Molecular mass

lower gradient. The solutions 0.40mol/L, 0.60 mol/L, 0.80 mol/L, 1.0mol/L lost mass after diffusion. This is due to there being a higher concentration inside of the potato cells than in the glucose solution. The transport went to the glucose solution outside of the potato, which made it hypertonic osmosis. Through the information from our graph, we can gather information creating conclusions. In the change in mass, there is a specific point where the results become negative, or the point of…

Introduction The human cell consists of three parts; the plasma membrane, the cytoplasm, and the nucleus. The plasma membrane is the outer boundary of the cell, it separates two major fluid compartments- the intracellular fluid and the extracellular fluid, and plays a key role in cell transport. Cell transport is the movement of materials across a selectively permeable membrane, and this process can occur in two ways; passive transport and active transport. Passive transport allows substances to…

Microbiology Conjunction Conjugation is the course by which one bacterium transfers genetic material to another through direct interaction. It can be defined as the direct transfer of DNA form one bacterial cell to another bacterial cell. The donor is F+ and the recipient is F-. they are attached through a conjugal bridge. The pilus then attractions the two separate bacteria together. Now, the donor bacterium transfers genetic material to the recipient bacterium. During the process of…

from an artist named Andrew Leicester who created the G-Nome on the Molecular Biology Building in 1992 and many other artifacts as part of the G-Nome Project. The G-Nome comes from two different words: Gnome (a dwarf-like creature that usually guards precious treasure) and genome (a scientific term for a complete set of chromosomes). There are four G-Nomes, each twelve feet terra-cotta structures on each corner of the Molecular Biology Building. The G-Nome is an abstract piece of art. It is not…

The molecular ruler, as seen in Figure 1, did not produce bands that were as bold as the bands produce by the PCR products. This most likely occurred due to the sample not being loaded correctly into the sample well. Some of the contents may have diffused out…

Question 1: a) A: Promoter B: Splice site C: 5’ UTR D: Start codon E: Stop codon F: 3’ UTR b) The sum of the exons and introns (all in kilobases) (1.2+8+0.7+27+0.4+11+3.1) = 51.4 kb. c) The sum of the exons (all in kilobases) (1.2+0.7+0.4+3.1) = 5.4 kb. d) RNA Protein Truncation mutation in exon 2 Same length, same amount of RNA produced. Shorter in length (due to earlier stop codon), same amount of protein produced, usually changes the protein to non-functional, though not always. 3bp in…

To examine the DNA, a gel electrophoresis test needs to be run. The first step of gel electrophoresis is to set the gel, which is made of agarose. Agarose is used to separate DNA molecules, and acrylamide is used to separate proteins. The gel starts off as a liquid, which is poured into a molding tray and after it sets, it will turn into a solid. Next .all of the DNA needs to be collected and copied with a Polymerase Chain Reaction, PCR, which is vital to the success of the gel process because…

XAL2, a MADS-box gene, studied by Pérez-Ruiz et al. (2015), is preferentially expressed in the roots, with less expression in the rosette leaf, stem, and cauline leaf. It is not present during the vegetative meristem stage; as XAL2 expression appears initially in the inflorescence. Following the inflorescence meristem stage into floral meristem stage, XAL2 expression increases significantly in order to regulate floral transition. Although XAL2 was found to have higher expression in the roots,…

The nitrogen containing BP, Zoledronic acid, is one of the most commonly implicated drugs in BRONJ cases due to its higher potency and multimodal effect on bone remodeling and oral mucosa. 20-22 ZA induced BRONJ models are known to show classical BRONJ lesions with macroscopic features of bone necrosis, soft tissue inflammation and sequestration in various animal models, ranging from rats to large animal models like sheep. 16,17,23 However, the exposure of bone to the oral environment, either…

Title: Which Antibiotics Kill the Most Bacteria? Caroline Gorman April 2, 2016 HB bl. 6 Purpose: The purpose of this lab was to determine which of five common antibiotics would kill the Rhodococcus rhodochrous bacteria. Hypothesis: Out of the five tested antibiotics, doxycycline will kill the most Rhodococcus rhodochrous because it is generally used to treat mild infections. This will be tested by spreading the bacteria on agar in a Petri dish and adding a small amount of each antibiotic…
