Creationism is the belief that both the Universe and earth were created through acts of divine creation. Creationism is believed by many religions, especially Christianity. Creationism has become famous due to the large debate concerning the science and religious aspects of the theory. The main portion of the debate is should the theory be taught in public high school biology classrooms. The theory of creationism should be taught in schools because, there is not a way to prove living creatures…

Is personality determined by heredity; where certain alleles are passed down into offspring and expressed in a variety of ways? Maybe it has something to do with upbringing and social interactions? Both? Personality is influenced by a variety of factors, with no singular clear cut explanation to fit every instance. This paper will explore the ways personality works the way it does, illustrating points with genetics, psychology, mental illness, the Myer-Briggs indicator and many more interesting…

Since I was a young girl, I have loved learning and discovering new things. Vacations from school, for me, have always consisted of visiting historical and educational places. I love visiting museums of any kind with the idea of learning new things. My passion for science and animals has only continued to grow and grow as I get older. In 7th grade, when I truly began taking science classes, I really became enthralled with all that there was to discover about things I knew and others I had never…

Dyskeratosis congenita (DKC) is a rare congenital disorder that results from defects in telomere maintenance due to mutations in genes coding for proteins that participate in telomere maintenance. It is a progressive disease with a highly variable phenotype, making diagnosis difficult. The disease is characterized by the classic triad of abnormal skin pigmentation, nail dystrophy, and oral leukoplakia (white patches in the mouth) (Figure 1) but these symptoms might not always manifest in…

Abstract Background: Understanding the variation in progression from normal to precocious puberty is a matter of concern. Beside idiopathic central precocious puberty, CAH is an important cause of gonadotropin independent precocious puberty that requires a comprehensive treatment regimen to achieve normal growth and pubertal development. Aim of the work: This study aimed to evaluate growth and pubertal changes in children with CAH. Also, to consider the idiopathic central precocious puberty.…

eukaryotes. Prokaryotes contain a single loop of chromosomal DNA which is stored in nucleoid. Eukaryotes DNA is found on tightly bound and organised chromosomes. Genetic expression is the process where genotypes coded in the genes are displayed by the phenotypes of the individuals. The DNA is then copied by the RNA and synthesized into protein. The process of transcription, which is the synthesis of RNA from a DNA template, is where the instruction of the gene expression is most likely to occur.…

1. Darwin’s theory of natural selection directly applies to the domestication of plants and animals in numerous ways. The first being that natural selection, or the differential survival and reproduction of individuals due to differences in phenotype is based on the idea that organisms pass genetic mutations onto their offspring that can potentially increase the success of reproduction and survival for future generations. Over time these continual genetic mutations can result in a new species…

Prenatal stress is important to study, due to research findings that suggest stress levels are associated with negative consequences in fetal and infant development. (1) The relationship between exposure to prenatal stress with increased reactivity to stress and cognitive problems in adulthood, indicating that the stress can effect on person at different periods of life.(3,4p+ nature) Stress has high prevalence during pregnancy .(2) When a person is exposed to stressful events , the brain…

SIMULATION CROSS BETWEEN A HETEROZYGOUS FEMALE AND A HEMOPHILIA MALE BACKGROUND INFORMATION The survival of the human species throughout the last millions of years has been solely based on the randomized process of genetic inheritance from one generation to the next generation. Instead of duplicating their genetic information and create identical offspring, humans produce sex cells, through the process of meiosis, that carry only half of the genetic information, and fertilize them in order to…

In healthcare today we are faced with many moral and ethical dilemmas, many of which have been created by the advent of newer technology. Some of the current topics include the 13-year-old girl in California declared brain dead, the pregnant woman in Texas who was declared brain dead and the hospital obeying the law to keep her on life support to get the baby to an age to deliver, the issues or reproductive technology---how many embryo to implant, genetic disposition (getting a baby with blue…
