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…

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…

ichael explains his case in a creative way. He has Down syndrome when the chromosomes came to make him, a normal chromosome broke, the broken piece moved and struck onto another chromosome.Its called spontaneous translocation.No one knows why this happens or how to prevent it. He starts to talk like how he is like everyone else. All he does is learns things a different way. It takes him longer to process information and form his thoughts and communicate with others. He gets frustrated when…

That is how I think of Biology, the smallest thing like a cell can do some impressive things. Biology being the study of life gives us an endless reality of changing and learning the ways of life. Taking the smallest thing like a cell has the power to change everything. The cell’s power can be used for good or for bad. Cells have the capabilities to cure the most invasive diseases. Us humans, for instance, is such a complex organism cell growing, reproducing and then dying and starting all over…

Comparison chart Replication Transcription Purpose The purpose of replication is to conserve the entire genome for next generation. The purpose of transcription is to make RNA copies of individual genes that the cell can use in the biochemistry. Definition DNA replication is the replication of a strand of DNA into two daughter strands, each daughter strand contains half of the original DNA double helix. Uses the genes as templates to produce several functional forms of RNA Products One strand…

The ethics of gene manipulation proposes a rather complex debate because of opposing religious/individual takes on this issue. My position on this issue is “in-between” because this could be a fantastic advancement at rescuing a family from a harmful genetic disease passing on and advances in genetic engineering have and still could enable an abundance of people with infertility problems to start a family. Although, the negative impacts of gene manipulation remain vital, it violates a child’s…
