besides just repetition. For this exam, I am going to try concept maps (I have a difficult time with big pictures) maybe something more visual will help me remember where things go. I am still going to use Khan Academy and the modules because they make the most sense to me, because I can slow them down
student to see what DNA looks like on a macroscopic scale. DNA is extremely small, and thus understanding what DNA looks like on a macroscopic scale is important for biology students. The DNA of a eukaryotic cell is tightly bound together with a network or proteins. The DNA wrapped around certain proteins called histones form nucleosomes which could be described as beads on a string. Other proteins stabilize and support these spools, making a complex network of DNA coils and proteins called chromosome
Has anyone seen the 1993 movie, Groundhog Day? Well this movie is about a guy who wakes up to the same day every morning. Every day is the same day, life doesn’t go one and no one actually seems to care, he’s the only one who sees the difference. Well in England, a 38 years old married dad is currently living, practically the same thing. Except that time passes by but he always thinks that it is March 14, 2005, even after a decade. This man, called WO by his physicians, was in the British army
mitochondria and bacteria is achieved by using three large protein complexes, composed of several polypeptides
molecules. Anabolism is the process of storing energy by putting macromolecules together through dehydration synthesis reactions, where water is released to create a bond. Macromolecules are made of smaller molecules and have a specific function in the cell. Energy is stored in the bonds that make up the macromolecule. Catabolism is the breaking down of a macromolecule to release energy and make smaller molecules to be used for other macromolecules. Catabolism is normally
determine what percentage of the histidines in a protein will likely be protonated (the acid form) at a pH of 7.0 and at 7.4 To the clear, your answer will have two numbers. Please show your work. 7.0=6 + log [His]/[His-H] → 7-6=log [His]/[His-H] → 1=log [His]/[His-H] → 10^1= [His]/[His-H] → 1/11 (100)= about 9% for pH=7.0 7.4= 6 + log [His]/[His-H] → 7.4-6=log [His]/[His-H] → 1.4=log [His]/[His-H] → 10^1.4= [His]/[His-H] → 25.12+1= 26.12 → 1/26.12 (100)= about 3.8% for pH=7.4 Proteins sometimes
Insulin prevents protein deprivation, and plays a role in the activation of the enzymes that stores the glycogen. How and where is Insulin formed? Insulin was the very first protein to be synthesized. It is originally synthesized as a precursor molecule called proinsulin and it gave off two peptide chains.
Summer is coming and what is the fruit that we enjoy eating in summer? If you thought of watermelon then you guessed it. It is really delicious and it is refreshing us in the hot days. Although there is one thing that many people are getting annoying when eating watermelons – the seeds. Many people are first removing the seeds then eating the watermelon and that takes some time to be done and that is the reason why the hate on the watermelon’s seeds is present. Also what many people do not know is
the RNA fraction from all other macromolecules is done in a two step isolation process - phenol-chloroform. The phenol-chloroform lyses the cells, and precipitates membrane protein, lipid and chromosomal DNA through the PLG tubes. What is/are the main reasons(s) for PLG to be used in this procedure? PLG helps purify and make the yield of nucleic acids increased by up to 50% compared to other conventional organic extractions. PLG contains an intermediate density gel, which enables to eliminate interphase
it has becomefamous as a breakfast cereal cropdue to its protein and amino acid composition in both quality and quantity, which makes it an ideal food for the body. It has a multipurposeuses in the diet, food processing industries and other non-food/industrial uses.Quinoa is well-known for dietary and nutritive
