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…

1.1 Explain the appropriateness of light and electron microscopes for different purposes. Explain the difference between magnification and resolution (2) Magnification is how much you can enlarge an image Resolution is how sharp and clear your microscope can show an image State the resolution that can be achieved by each of the following types of microscope (2) Light microscope. 200nm Transmission electron microscope. 0.5nm Explain the appropriateness of light and electron…

complex that has an amino acid at one end and an anticodon recognized by the codon in mRNA at the other end. Translation occurs in three steps and takes place on a ribosome. The ribosomes are found in the cytoplasm, they have a large and small subunit, and a E, P and A site. During the initiation stage, mRNA and tRNA come together on a ribosome. The elongation stage starts when the start codon is translated, usually AUG. tRNA comes in it will be kicked to the A site, then another one will come…

What are the processes involved in cellular respiration? How do enzymes perform an important role in the mitochondria? How does the mitochondria use chemiosmotic gradients? How did the mitochondria evolve? The mitochondria are organelles found within eukaryotic cells, that produce energy for the cell. There are many chemical processes and important molecules involved in the mitochondria. Cellular respiration is the chemical process that makes the energy needed for the cell in the form of ATP.…

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…

some characteristics. No matter at which cell you are looking at: bacteria’s`, plants`, animals`, protists`, etc., they all will be bounded by a plasma membrane (Biology Department,2015), and contain a nucleic acid: such as DNA, RNA, cytoplasm, and ribosomes. The things that prokaryotes will not have are organelles. Organelles can be known as the parts of the cell, such as: Nucleus, ER, Golgi apparatus, etc. There are there domains that exist: Bacteria, Archaea and Eukarya(Biology…

cell. The nucleus instructs every single part of the cell what to do, and what the different organelles need to do. The nucleus includes chromatin (protein and DNA). It also contains Nucleolus (nucleoli is plural). These nucleoli are responsible for ribosome production. If the nucleus were to suddenly malfunction, this would mean that the cell would have no directions, and nothing to direct them, so all activity would completely stop. Cell Membrane: The cell membrane is the organelle in the…

in the 1960s ("Endosymbiosis and The Origin of Eukaryotes", 2016) revealing that other cellular organelles such chloroplasts, as being similar to mitochondria.This includes their self-replicating ability and a double mellbrane accompanying their ribosomes and DNA. Such evidence suggests, Chloroplast organelles were also once f8-living bacteria ("Endosymbiosis and The Origin of Eukaryotes", 2016). Given that the first eukaryotic cell evolved monGan a billion years ago (Cooper, 2000) these…

protein synthesis, there are two major steps; transcription that creates mRNA and translation that translation mRNA to translate into protein. Transcription happens in the nucleus, after the process of transcription, mRNA molecule is then sent to the ribosome where the message is translated into specific proteins. This process is called gene expression. Millions of cells in the human body contain about 23,000 genes that make up the human genome. Genes contain the information passed from parent…

Karamjit Singh Antibiotics report-back task 1. The 5 ways by which an antibiotic may disrupt or destroy a bacterial cell are : • The bacterial cell wall • The bacterial plasma membrane • Synthesis of bacterial proteins • Bacterial nucleic acids • Bacterial metabolism 2)Bacteria cell wall synthesis: While the cells of people and creatures don 't have cell walls, this structure is basic for the life and survival of bacterial species. A drug that…
