Before discussing the topic of genetic diversity‚ it is imperative that you‚ the reader‚ can get an understanding of what all topics and points of focus that is taken into consideration when discussing genetic diversity. This includes a brief history as to how this came about‚ and what components allow this process to occur. Genetic diversity can be a complicated‚ yet interesting topic to cover. From the name of the process of genetic diversity‚ it can be inferred that this deals with genes and

transfer. • Methyl group: a chemical group consisting of a carbon bonded to three hydrogen atoms. The methyl group may be attached to a carbon or to a different atom. • Macromolecule: a giant molecule formed by the joining of smaller molecules‚ usually by a dehydration reaction. Polysaccharides‚ proteins‚ and nucleic acids are macromolecules. • Polymer: a long molecule consisting of many similar or identical monomers linked together by covalent bonds. • Monomer: the subunit that serves as the building

1. Describe the fluid-mosaic model of a plasma membrane. Discuss the role of the membrane in the movement of materials through it by each of the following processes: a. Active transport b. Passive transport The plasma membrane is a semi permeable barrier that separates the inside of the cell from the outside environment. The plasma membrane is made up of carbohydrates‚ cholesterol‚ proteins‚ and a lipid bilayer‚ or double layer of lipids. The plasma membrane may be known as a fluid mosaic

Discussion: The liver homogenate was expected to have the highest amount of protein concentration‚ DNA concentration‚ and total glucose when compared to the other homogenates. The liver was the biggest organ in B. taurus and it carried out numerous functions such as producing bile‚ synthesizing proteins for blood clots‚ and recycling old red blood cells. The liver ended up containing the most DNA concentration‚ but it was surpassed in protein concentration by the kidney. The protein concentration

Bacterial Biology █ BRIAN D. HOYLE An understanding of the fundamentals of bacterial biology is critical to bacteriologists and other forensic investigators attempting to identify potential biogenic pathogens that may be exploited as agents in biological warfare or by bioterrorists. Fundamentals of Bacterial Biology Bacteria are one-celled prokaryotic organisms that lack a true nucleus (i.e.‚ a nucleus defined by a membrane). Bacteria maintain their genetic material‚ deoxyribonucleic

used to match to each element of the meal. Along with the lab data‚ our prior knowledge also led us to our results. We were able to determine that Unknown A is the Sprite due to the fact that every test was negative except for simple sugars‚ a macromolecule that the majority of sodas contain. We determined that Unknown C were the fries because of the starches and lipids present. Fries come from potatoes‚ which are plants‚ which make starches‚ meaning that fries contain starches‚ furthering our proof
