In this experiment, we are investigating the strength of the ratios discovered by Gregor Mendel in both the monohybrid and dihybrid cross. The ability to test these ratios stems from the use of Mendel’s law of segregation which states that during meiosis allele pairs will separate in gametes so one of each allele is present…

An Introduction Into the Dynamics of the Founder EffectPopulations are divided by geographic boundaries, confining a specific region/group of people to share and distribute its genetic traits within themselves without outward influence. The size of these populations is dependant upon whether certain mountains, rivers, deserts, oceans, or other extreme geographical, cultural, or technological conditions determine…

When going over the cell cycle, mitosis and meiosis are two major components. Mitosis is the division of the cell’s nucleus, and is followed by cytokinesis. Cytokinesis is the division of cytoplasm. Mitosis is only one phase that a cell goes through in the cell cycle. Also the mitotic phase is one of the shortest…

The article by Miyazaki et al. is a case report that involves an elderly male patient diagnosed with acute promyelocytic leukemia and unique chromosomal rearrangements. In addition to the hallmark translocation between chromosomes 15 and 17, the patient also carried additional related chromosomes. The report provides insight into the use of classical karyotyping, fluorescence in…

TELOMERE AND TELOMERASE Essay, Research Paper An Introduction To Telomere and Telomerase The telomere-telomerase hypothesis of aging and malignant neoplastic disease is based on the findings that most human tumours have telomerase activity while normal human bodily cells do non. An emerging hypothesis is that the up ordinance or reexpression of telomerase is a critical…

Science has built a reputation for breaking boundaries.  Science never treads lightly along the great unexplored frontiers, whether those frontiers be space, sea, or any other object of wonder and speculation.  Yet perhaps humanity’s most enduring curiosity resides in itself. Whether one considers the human mind or the human body, no subject has remained as open…. or as…

A continuing concern is that pigs have different lifespan than humans and their tissues age at a different rate. Disease transmission (excisions) and permanent alteration to the genetic code of minerals are a cause for concern. Genetic engineering, recombinant DNA technology, genetic modification/ manipulation (GM) and gene splicing are terms that are applied to the…

Although a rare occurrence, cases of babies switched at birth in a hospital have made the news in the past. Since an individual’s DNA sequence is unique, with the exception of identical twins, DNA fingerprinting is a reliable method used to determine the parents of a given baby. DNA fingerprints can be derived from restriction…

Cri-du-chat syndrome gets its name from the French language meaning “cry of the cat.” It is called this because one of the symptoms is a high-pitched signature scream or cry that comes from infants with this syndrome. The cry comes from abnormal larynx development. Every chromosome has a p arm and a q arm that…

The Cystic Fibrosis GeneCystic fibrosis is an inherited autosomal recessive disease that exerts its main effects on the digestive system and the lungs. This disease is the most common lethal genetic disorder in Caucasians, affecting one out of 2,500. On the bioethical front, CF was the first human genetic disease to be cloned by geneticists….
