Arginine, Leucine, Lysine, and Valine are all amino acids. Lysine and Arginine are both under the category of charged polar amino acids, where they exhibit a positive charge. Leucine and Valine are both uncharged non-polar amino acids, and, as such, are hydrophobic.
What would happen to a separation of amino acids if the solution pH was changed to pH 10 or 3?
Could this help to separate and identify amino acids that are similarly charged at pH 7?
Define the terms: Autotroph and heterotroph. Describe the differences between photoautotrophs and chemoautotrophs and chemoautotrophs and heterotrophs with regard to their energy source and their role in ecosystems. Give examples for each kind of ..
In a nondividing cell such as a liver cell, why must the flow of membrane between compartments be balanced, so that the retrieval pathways match the outward flow? Would you expect the same balanced flow in a gut epithelial cell, which is actively ..
Describe the mechanisms used by transposable elements to move between DNA molecules (cut and paste, replicative, retrotransposable elements)?
A lethal mutation occurs in a bacterium, rendering it incapable of replicating it's chromosome. Because of this mutation, DNA synthesis produces many short fragments of DNA that have RNA sequences at their 5' ends.
What is the function of amino acyl tRNA synthetases, AND how many different kinds of this enzyme are there?
How do protists transport wastes and ions.

a sponge is an animal with three different types of cells. it is an aquatic invertebrate that has no true tissues or
Sanger-based sequencing needs very specific DNA and primer concentrations for optimal performance. For template DNA like plasmids, DNA needs to be at a concentration of 50ng/ul in 10 ul.
Viruses are the ultimate scavenger-a necessary consequence of their small genomes. Wherever possible they make use of the cell's machinery to accomplish the steps involved in their own reproductions.
Identifying plants is a great way to learn plant anatomy and learn about plants. There are many field guides that can help you identify plants, but one of the easiest ways to identify plants is to use a dichotomous key.
