Viral Infection Host Cell
851 wordsIt all started with a little tickling in my throat. I forged ahead, knowing all too well what that feeling meant, I was getting sick. I convinced myself to just not think about it and it would just go away. This whole time there was an army of alien species amassing in my bloodstream and older cells. They are horrifyingly ugly, like something straight out of H. R. Geiger's imagination. They writhe and twitch while they are on the hunt for one of your precious body cells. One can almost imagine t...

United States Constitution Life Begins At Conception
1,246 wordsAbortion is defined as the termination of a pregnancy before the fetus is capable of independent life. Abortions must be conducted before the end of six months or the fetus will leave the womb and it would be considered premature birth. If the fetus weighs less than 18 ounces or is less than 20 weeks into pregnancy, it is usually considered an abortion. There are two types of abortions. One is spontaneous and the other is induced. Spontaneous abortions are known y another name, miscarriages. The...

The Human Genome Project
727 wordsA genome is all the DNA in an organism, including its genes. Genes carry information for making all the proteins required by all organisms. These proteins determine, among other things, how the organism looks, acts, processes and fights infections. DNA is made up of four similar chemicals (bases, adenine , Thymine
, cytosine , and guanine ) that are repeated millions or billions of times throughout a genome. The human genome has three billion base pairs. The order of these base pairs...

Takes Place 1 N
858 wordsAlthough Bryophytes and Pterophytes are both plant divisions with a common ancestor, they have little in common. While Bryophytes (mosses) are generally nonvascular and very short in height, Pterophytes (ferns) are vascular plants that usually grow much taller than mosses. While the dominant generation in mosses is the gametophyte, ferns exhibit the sporophyte generation. The details of their alternations of generation vary as well, although both have diploid and haploid stages. Alteration of ge...

At the end of the chromosomes there are regions of DNA that do not code for any of our characteristics but which appear to protect the chromosome. (Amador, 2000). As cells age, these regions of DNA, known as telomeres, become shorter. It is not known whether this is a cause or an effect of ageing. However, in cancer cells the length of the telomeres remains constant and they have high levels of an enzyme called telomerase, which rep...

Law Of Segregation Recessive Allele Alleles
336 wordsGregor Mendel played a huge role in the underlying principles of genetic inheritance. He grew up in a Augustinian brotherhood where he learned agricultural training with basic education. He then went on to the Olmutz Philosophical Institute and then entered the Augustinian Monetary in 1843. After 3 years of theological studies, Mendel went to the University of Vienna where he was influenced by 2 professors, the physicist Doppler and a botanist named Unger. Here he learned to study science throug...

Identical Twins Sexual Attraction
770 wordsDoes A Gay Gene exist? Two possible ways the genetic material for homosexuality may be transmitted J. Michael Bailey of Northwestern U. and Richard C. Pillard of Boston U. did a study on 161 gay men. Each had at least one identical twin or fraternal twin or adopted brother. Fifty two percent of the identical twins were also homosexual, as compared with twenty two percent of the fraternal twins and eleven percent of the adopted brothers. Similar studies have been done by Dean Hammer and others wi...

This is a type of microscope that makes use of a beam of electrons rather than visible light. Because the wavelength of electrons is much smaller than the wavelength of visible light, an electron microscope not only gives a high magnification but it also has high resolution. This means that details can be seen clearly. An electron mic...

Chances Of A Miscarriage Situ Hybridisation Test
233 wordsFlourescence in-situ hybridisation is a great advancement in technology because there are fewer chances of a miscarriage, the parents receive faster results, and the tests are easier to do. In the future, FISH will be able to decrease the chances of a miscarriage by using samples of maternal blood instead of amniotic fluid. The problem with amniocentesis is it uses a hollow needle to take fluid from the mothers uterus. The needle could damage the developing fetus if not inserted properly. Anothe...

Male Or Female Male And Female
1,553 wordsIs It a Boy or a Girl? On the surface, people tend to look at gender as a very definable yes or no matter and fail to see the variations that exist. Underneath the surface there exists a minority group who experience gender dysphoria: unhappiness or discomfort experienced by one whose sexual organs do not match ones gender identity. So, unless there exists an absolute distinction between identifying male from female, then classifying a transgender female as male is a product of gender identifica...
