    oxygen. They can grow in areas that would kill most organisms. It has distinct domains that make them extremophiles, meaning that they can grow in more than one condition. Additionally, prokaryotes include cells that have a nucleus, which makes them eukaryotes. It includes animals, plants, protists, and fungi. Archaea also have cell walls that do not contain the peptidoglycan found in bacterial cells. It also lacks the cellulose that is found in plant cells, it also lacks the chitin that is…

    The CRISPR-Cas9 system is derived from a bacterial adaptive immune system. The acronym stands for clustered, regularly interspaced, short palindromic repeats, which are sequences of DNA that read the same forward as backwards. In between these are sequences of DNA known as protospacers indicative of particular bacteriophages encountered by bacteria. These sequences are then used as a template for RNAs capable of recognizing viral DNA within a cell and as a means to bind the endonuclease CRISPR…

    Domain (IV), the clamp domain, primarily consists of hydrophobic and charged residues. Once MutS has detected a mismatch, ATP hydrolysis stops and a severe distortions in the conformation of DNA at the mismatch site occurs. The clamp has numerous hydrophobic and charged residues, which is consistent with a role in dimerizing with the charged residues of the clamp of MSH6. In addition, it may work to stabilize the highly unfavorable state of DNA when a mismatch is recognized. The positively…

    As a population, organisms look different. Genetic variations and phenotypic differences are a direct result of the processes of transcription and translation at the molecular level. In the paragraphs that follow I will discuss how the processes at the molecular level influence traits that we see at the species level. A human has 23 chromosomes, each of these chromosomes are a housing unit for DNA. DNA, also known as deoxyribonucleic acid, is a simple molecule found in all living organisms. DNA…

    All bacteria are lacking of a membrane-bound nucleus and other membrane bound organelles, classifying them as prokaryotes. In the six-kingdom system used by the United States, all bacteria fall into the taxonomic kingdom of either archaebacteria or eubacteria. Bacteria are all unicellular and microscopic regardless of which kingdom they are grouped in. In general, archaebacteria are thought to resemble the first living bacteria on earth and are normally grouped by the climate in which they…

    Livestock production and climate change affect and get influenced by each other. The most important effects of climate change on the environment and livestock include rise in temperature, elevation in sea level, alteration in microbial eco-system and several others effects, known or unknown which might affect the livestock positively or negatively. There have been various predictions about the quantum of sea level rise with varying degree of confidence because many of the natural phenomena have…

    Bacteria are coming from the Greek word bakteria, meaning little stick, even though the first observed bacteria was in a rod shape, bacteria can come in many forms, spirals, spherical in shape. In 1928 a British scientist named Frederick Griffith discovered that previously harmless bacteria could change their own nature and become capable of causing disease (Black, 2012) What exactly then is a bacteria? Is a microscopic living one cell organism, consisting of a cytoplasm enclosed in a cell…
