David Daige Biol 1030H Due Date: April 1, 2016 Professor Laura Pacey Lab Report 5: Molecular Biology Techniques Abstarct The aim of this study is to accurately measure small volumes using the micropipettes and to use virtual STR and PCR programs to test the paternity of various cases. During the lab, 18uL of different volumes were successfully measured into a tubule using the micropipette. During the lab, fruit juice was accurately extracted from a solution using…

1. Write a summary of the article using your own words. Lichens are evolutionarily deep symbioses of nature that are widespread and diversed. It is recently discovered that in addition to being composed of fungus and alga, as known by many, lichens are also composed of varying amounts and species of basidiomycete yeast. This discovery is made when Dr. Spribille and his colleagues analyze two species of lichen that are similar in genetics of fungus and alga but different in appearance,…

Preimplantation genetic diagnosis (PGD) is a method used prior to implantation to help identify genetic defects within embryos created through in vitro fertilization. This procedure is used to help prevent particular diseases or disorders from being passed on to the infant (American Pregnancy Association). Science cannot only help couples that are unable to have babies, but it can help them have babies they want. However, where should the line be drawn for modern reproductive medicine? (Kalb…

seem to be a cell or made up of cells, which is a very vital characteristic of life. They do contain DNA but do not contain a cytoplasm or organelles which are both typical of a cell. Due to this they should not be considered cells or alive until further proof can be revealed.…

into surrounding tissue (121). Key players that help mediate necrosis include ROS, Calcium ions, poly-ADP-ribose-polymerase (PARP), and lysosomal proteases (888). PARP is an enzyme that is responsible for repairing DNA damage, such as strand breaks. Cells that have undergone a traumatic cellular insult typically have damaged DNA. PARP will deplete cellular ATP in an attempt to repair the massive damage to DNA. Several proteases are activated by increased cellular calcium ion concentration that…

The intricate workings of the mind define how a person is able to engage his or herself in an activity that requires a lot of concentration and focus, memorizing fine details about surroundings, or even solving inopportune problems. What is fascinating about this process is the idea that only a chunk of the information a person processes everyday will be retained from the conscious part of the mind, leaving the remaining information to be processed unconsciously. The irony is defined when…

The perusal and review of twin, adoption, and family studies allows us to understand how the combination of biology and environment shapes us all. Some aspects of personality are linked to genes and have a biological basis, but it has allows been hard to separate biological basis of behavior from an environmental basis of behavior. Twin studies are a vastly important tool in dissecting the nature versus nurture argument. Pros of twin studies are that identical twins otherwise known as…

carry out. Small part of the cell which is called organelles, they have been adapted to carry out certain function and this can be more than one. Organelles are found in eukaryotes and they are always surrounded by protective membrane. Mitochondria which is the organelle it acts like a digestive system because it takes in all the nutrients, breaks them down into smaller molecules and it creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular…

Scientific technology today has made many advancements. Humans have more at their fingertips than ever before, including the option to design their own baby. A common technique for doing so is known as in vitro fertilization. This technique involves combining the sperm and eggs into a petri dish and then inserting the fertilized eggs into the female’s uterus. Other methods include injecting specific sperm directly into the fallopian tubes, this sperm can be provided by either the parents…

There are four types of interactions that stabilize a protein and give it structure at the tertiary level. Hydrophobic interactions are nonpolar molecules, they generally have a long chain of carbons that do not interact with water molecules. RGroups prefer to interact with each other internally and away from water (Wolfe, G. (2000). Thinkwell biochemistry - 2.7.4 Tertiary Structure). This interaction contributes significantly to the folding and shaping of a protein. Hydrophobic interactions…
