    • 11 Pages

    The Ebola virus is gaining worldwide fame due to its sensational outbreak originating from Sierra Leone. The outbreaks of the virus have been recognized and effectively dealt with in the past, but the present outbreak is becoming a overwhelming challenge. Approximately there have been 15,000 suspected cases of the disease and 6,000 confirmed deaths so far. The horrifying visual hemorrhagic symptoms caused by the Ebola virus include internal and external bleeding as well as the fear inducing…

    Human Epigenetics

    • 1179 Words
    • 5 Pages

    Epigenetics, a contemporary and often misunderstood topic in the field of biology, was first defined in the early 1940s as “the branch of biology which studies the causal interactions between genes and their products with bring the phenotype into being” (Dupont 2009). Since then, as understanding of the human genome has developed and grown, a complex array of errors and dysfunctions in the processes of gene regulation, expression, and replication have been shown to cause, or correlate strongly…

    differences, each silencing method has specific advantages and disadvantages. Two of the most currently understood methods of gene silencing are RNA interference (RNAi) and antisense oligonucleotides (ASOs). In RNAi, the molecules that identify the target mRNA are called small-interfering RNAs (siRNAs). These siRNAs are short, synthetically made double-stranded RNA molecules (Koenig et al. 2013). The combining of…

    replication of itself mRNA transcribes DNA, tRNA translates mRNA into proteins. A pattern on nucleotide on a DNA strand is called a gene. The Central Dogma of molecular biology is: DNA codes for RNA which codes. for proteins Not all genes are expressed for the production of proteins, some have other tasks like making RNA. Some proteins are structural. Some proteins are made of hundreds or thousands of amino…

    interact and generate a phenotype that was not expected in light of each of the gene’s effect [1]. In mammalian cells, most of the genetic interaction assays use RNA interference (RNAi) techniques [3], which is method of silencing a gene based in the degradation of specific messenger RNA (mRNA) molecules. Described initially in plants, RNA interference was also observed in most of the eukaryotic organisms, such as insects, mice, and humans.…

    used to build a protein in a two-step process. Transcription is considered to be the first step of gene expression. It is known to be the process of making a copy of genetic information stored in a DNA strand into a complementary strand of messenger RNA (mRNA). The process of eukaryotic transcription can be separated into three phases, initiation, elongation and termination. This complex process involves various cell signaling methods as well as the activity of many enzymes. Genes are segments…

    Gene Drive Effect

    • 1308 Words
    • 6 Pages

    Introduction Gene drives are a controversial new invention made to affect genes of a species, which can potentially eliminate animal spread diseases. A gene drive refers to a genetic system that manipulates a gene, guaranteeing all offspring to contain a certain dominant trait. As the trait is dominant it eventually spreads throughout the whole species, allowing them to all contain the manipulated trait. Scientists have designed this in order to eliminate mosquito-transmitted diseases such as…

    proteins are the workhorse of the cell, as they make up most tissues and organs of the body. Lipids are the storage areas. They contain the extra energy that the organism does not currently need. Nucleic acids are the parts of cells that include DNA and RNA, which dictate cell replication, and specialization. Every single organic molecule, from carbohydrates to nucleic acids is just as important as the other. All of the molecules play significant roles in allowing the organism to function…
