sophisticated than prokaryotic cells due to the presence of a complex series of membranes that divide a typical eukaryotic cell into compartment.  Eukaryotic cell has an organized nucleus with a nuclear envelop.  Has membrane bound organelles  Contain linear DNA molecule that are larger than the (circular) DNA molecules in prokaryotic cells and, in association with proteins, form structures called chromosomes.…

What is a white blood cell? A white blood cell is a cell, which goes around the blood system searching for microbes. There are different types of white blood cells and this is about Neutrophils Granulocyte (also known as Neutrophils). They are the most abundant white blood cells in the body produced by the red marrow. They are responsible for phagocytosis of foreign elements (ex. bacteria), meaning they eat up those particles (unfortunately they die in the process) to defend our body against…

The notion that there are genetic causes of speech, hearing, and voice disorders is relatively new, and studies in this field are beguiling to emerge as time passes. The article Exploring genetic and environmental effects in dysphonia: a twin study attempts to "explore the existence of genetic effects as well as the interaction between potential genetic effects and a voice-demanding occupation on dysphonia.” As a scientific study, the article first provides evidence that the research can be…

articlekey=4402 The mitochondrial inheritance is caused by mutations in the mitochondrial DNA that is maternally inherited from the mother. The Mitochondria is structure of organelles, that is found in the cells located in the cytoplasm outside the nucleus. The mitochondria job is to manufacture energy in each of the cells and throughout the body https://www.medicinenet.com/script/main/art.asp?articlekey=4402 .The process of ATP production depends on the number of biochemical reactions that…

23andMe is advertised to the public as a beneficial not only to help us as people get closer to our ancestral past, which is somewhat pointless due to the fact we have no true meaningful connections to these pasts. But to also help us grasp a better understanding of what lies within us health wise, whether it be a genetic trait such eye color or ones risk for developing a type of defect. The company’s mission statement says it all in fact, “We are a mission-driven company with big dreams of…

Paracrine Signaling Signals that act locally between cells that are close together are called paracrine signals. Paracrine signals move by diffusion through the extracellular matrix. These types of signals usually elicit quick responses that last only a short amount of time. In order to keep the response localized, paracrine ligand molecules are normally quickly degraded by enzymes or removed by neighboring cells. Removing the signals will reestablish the concentration gradient for the signal,…
