RNA

neuronal wiring is similar to that of humans. We focused on the role of three sensory neurons in the nose of the nematode—the 1) AWA and 2) AWC neurons are involved in chemo-attraction and the 3) AWB neurons are involved in repulsion. With the use of RNA interference (RNAi), we diminished or eliminateed specialized proteins within the worms to test if their olfactory…

segments of DNA that contain short, repeating sequences. The repetitions are then followed by segments of DNA from the host DNA strand. A simple version, CRISPR-Cas9, has been modified to edit genomes. By delivering the Cas9 with a synthetic guide RNA (gRNA) into a cell, the cell's genome can be cut at a desired location, allowing existing genes to be removed and/or new ones added. CRISPR-cas9 is like a tiny pair of scissors that scientists can control. Once the strand of DNA is split the cell…

Lymphocytic Choriomeningitis virus (LCMV) belongs to the Old World arenavirus family of enveloped viruses (Buchmeier et al., 2007). LCMV in particular has served as model organism from many significant studies in the field of immunology such as the Nobel Prize winning study of the Major Histocompatibility Complex (MHC) by Zinkernagel and Doherty (1975). LCMV’s natural reservoirs are the common household rodents (Traub, 1936). Household mice have shown to attain persistent asymptomatic LCMV…

This is accomplished by adding salt and ethanol to a solution containing DNA or RNA. In the presence of salt (in particular, monovalent cations such as sodium ions (Na+)), ethanol efficiently precipitates nucleic acids. The purified precipitate can be collected by centrifugation, and then suspended in a volume of choice. PROTOCOL:…

September -The 30-ton rock, named after the town, was discovered on September 10 and dug up by excavation team which was shocked by its massive size.The original asteroid was estimated to have weighed about 600 tons and entered Earth's atmosphere at 14,000 kilometres per hour, where it broke up into a shower of smaller meteorites, according to Scientific American. August -Stanford lled a research shows that they were emerging in the memory technology, based on a new class of semiconductor…

CDV is an enveloped, non-segmented, single-stranded RNA virus and is a member of the Morbilliviruses, thus closely related to measles virus (LAMBandKOLAKOFSKY 2001; VANDEVELDE and ZURBRIGGEN 2005). CDV possesses a nucleocapsid containing the viral genome, which consists of the nucleoprotein (N) and the polymerase complex including the (P) and (L) proteins (DEMETER et al., 2007). The membrane protein (M) is located at the inner surface of the envelope, which exhibits two surface glycoproteins:…

3-2-1 Assignment- Genetic Inheritance 3 Main Points: 1. The cell contains three important things. Those three things are the nucleus, mitochondria, and the ribosomes. The nucleus consists of DNA and RNA molecules which contain hereditary information that has a jurisdiction of the cell’s purpose. The mitochondria contains mtDNA distinctive influence in human developmental research. Lastly, the ribosomes are the basic necessity to the process of protein synthesis. 2. Meiosis is a process where…

A human being and a chimpanzee are quite similar not because of physical features but because of the DNA, they inherit and what makes these species so unique to one another. All living cells contain DNA, which is the basic unit for growing, reproducing, and surviving. DNA, Deoxyribose Nucleic Acid is comprised of 4 different types of bases; adenine, thymine, guanine, and cytosine that are proteins. These 4 bases rely on each other because of adenine pairs up with thymine, while cytosine…

Genetic disorders may affect millions of people every few seconds around the world, and it’s our job to understand how they work or occur in order to try and prevent them or cause them from getting worse. With how far research has come over the years, we now know how genetic disorders occur. They occur from something called mutations, which I am sure mostly everyone has heard about. Most people just don’t understand exactly how mutations work, occur, or how they cause millions of different…
