BSC1010L SectionU42 The effect of Control Plasmid and Plasmid Lux in Bacterial Transformation Vanessa Louis PID: 4709178 Lab Partners: Patrick Abaunza Raquel Alespeiti Robert Lugo Date Performed: 31 October 2014 TA: Reinier Llorca Abstract According to The General Biology I Lab manual, involved in Gene expression are two complex cellular pathways, each being subjected to regulation (Alberte et al., 2012). The first pathway is the synthesis of an RNA molecule from a DNA strand.…

initiation, initiation, elongation, and termination. A basic transcription process starts out with a start codon where translation begins by ribosome initiation. These ribosomes move through the mRNA to generate new subunits of proteins. tRNA and mRNA sequences interact through codons and anticodons and tRNA is what brings amino acids for the use of the ribosomes in translation; therefore, amono acids continue to be made as long as there is availability of resources until a stop codon is hit…

action of azithromycin is inhibiting bacteria from developing through interfering with protein synthesis. While this mechanism of action is similar to the one of gentamicin, it differs in the fact that azithromycin binds 50S subunit of the bacterial ribosome. Even though this contributes to prevention of the translation of mRNA, the drug’s mechanism of action does not affect the synthesis of nucleic…

(Tetracycline, n.d.) It works by inhibiting growth of bacteria, by binding to the bacterial ribosome, this stops the addition of amino acids from the growing of peptides which results in the inhabitation of protein synthesis. Although Tetracycline can stop a large amount of illnesses, it can cause nausea, vomiting and diarrhoea, however in young…

Plasmodium is a parasite with over 100 species, but only four directly affect humans(“Malaria Parasites”). This parasite affects the circulatory system, or cardiovascular system(Coolidge-Stolz 78). Even though it’s microscoping in size, it can cause a lot of damage. It has many things that structure it, and some are even in common with animals (“Structure of Plasmodium Merozoite”). The parasite gets into the body from mosquitoes and infects the bloodstream(“Plasmodium”). The plasmodium parasite…

cristae; this increases the surface area of the membrane and maximizes cellular respiration output. The region between the two membranes is the intermembrane space. Inside the inner membrane is the mitochondrial matrix, and within the matrix there are ribosomes, other enzymes, and mitochondrial DNA. The mitochondrion is able to reproduce and synthesize proteins independently.…

that does not require oxygen for its metabolism and is capable of growth in the absence of it (Cowan & Talaro, 2009, p. 185). S. pyogenes is a prokaryote because it is an organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops (“Classification,” n.d.). S. pyogenes is a gram-positive bacteria cocci in chains and it causes many diseases in humans, making it parasitic…

Serratia marcescens is one of many species that have been shown to cause infection even though it was once considered as non-pathogenic. Therefore, it is crucial that we find an effective method of controlling these bacteria. Previous studies have already shown that aminoglycosides such as Streptomycin are effective against S. marcescens, but it is also necessary to administer the antibiotic at certain concentrations for minimizing bacterial growth. In this experiment, we attempted to find a…

Prokaryotes There are two types of organisms based cell types: Prokaryotic and Eukaryotic. Prokaryotic cells are divided into two parts: Bacteria and Archaea. Prokaryotes are much smaller than eukaryotes. Prokaryotes contain a single loop of chromosomal DNA which is stored in nucleoid. Eukaryotes DNA is found on tightly bound and organised chromosomes. Genetic expression is the process where genotypes coded in the genes are displayed by the phenotypes of the individuals. The DNA is then copied…

centre of the cell, it controls how the cell develops and how it reproduces. DNA is the genetic makeup of a cell, organ and body systems, the DNA in a cell is held and organised into discrete chromosomes by the nucleus. The nucleus also creates new ribosomes by extracting Ribosomal ribonucleic acid, (rRNA) which is synthesised instructions from the DNA and putting the rRNA with assembled proteins. Together the rRNA and…
