At one point in the universe’s long and ongoing history, evolution began with the smallest of sea creatures. Since then, there have been many waves of evolution, and with genetic engineering, humankind will be able to remain adjustable to lifestyle and environmental changes. It may potentially be the peak of the “fittest” that Darwin proposed in 1869. Genetic engineering is not a science fiction fantasy anymore either- is it legitimate and it is growing. Will you grow and adapt with genetic…

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 fusion of chromosomes, aneuploidy, and deletions, duplications, inversions, insertions,…

inherited factors, known as genes1. Genes are units of heredity on a chromosome that bring about our existence and create diversity. This diversity arises from the fact that there are different forms of genes known as alleles. All the alleles of an organism are referred to as that organism’s genotype and results in an organism’s phenotype, or physical appearance (ie. Widow’s peaks are a human phenotype that results from the genotype ww)2. To study inheritance of genes, Mendel used a punnett…

abnormalities would be placed into the mother’s womb. This technique is targeted for parents who have a high risk of passing a fatal inherited disease to their offspring. It can benefit society by preventing a child whose parent is carrying copies of the genes for a disease such as Huntington’s from becoming affected (Sermone). Huntington’s disease (HD) is a progressive disease in which…

Selective breeding is the human interference in the genetic transfer in animals and plants. Humans take the idea of natural selection where instead of the environment selecting for the alleles that are best suited for the organism to survive in the wild, humans select rare desirable phenotypic traits in organisms and breed them with each other in order produce an offspring containing those traits. Desirable traits include leaner meat in animals, or better quality milk in cows for commercial uses…

cause diseases leads to a low life expectancy, increased health issues in the population which could be increased if the amount of faulty alleles were to increase in the population naturally and the number of beneficial alleles were to decrease in the gene pool without any interference by humans and it will not beneficial to the population, therefore is why human manipulation…

through Gene Therapy and Selective Breeding Gene Therapy → explain the processes involved Gene therapy is the process of altering an existing gene in the DNA and inserting it into cells in an organism to fix genetic disorders or diseases. In humans, gene therapy is the process in which some of the defect cells or the cells carrying the disease are removed from the body (eg. lung cells in a Cystic Fibrosis patient) in order to harvest their DNA. The base sequence of their DNA is then altered to…

affected patients have inherited or spontaneous deletions in the dystrophin gene that disrupts translation and results in incomplete proteins. Sufferers of DMD have difficulty climbing stairs, muscle weakness in arms and neck, and progressive muscle-wasting1. It appears that error in gene expression and heredity are the two main causes of DMD. DMD, to this point, has no cure and after identifying the location of the DMD gene mutation, the goal is to restore transcription or to at least restore…

paragraphs we will discuss what genome evolution is, how genomes are able to be compared and how the size can contribute in to that, the gene functions and expressions, applying comparative genomes and the evolution within genomes. So what is a genome? A genome is the complete DNA sequence of an organism. The Genome is a compilation of the stored DNA in genes on the…

What are sudoriferous glands, and where are they located? They are sweat glands and they are located throughout the body. 11. What is sweat composed of and what are two functions of sweat? Water, salts, urea, uric acid, amino acids, ammonia, sugar, lactic acid, ascorbic acid, and pheromones. Two functions are to regulate body temperature and rid body of waste. 12. Name two types of sweat glands and differentiate between the two. Eccrine and Apocrine sweat glands. The apocrine…
