Ribosome

The lab focuses on three types of eEFs; eEF1, eEF2 and eEF3 with most focus on the eEF1 which is the prototype of G- proteins. The EF1Alpha (eEF1A), a component of EF1 is GTP- dependent and its function is to accurately attach aminoacyl-tRNA to the ribosome. The other component of eEF1 is the eEF1Balpha, a guanine nucleotide exchange factor (GEF) found in yeast. Its function is to catalyze the exchange of GDP for GTP to maintain the pool of active protein. The use eEF1B free genetic system…

RNA Polymerase. The final mRNA strand which is produced is complementary to the original DNA strand. The mRNA is free to leave the nucleus through the nuclear pore and attach itself to a ribosome where translation takes place (OCR, 2008). The second stage is the process known as translation where the ribosome ‘reads’ the mRNA in chunks of three (codons). Each codon codes for a particular Amino Acid (AA) which is then binds to the mRNA strand using a tRNA. When a second AA is brought, a peptide…

The role of tRNA is to carry amino acids to the ribosome. The act almost as a bridge matching a codon is an mRNA with the amino acid that it codes for. Every tRNA consists of a set of three nucleotides called anticodons. The anticodon of any given tRNA can bind to one or more mRNA codons. There are many different types of tRNAs inside of a cell. Each contains its anticodon and matching amino acid. The tRNAs bind to codons inside of the ribosome, where they will then deliver amino acids for…

In a cell there are many organelles to help keep the cell functioning. In the cell you could have a cell wall, cell membrane, ribosomes, cytoplasm, flagella, cilia, nucleus, nuclear membrane, nucleolus, chloroplast, Golgi apparatus, lysosomes, mitochondria, plastid, rough endoplasmic reticulum, smooth endoplasmic reticulum, vacuole, and a vesicle. Everyday items can represent many of the organelles. One example of this is by looking at a house. In a house you have a fence. The fence in your…

For decades, scientists have conducted research on all living things; to help us determine what life is, what life does, and why things live. During life, several miraculous things take place, and among those things is change. Change that can start a chain reaction over decades, centuries, even millenia. We call these changes evolution. There are, however, several doubts in the minds of people; most commonly, those people who believe in the words of the Bible. If evolution is a real thing, then…

Organelles work together to maintain a cell's internal process and functions by providing the necessary needs for the cell. Although this mainly applies to Eukaryotic cells, this can also apply to Prokaryotic cells. Prokaryotic cells perform some of these function, but in a simpler way. Organelles work together to protect the cell, provide energy, repair the cell, direct the cell, and clean up the cell. First, organelles work together to protect the cell. The cell membrane is the main organelle…

Prions, endospores, and mycobacterium all are extremely resistant to antimicrobial treatment. Prions are extremely small, even smaller than viruses. Heat or formaldehyde aren’t very effective against prions. Endospores are extremely resistant to harsh conditions as well. They can survive heat up to 100 degrees C, drying, radiation, and majority of chemicals. Mycobacterium are extremely resistant due to their waxy cell wall. This cell wall blocks many things from entering the bacteria, making it…

“I'm super nervous to meet the coach today” she says. She drives to practice. She meets the coach Bob. She thinks in the head the coach is kinda like the chromosomes because they teach you information about softball and how to hit a softball and catch a ball. The chromosomes In the cell Helps direct cell activity and stores necessary information for building proteins. “We are going to run a baseline drill” the coach says. (The girl) says to her friends “ isn't the baseline a little bit like the…

Chloroplast (Plant cells only) - Small oval structure containing chlorophyll giving the chloroplast a green pigment. Chloroplast uses the sun’s energy to create food for the plant, this is known as photosynthesis. Cell wall (Plant cells only) - Provides structure and protection to the cell in the form of an outer layer. This organelle lets H2O, CO2, and O2 pass through it. One large vacuole (Plant cells only) - Large sac filled with fluids. The vacuole in a plant cell stores, large amounts…

cell (i.e. ions, viruses, etc). Also the cell membrane is what helps hold the cell and all of its organelles Endoplasmic Reticulum (AKA the ER), smooth and rough whats the difference? The smooth ER does not have any ribosomes while the rough ER is covered in the protein producing ribosomes. Because of this the smooth ER does not produce proteins while the rough ER does produce the previously mentioned proteins. In addition the ERs are crucial in the exportation of proteins in the cell. The ER…
