Ribosomal RNA

Kanamycin acts by binding to the active site of the small s-ribosomal subunit, an important functioning part of the organelle. Kanamycin inhibits the synthesis of the protein by causing an increased amount of mistranslation. The other antibiotics used in the experiment are Tetracycle and Streptomycin, both which act…

Erwin Schrödinger was a physicist pioneer who gave a series of lectures in 1944. They were published under the title What is Life? (Harold, 2001). Though philosophical in nature, many have wondered if life can be reduced to biology or even further down to chemistry. This sent many scientists looking for the answer and spawned the guiding question, could human life be artificially created at the cellular level? This would consist of arranging the correct amounts of various elements into the…

In the 1940s, antibiotics were widely introduced as a cure for common types of diseases. However, some microbes were able to resist the impacts of these drugs, in other words, the pathogen remained alive. In order to help resolve the crisis, antibiotics were found through screenings of soil microorganisms. However, soil microorganism’s antibiotics were depleted by the 1960s and their antibiotic effects were unable to be replicated through synthesis. In this experiment, the researchers developed…

1. Why is the cell theory significant (don’t just state the tenets, explain what it means and why it is a theory)? The cell theory is significant because of it’s three basic ideals or principles. The first is that all organisms are made from cells. This means that cells are the building blocks of life and technically, all of life is connected and related to each other by this tenet. In addition, by researching and examine one type of cell, the results can be assumed for all similar types of…

Despite humans encountering if for millennia, pneumonia caused by Streptococcus pneumoniae remains one of the deadliest microbiological threats facing humanity today. S. pneumoniae is a Gram positive, diplococcus bacteria with ore than 90 serotypes1. Along with pneumococcus pneumonia, S. pneumonia can cause meningitis, sepsis, bacteremia, and otitis media1,2. It is the leading cause of community acquired pneumonia, as well as fatal respiratory infections globally, across all age ranges; severe…

all of these are necessary for the mitochondria to function. These functions include providing instructions for enzymes to create the cell’s main energy source ATP. Also the remaining genes take part in the transfer of tRNA and rRNA. These types of RNA help construct amino acids into functional proteins. These proteins that are generated are involved in the cellular respiration process, which is the process of converting chemical energy from food to ATP. ATP is the main source of energy that…

28. a) A structure that was made if two chains of nucleotides, each in a helix, with each chain running parallel to each other. Also proved that the nucleotide bases could pair up in only one way based on Chargaff’s rule. b) Franklin’s x-ray diffraction photographs showed that the wet form of DNA likely had a double helix. Wilkins showed Watson Franklin’s results and at the time Watson and Crick were experimenting with many potential models of having 1,2 or even 2 strands. As soon as Watson saw…

Results Primer design and LAMP reaction Among 40 different primers (OPA 1-20 & OPB 1-20 series) screened by RAPD PCR for differentiating the Mycosphaerella eumusae from other leaf spot causing fungal pathogens in banana, only the primer OPB 10 has generated a unique amplicon specific to M. eumusae at 1300 bp size. A total of nine different sets of LAMP primers were designed based on this specific SCAR derived RAPD marker sequence of M. eumusae and screened for the production of LAMP products…

Cell Biology Beta cells in pancreatic tissues are described as eukaryotic cells and not prokaryotic, this is because the cell is larger in size and there is a true nucleus present which contains DNA. In prokaryotic cell there isn’t a nucleus and the DNA is free within the cytoplasm. Also Beta cells have many organelles and there is mitochondria present, which in a prokaryotic cell there are fewer organelles and there aren’t any mitochondria present. Beta cells in the pancreatic tissue release…

My first interaction with a patient was when I volunteered at Med Globe clinic, a general practice in Atlanta known for its population of lower socioeconomic patients. I walked in and saw old equipment, no electronic records, one doctor, and a few nurses—but a large number of people in need of care. The first patient I met was a 6-year-old girl who was a Spanish-speaking native. Smiling down at her curious face, I tried to see myself through her eyes. Did I seem friendly? Did she trust me? Her…
