This Cartoon pertains to the biological concept of evolution. Over time species adapt to better fit their enviornment. This cartoon is humorous because it depicts the events of millions of years in one instance.

Blog 4: Biology Song!
Verse:
There are just four bases in DNA.
There is G and T, and there’s C and A.
And their sequence in genes
Forms our guts, lungs, and spleens
From our genome after all.
Chorus:
It’s your genome after all,
It’s our genome after all,
It’s our genome after all,
We’ve great gobs of genes.
Verse:
If your ACA turns to ACT
There’s a world [...]

This cartoon shows a biologist who discovers a talking amoeba. The talking amoeba first says an addition problem, then a subtraction problem and a division problem. The bioligist then quickly smashes it with a hammer and says “I wanted to get it before it multiplied”. This joke refers to the division of amoebas. The basic result [...]

The very strange evolutionary classification of Ferrets
Nicole Steck
Ferrets are animals that have very complex taxonomical and evolutionary histories. Black-footed ferrets, Mustela nigripes, are an endangered, predatory species that live in prairie areas. M. nigripes are evolved from weasel-like ancestors. The first ferrets were Mustela stromeri, which most likely evolved M. putorius (European polecat) and M. [...]

Evolution is a a gradual change in a population over an extended period of time. Evolution does not simply occur in just one individual but is passed on over many generations. On the molecular level evolution is a change in the frequency of alleles within a gene pool from one generation to the next. A [...]

Biological measures have long been used to try to control pests in crops. Wasps, frogs, and ladybeetles have all been used to control pest outbreaks in crops. Biopesticides is simply taking this one step further. Biopesticides are naturally occuring fungi, bacteria, or viruses that would be applied in much the same way as chemical pesticides. [...]

Evolution is essentially natures form of an arms race. It is a competition to see which species can adapt the best to their environment. Which predator can develop the most efficient techniques of catching prey, which prey can come up with the best defense. It is interesting to note, then, that for the first time [...]

One of the biggest contributors to the theory of evolution was Charles Darwin. Darwin used countless research to help prove countless doubters wrong about the theory of evolution. Although the theory already existed before Darwin, he greatly helped gain widespread acceptance and made believers out of many. Darwin introduced the idea of natural selection. [...]

Gene Flow
            There are three basic mechanisms of evolution: natural selection, genetic drift, and gene flow.  Gene flow is the one that I am going to focus on in this blog.  Another name for gene flow is gene migration because the genes move from one population to another.  They tend to stay within the population [...]

Asthma is a chronic disease that affects the bronchioles. Asthma is genetic, which means that it is inherited, and increases ones tendency to develop asthma.  During an asthma attack the bronchioles become narrow, which makes it difficult for air to pass through them. The muscles outside the bronchioles tighten, causing the mucus membranes to produce [...]

            A genetic mutation can either be detrimental or beneficial to an organism. It occurs during the process of DNA replication, where the DNA replicates itself so that a cell’s daughter cell receives the same set of genetic instructions that the parent has. Errors in DNA replication are caused by exposure to radiation or harmful [...]

Disease can be caused by either environmental or genetic factors; but typically the development of disease arises from a combination of the two.   A genetic disorder is caused by abnormalities in genetic material.  There are four subcategories of genetic disorder including: single gene, multifactorial, chromosomal, and mitochondrial. 
                There are 6,000 single gene disorders, examples [...]

Autosomal recessive inheritance is a term which refers to the inheritance of recessive traits. Recessive traits are, in terms of genetics, the traits that do not occur if another trait is present. Blue eye color is an example of a recessive trait: a person can only have blue eyes if both parents carry the gene [...]

Genetics is the science of heredity and variation in living organisms.  Genetics relates to everyone.  All organisms in some way look similar to their parents.  Some times these acquired traits cannot be seen through physical means.  Personally, the traits that I have obtained from my parents are pretty well mixed between the two.  For example [...]

My genetics posting is on Ehlers-Danlos Syndrome Type 4, the Vascular Type.  Ehlers-Danlos is a genetic disorder that results in a defect in collagen synthesis.  The Vascular Type of Ehlers-Danlos is caused by a genetic mutation type III procollagen gene COL3A1.  Found in the early 20th Century by Edward Ehlers and Henri-Alexandre Danlos.  The rate [...]

When parents give birth to a child there is always the fear that their baby may be born with a genetic birth defect. There is no way to be sure that your baby will be born healthy and most babies with congenital defects are born to healthy parents. Birth defects are abnormalities in structure, function [...]

Salt Cedar, or Tamarisk, is an invasive species that has taken over the riverbanks in many areas of the midwest. They can live in areas with salinity up to 15,000 ppm. The main problem with Salt Cedar is its disruption of the natural aquatic systems. Their roots are deep enough to penetrate into the water [...]

 
On July 23, 2006 Kerry Richardson gave birth to premature twin boys Kaydon and Layton Richardson. Kerry says her twin boys were, “practically the same color.” But over some time the twins have started to difference from each other in a unsuspected way. Kaydon(on the left) is black (darker) like Kerry, while Layton(on the right) [...]

Nearly 10 million men- 7% of the overall male population and .4% of women suffer from a non-life threatening disorder that affects their life on a daily basis: colorblindness. Colorblindness does not always mean that persons affected only see in black and white- in fact the most common form of color blindness prevents those affected [...]

            Eye color is something that a lot of people have a hard understanding.  They do not see how two parents with the same color eyes can have a child with a different color eye.  My parents and sister both have hazel colored eyes but I have blue eyes.  Some eye genes are more dominant [...]

      A topic that really interests me dealing with genetics is genetic testing. Specifically genetic testing for downs syndrome in fetuses. During conception a baby is supposed to inherit 23 genes from both mother and father. When a child has Down syndrome it means that during conception the child inherited an extra chromosome giving [...]

For thousands of years people have been struggling to produce enough food to feed themselves. Thanks to recent advances, however, the problem is not that we do not have enough food, it is its distribution. The most recent of these advances is the genetic modification of crops. We can now grow, among many other things, corn [...]

Deoxyribonucleic acid (DNA) is one of the centerpieces of genetics.  DNA is the basic structure of all living organisms in the sense that it contains instructions for the construction of other components of cells such as RNA which is why it is compared to blueprints or a recipe. The main role of DNA is long [...]

This “lucky bamboo”, or Draceana sanderana, will serve as an example of photosynthesis.  Although bamboo doesn’t require a lot of sunlight to survive, photosynthesis is still occuring.

Termites have a long history of destroying homes and eating through wood products that we would rather they didn’t but it is just what they do. My grandmother’s house has been infested with termites for a long time and terminx missed it for the last 7 years (Don’t ever use them)! “Termites have a healthy [...]
