RNA

A. SIGNIFICANCE: Lack of knowledge of the key molecular players and signaling pathways is a critical barrier to the progress of understanding the role of new protein synthesis in specific components of neural circuitry for establishing long-term memories. The proposed project addresses this important problem by employing a multidisciplinary approach in which we systematically combine tools of imaging, state of the art genomics and bioinformatics, molecular biology, functional analysis and…

An isotope is an atom containing different numbers of neutrons, differing in atomic mass. Basically an atom with a different atomic mass. What’s special about radioactive isotopes is that a radioactive isotope has a nucleus that decays spontaneously giving off particles and energy. 6. Radioactive tracers are used in science to label certain chemical substances, so metabolic processes can be followed and substances can be located in an organism. Radioactive tracers are important diagnostic…

and The Hepatitis C RNA Qualitative Test. The Hepatitis C Antibody Test is screening test on your blood to see if you have ever had Hepatitis C. The tests check to see if antibodies are detected in your blood. If the test shows negative, then you have never been exposed to Hepatitis C and more testing is not necessary. If the test is positive, then you have had Hepatitis C at one time or another but does not shoe if you have it now. This is when you would get the Hepatitis C RNA Qualitative Test…

of HIV from mother to child during birth. Zidovudine was approved by the Food Drug and Administration on 20 March 1987. It is an analogue of thymidine. Zidovudine inhibits the activity of reverse transcriptase, an enzyme of HIV, which converts HIV RNA into viral DNA. NRTIs interrupts reverse transcription, hence it prevents HIV from multiplying and prevents HIV infecting human cells. This drug is always used in combination with other HIV medicines. Zidovudine is available in the name of Retrovir…

This could also lead to evolution, survival of the fittest, overpopulation and the extinction of others. Limiting factors can be many things like space, food, light and many other things. For Sunflowers and example that would lead to carrying capacity would be if all the organisms that consumed or killed the plant would be removed from its environment by an invasive species or environmental changes, then the Sunflowers would grow faster and closer to each other. This would cause space, water,…

1.1 The structure of DNA Deoxyribonucleic acid (DNA) is often referred to as “the molecule of life”. It encodes the instructions that are used in the development and functioning of all known living organisms. The molecule itself was first discovered in 1860 by Friedrich Miescher (reviewed in Dahm 2005). Further work was performed by other chemists, including Phoebus Levene who identified the components of the molecule, including the presence of ribose sugars and phosphate groups, as well as four…

It is a member of the Picornaviridae family and is said to be a simple virus. It has a protein capsid that encircles the virus. The genome is a single stranded positive-sense RNA and relatively short being less than 8000 nucleotides long. It is a non-enveloped icosahedral protein coat. Poliovirus does nnot naturally affect any other species other than the human species. Mammals with the CD155 protein can be infected with the…

We know what life is. However, we do not know where life came from. Many extraordinary and intellectual people have come up with the most reasonable theories of how “life” came to be. From life being found on different planets, to life being found intriguing places of our very Earth. The Primordial Soup Hypothesis was a theory created by Alexander Oparin and Haldane in 1920. This theory stated that life started from a body of water and amino acids. The beginning of life began as…

treatment was 42% and in control 44%. Finally the mean age for treatment was 87±7 and for control was 86±9. Then, RNA was extracted, processed and recorded to create a database of AD (Karch et al. 2012). Finally, the study was replicated. Results showed that genes such as ABCA7 are associated with high levels of CDR (Clinical Dementia Rating) and genes related in function, might be related in RNA composition (Karch et al. 2012). Although this research did not violate any ethical guidelines to…

The nucleolus which is also known as the brain of a cell, is the most significant part in the nucleus. It takes up about 25 percent of the nucleus and it is not surrounded by a membrane. Through a microscope, the nucleolus is a big dot in the middle of it. It can be found in an animal, plant, diploid, and eukaryotic cell. It was found in the eighteenth century but its function wasn’t discovered until the 1960s. The nucleolus lives in the nuclear matrix. Sadly, the nucleolus is one of the…
