Ribosome

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…

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…

the 5’ end, and a string of A’s called the poly-A tail would be added to the 3’ end. Next, RNA splicing, the removing introns, generally non-coding of areas of the gene, would be catalyzed by the spliceosome, a large complex of proteins and small ribosomes that cuts introns out of mRNA. This process could also be catalyzed by a ribozyme, an RNA molecule that also functioned as enzymes. Many ribozymes are interns that cut themselves out of a pre-mRNA sequence. This would result in a shorter…

is determined by 3-letter codes in the messenger RNA. “Synthesis of RNA deriving from a DNA template is known as the transcription process. Only one strand of DNA is imitative. After transcription, the DNA strands rejoin.” (Gene expression n.d) Ribosomes that synthesize proteins consuming the mature messenger RNA transcript produced during the transcription process, happens during the Translation process. Recombinant DNA is produced by merging DNA from two or more outlets. The process frequently…

All cells are derived from pre-existing cells - through the process of meiosis and mitosis 4. In a multicellular organism, the activity of the entire organism depends on the total activity of its independent cells 3 Significance of technological advances to developments in the cell theory Assess the impact of technology including the development of the microscope on the development of the cell theory The development of cell theory has been heavily impacted by the improvement of technology. The…

As we all know and have been studying as scientist that the cell is the basic unit of life. The cell provides structure for the body, takes in nutrients from food, convert those nutrients to energy and carries out specialized functions. The cell is composed of many parts, all with different functions. The cell is made up of two major parts which include the nucleus and the cytoplasm. The nucleus is surrounded by a nuclear envelope, which can also be referred to as the nuclear membrane which is…

GFP from a jellyfish the Aequorea victoria. The GFP, in the form of a plasmid called pGLO, was added to a sample of E. coli and a control was created of E. coli without it. The E. coli was then placed in either ampicillin or not as well as with a ribosome known as arabinose. The E. coli without pGLO died in the ampicillin and the ones with pGLO survived after a period of incubation, with the one that had arabinose glowing under ultraviolet light. This was the expected result due to GFP adding a…

oxygen to release energy, which needed for reactions in the cell. Endoplasmic reticulum: a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis Ribosomes: small structures in the cytoplasm of a cell where mRNA is translated into an amino acid chain. Golgi apparatus: a complex of vesicles and folded…

A protein is a macromolecule found in cells. A macromolecule is made up smaller molecules. Similarly, a protein is made of up of many smaller molecules called amino acids. Inside of a living cell. Proteins are built in the ribosome, an organelle inside of a cell. Many structures such as tissues and organs are made of proteins. They are the main components of hair, skin, muscle, heat and other important organs. Many important part of a living organism depend on these to proteins to function…

When there are genetic mutations that affect the cystic fibrosis trans-membrane conductance regulator (CFTR) protein, Cystic Fibrosis (CF) is the outcome. CF was recently linked to CFTR defects, which is a major gene, found on the seventh chromosome. Cystic Fibrosis is not only the most common disease among those of Caucasian decent, but it also happens to be the most deadly inherited disease that affects more often Caucasian Americans. In the United States one in twenty among Caucasians are…
