    The photographs taken from the Franklin home were released by the Los Angeles Police Department last week. The women’s faces in the photos looked like they were unconscious, asleep, or dead. These women were mothers, daughters, and sisters who had families that will never get their loved ones back. It was a abhorrent case that is part of history today. Women left behind children, spouses, and families. I cannot imagine what the women who were captured by this Lonnie Franklin. At this time the…

    genome sequenced. Some companies have already started performing sequencing for profit. While clinical studies, perform and disclose results genetic sequencing to participants. However, there are scientific, and ethical issues surrounding personal DNA sequencing. Despite this, the advantages outweigh the disadvantages. I would get my gene sequencing because it can illuminate important information. Specifically, I want to know about medically actionable genes, genetic diseases I can develop,…

    The CRISPR system works by cleaving a point along foreign DNA and placing what are called “spacers” in order to stop or reduce the effect that pathogenic DNA has by developing an immunity in that pathogen because it has been introduced in small portions into the host’s sequence. The CRISPR/Cas system is capable of cleaving almost any DNA sequence as long as the design of the crRNA has the appropriate binding region for the system. It is uncertain…

    saying that we shouldn 't be doing this? Or is it only one simple downfall to the many pros? Unfortunately, there isn 't much research to back nor defeat GMO 's, which raises another question. Do we really know what were handling? The genetic code and DNA sequencing of an organism is very gentle and delicate, one base off and situations such as Cystic Fibrosis occurs. Yet, we 're able to handle it carefully and with enough care to create apples that will never bruise, or tomatoes that will never…

    method uses molecular techniques to identify bacteria by doing DNA or RNA analysis of the bacterium’s genome ("Conventional Bacterial Identification Methods", 2013). The 16S rRNA gene sequences provides species-specific signature sequences useful for bacterial identification ("16S Ribosomal RNA Sequencing Theory”, 2016). The 16s rRNA gene sequence uses a polymerase chain reaction (PCR) to amplify a specific DNA target from a mixture of DNA molecules, which helps in the identification of…

    through the efferent arteries and to the rest of the body. Because a shark’s blood pressure is very low, they must be constantly moving to keep circulation going. Chromosomes are structures of protein and nucleic acids found in the nucleus that hold DNA in the form of genes, which are transferred from parent to offspring which determines the order of the monomers in a nucleic acid molecule. A haploid cell means that it only has half the chromosomes, so it’s from one parent, while a diploid…

    genotypic differences that can be observed using DNA sequencing data. One way to observe genetic variation amongst humans would be to sequence the Mitochondrial DNA(mtDNA). Mitochondrial DNA is the most commonly used DNA to form phylogenetic trees. Human Mitochondrial DNA is about 16,500 bps in size and consists of 13 protein coding genes, 22 tRNAs (transfer RNA), and 2 rRNAs (ribosomal RNA) (Ingman, 2001). Mitochondrial DNA has many beneficial uses for DNA sequencing such as; its ability to be…

    Introduction Evolution Canyon is a canyon in Israel where the two slopes face very different conditions. The Northern Facing Slope (NFS) is lush, green, and shaded while the Southern Facing Slope (SFS) is dry and has little protection from intense sunlight. Evolution Canyon is a natural laboratory, meaning that nature has provided variations, allowing it to be a great location for experiments. Specifically, it is a great location to study natural selection and evolution. Researches from the…

    then help fight off the disease (Genetics Home Reference, 2016). Gene therapy was first discovered around the 1960s and 1970s, however it was only the concept of the experiment. In 1970, Stanfield Roger proposed an idea that defective DNA could be replaced with “good DNA”. This was later cited by Theodore Friedmann and Richard Roblin in their paper called “Gene therapy for human genetic diseases” created in 1972 (Robertson, 2010). In 1990, the gene therapy process was finally used to help treat…
