Why we Shoudl not Promote Dna Testing
By: Lorraine Nyc
I understand that science in general has led to a better quality of living in some regards, but it has also changed humanity to a degree that exceeds being beneficial. We must not forget that for every action there is a reaction. DNA studies may...
Is human cloning too close for comfort?
By: Amy Rosenburg
Many people believe cloning another human being would have extremely dangerous outcomes. "Who would want another copy of themselves?" these people ask. These people may also see cloning as something more out of a science fiction movie that as an idea that may become...
Gene expression explained
By: Jeffrey Graf
Gene expression refers to the control the cell has over when and how much protein is created from a particular gene. Every cell nucleus contains a complete copy of the organism's DNA, but only a small portion of the total genes are expressed, or translated...
The process of DNA replication explained
By: Jeffrey Graf
The nucleus of a cell contains the chromosomal DNA for an organism. Since each cell in an organism must have a complete compliment of DNA, all of the DNA in the nucleus must be replicated before a cell divides. Because the organization of chromosomal DNA...
Is genetic engineering ethical?
By: Chris Martin - 452908
Technology has greatly shaped the world in which we now live. The technological advancements seen over the past twenty years have been bountiful and seemingly endless in all aspects of life. Increasingly prominent are the advancements that have been made in science, specifically in genetic...
How scientists use genetic engineering
By: Rohit Kulkarni
Genetic Engineering or recombinant DNA technology is a method of artificially manipulating the genes of an organism. A gene is basically a segment of the DNA which specifies the protein sequence. Protein sequences are what give the DNA its characteristics. Recombinant technology uses methods like...
Good Dna Research
By: Larry Swinford
The way some people picture and describe DNA reasearch reminds me of those cheesy old black and white monster movies (and some early film with color) where the "radiation" mutation scares were sometimes hilarious, without intending to be. People were running around and screaming about...
A look at how gene regulation controls the rate of gene expression
By: Alicia M Prater PhD
Every living creature has within its cells a genetic code made of nucleotides on a sugar-phosphate backbone nucleic acid. There are two types of nucleic acids ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). In most living things, the genetic material is DNA. For the sake...
How scientists create recombinant DNA
By: Alicia M Prater PhD
Recombinant DNA is the result of combining DNA sequences that normally do not occur together. The first report of recombinant DNA technology was a 1974 paper by Cohen and Boyer. The 1978 Nobel Prize in Medicine went to the group (Arber, Nathans, and Smith) that...
Is gene silencing ethical?
By: Alicia M Prater PhD
Gene silencing is a natural process utilized by researchers to understand the role of particular genes in disease. It is used medically to cure and treat disease. How can it not be ethical?Let's look at what is involved in the process known as gene...
