Ethics Week 4 Embryonic stem cell research poses an ethical dilemma. In the case of embryonic stem cell research, it is impossible to respect both moral principles. To obtain embryonic stem cells, the early embryo has to be destroyed. This means destroying a potential human life. But embryonic stem cell research could lead to the discovery of new medical treatments that would alleviate the suffering of many people.
Or each chromosome of a pair can be individually picked. 16. Explain two ways in which children can have different chromosomes (gene variation) than their mother or father. Random separation of chromosomes (law of segregation) when forming sperm/ova during anaphase I, crossing over of some genes to the homologous chromosomes during prophase I, and mutation during S
Having two sets of chromosomes is known as (2n) _______diploid___________. ANSWER: 6. Eggs and sperm are _______haploid_________ (n). ANSWER: Next Give one characteristic of each of the following phases of Meiosis I. Prophase I: During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis Metaphase I: Bivalents, each composed of two chromosomes align at the metaphase plate Anaphase I: Each of the daughter cells is now haploid Telophase I: Nuclear envelopes may reform 7. Does the S phase (DNA replication) occur after Meiosis 1?
• Environmental influences are crucial for almost every complex trait, with each child as well as each culture experiencing different environments. Chromosomal and Genetic Abnormalities: • Every normal human cell, except for sperm and egg cells, has 23 pairs of chromosomes for a total of 46 chromosomes. Sperm and egg cells have only one of each pair of chromosomes for a total of 23. Each chromosome contains hundreds to thousands of genes. • The sex chromosomes are one of the 23 pairs of chromosomes.
Doctors make no use of the embryo. If embryonic stem cell research was legal the discarded embryo could be used to save lives. Although the life of the embryo not continued its cells can be used to help others live longer and healthier. It could be considered the faith of the embryo to help mankind in finding and creating the cure for many diseases. Politicians and other people fighting against embryonic stem cell research are saying that it would cost too much money to fund.
Discuss ethical considerations in research into genetic influences on behavior INTRO: Many ethical concerns arise from genetic research – there are no exact answers to these questions, but rather point of views that are poorly or well defended. In many countries, certain genetic tests are considered normal and appropriate during pregnancy. This is particularly useful as it has prevented many potential problems. For instance, a test with Phenylketunoria can be conducted, it the result is positive, then the parents can be prepared to follow a special diet the baby needs from birth to prevent any brain damage. It is also possible to test for Huntington’s disease, but there is no treatment for the disease.
These opinions are varied and usually supported within certain societies or organisations. Ethics occur every day in everything we do. This is shown in a way that people do things in different ways and for different reasons. One of the main areas of genetic engineering is genetic manipulation of human cells, known as Human Cell Therapy. Around 40 years ago two scientists James Watson and Francis Crick (1980) of the Medical Research Council discovered that there were more than 3000 medical disorders that could develop within the human body as a result of errors in the individuals DNA (Medical Discoveries, Genetic Engineering).
This discipline is one of the most important sciences from the point of the description of any living system because the inception of each living organism is based on genetic information that determines the anatomic structure of each organism and on substances that play an important role in biochemical and physiological processes. Genetic information is also crucial for reproduction because genetic information get passed from parents to their offspring. Findings of molecular genetics are used in various fields, such as in agriculture in the process of plant breeding, now modern techniques that were developed on the basis of the knowledge of molecular genetics are used to produce genetically modified plants that carry advantageous traits; in medicine to research genetic diseases and find an appropriate treatment; or in forensic science, modern methods can help to solve crimes due to the determination of the genetic information in a tissue sample and compare it to genetic information of the criminal. My primary purpose is to mention some of key developments in molecular genetics in the past and present that have had a relevant impact on the society, and outline possible future directions of these developments. First, I will focus on developments that influenced recent and current research; second, I will mention some recent and current developments that are perhaps most important for the society now; finally, I will try to adumbrate some future directions of the findings in molecular genetics.
The child could have been perfectly healthy, but the test showed traces of a disease in their gene pool. Screenings can also show if a baby has a certain eye or hair color. The screening can cost thousands of dollars, to not even receive a result. When talking about genetic screening being either good or bad, it all comes down to your morals and values. Do you think its okay that people will get these screenings done so they can terminate a child who isn't good enough?
Cloning and Its Benefits Cloning is making a copy of life products such as animal, plants, or even human races. Some people oppose cloning idea because they think making a copy of life products is contradictory with the principle of every religion in the world. Many people also think that cloning is an immoral thing to do because cloning modifies people’s life that “God” has given to us. In other words, cloning is playing “God”. “In a Zogby America poll of 1,201 adults, 58.5% said they believe cloning is immoral and wrong compared with 35.6% who said they think cloning would
be extraordinary way to cure disease and provide transplants”(http://www.organicconsumers.org).
