RNA interference

In order to prevent a virus we must first learn its history; how it came about and where, we must then take into perspective how it is spread and then take preventative measures to ensure that the minimal amount of people are infected. A virus is simply defined as a non-living, infectious agent that must use a host cell in order to replicate. What makes these viruses so dangerous is that they’re numerous, and thus easy to spread and catch. This is not to say that every virus affects us, some…

components of coenzymes and proteins (Axtell). Controlling gene expression via miRNA is the plant’s way of responding to limiting levels of these essential macronutrients. miRNA works by binding to single stranded mRNA which creates double stranded RNA. Thus the plant identifies the new double stranded mRNA as inferior and attacks it. For the experiment, there were four microRNAs used including miR156, miR395, miR398, and miR399. miR156 was the control and has no nutrient requirement so it…

Neuroblastoma and microRNA- 34a is commonly mentioned together in many articles and studies around the world. With the advance in medicine and new discoveries, there has been found a dependence relation of neuroblastoma with these specific type of microRNA since it has been discovered how it could eliminate cancer eternally. MicroRNA-34a has not only revolutionized scientists but the world in general because of its ability to destroy neuroblastoma but also because is a new natural genetic…

Molecules and cells are the building blocks of development. The cells in our body performs different functions, which makes development possible. DNA contains instructions needed to tell cells what to do. RNA transfers the instructions to make proteins, which acts as receptors of signals in the brain. If RNA translates the wrong instruction from DNA, PKU could be the result, and children could become intellectually disabled. This all shows that biology is clearly a big role for human…

the nucleus of a cell origin and its significance is the beginning or the core that shape our lives. “Like the stone in a cherry, it is found in the center of the cell, and like this stone keeps its precious kernel in a shell” (p. 404). What Role of RNA and DNA in future life events?…

THE ROLE OF ELONGATION FACTORS IN GENE TRANSLATION AND PROTEIN SYNTHESIS. Professor Kinzy’s lab seeks to investigate the structure and function of G- protein in relation to it’s regulation and the post transcriptional processes associated with gene expression. The lab uses Translation Elongation apparatus found in yeast to investigate these processes. The components of these elongation factors are important targets for antibacterial and antifungal drugs such that improper expressions and…

Kary Mullis was born December 28, 1944. Mullis worked as a DNA chemist for 7 years, He also invented the polymerase chain reaction. Kary Mullis was born in Lenoir, North Carolina. Mullis is 71 years old, He’s also been married 3 times. He wrote a quote stating “Art is subject to arbitrary fashion”. Kary Mullis accomplishments were very overall. His invention of the polymerase chain reaction chain reaction helps specific segment of DNA results quickly and accurately. Methods obtaining a…

The title of the video, “Ghost in your Genes”, is very appropriately titled because it discussed the various appearances of phenotypic differences among organisms with identical genomes. In the mid to late 1900s, scientists were convinced that DNA sequences were solely responsible for every trait evident in organisms. After the human genome experiment, which involved compiling and analyzing genomes of thousands of different people, it was determined that humans have around 25,000 genes, far…

Caulobacter Crescentus is a dimorphic, α-proteobacterium found in oligotrophic environments. Their dimorphic cell cycle produces two morphologically and functionally different daughter cells, known as the stalked cell and the swarmer cell. The stalked cell remains anchored to the substratum and is sessile, while the swarmer cell is motile. Upon chemotaxis, the swarmer cell disperses in search of nutrients. Once sufficient nutrients are located the cell cycle can continue. In the early phases of…

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:…
