Introduction: Cancer is defined by abnormal cell division without control. Colorectal cancer may be develop in the tissues of the colon and/or the tissues of the rectum (PubMed Health, 2015). Colon and rectal cancers arise because of changes that occur in specific genes and it has been notices that these genes play an important role to the cell cycle, angiogenesis and other mechanisms that take part in the growth of cells (Swan, 2005). Colorectal cancer is the third most common cancer worldwide…

How do scientists explain and support the argument for biological evolution? From the recent trip to the Minnesota Zoo, labs performed in class and multiple readings these things have shown students the dynamics of evolution. Scientists, like Charles Darwin, who have focused studies on certain organisms like the Galapagos Island finches have played a large role in our knowledge today about biological evolution, natural selection and descent with modification. Over many generations and an…

with ileal disease. Subsequent studies suggest that CARD15 genotype is associated not only with the onset of disease but also with its natural history. A study in a German and Norwegian cohort showed that patients with 1 of the 3 identified risk alleles for CARD15 were more likely to have either ileal or right-colon…

childhood maltreatment increases appetitive anticipatory response to drug relapse and diminishes engagement of regulatory and controlled action selection processes in response to stress and anxiety; heightening the cravings for the use of drugs. The allele of the human dopamine, DR4.7 just like the deficiency in neprislyin, also increases the dependency on alcohol and drugs over time. While, traumatic stress disorders such as childhood maltreatment and traumatic brain injury; can cause the…

Evolution is a change in allele frequency in a population over time. This is the passing of genes from one parent to children. This is not the same thought process that people lean toward. People tend to think of evolution as people evolving from monkeys over time. It is a change in a species over time. Evolution is a change in allele of species over time. An individual carries multiple traits from their parents allowing them to pass these genetics down to their children. This is the theory of…

A genotype is known as the complete genetic makeup of a given organism. Consequently, a genotype is the one responsible for the phenotype of an individual. In eukaryotes, a single genotype is capable of expressing more than one phenotype (observable characteristics). This possibility is because genes can go through lots of differentiation processes like mutation, changes in gene expression and frequency. So, mutations play a significant role in variation. For example, DNA can be affected by the…

He describes the ABO alleles and how the pairing of some may help protect someone in different geographical areas of the world from diseases. But each blood type is distributed around the globe and not distinctively between countries. For example, he displays a model that shows…

Thirty years ago, one-third of the childhood population was obese, today those number have tripled (Silverstone,Teatum). There is an immense divergence in being overweight and being obese. Overweight is simply weighing too much and obese means having too much fat (www.medlineplus.gov). “Overweight is the 85th to less than the 95th percentile and obese is the 95th percentile or greater (www.Cdc.gov).” Parents have became more lenient on their children’s intake of food and are not setting…

non-heritable traits is eye color, hair, your weight,etc. We can track the possible ways the genes will be distributed in offspring. There are mostly 2 copies of a gene at each gene location on the chromosome, one from each parent. Each copy is called an allele. Many homozygous genotypes parents were more closely related less genetically diverse. More heterozygous genotypes were distantly related more genetically diverse. We can use a punnett square to predict the probability of genotypes of…

Huntington’s disease is a progressive and fatal type of dementia caused by dominant allele in chromosome 4. (Kail & Cavanaugh, 2016, 2013, 2010, p. 44) It is an autosomal-assertive, progressive neurodegenerative affliction with a definite phenotype, including chorea, lack of coordination, cognitive deterioration, and behavioral difficulties. (Perandones, Micheli, & Radrizzani, 2010, p. vii) Huntington’s disease was identified by George Huntington in 1872. Huntington Disease is also referred to…
