<span>An electric current is running through the gel in the electrophoresis with positive pole on the bottom. So, only negatively charged particles can migrate through the gel in the electrophoresis. </span>Since DNA is negatively charged, it migrates toward the positive pole of the gel. This characteristic enables DNA to move through the gel.
I found this info if this is what you need link http://www.answers.com/Q/What_are_the_functional_groups_of_amino_acids
Two functional groups are found in all amino acids. These functional groups are the
amino group
(-NH2) and the
carboxyl group
(-COOH). The hydrogen atom of the carboxyl group can be broken off quite easily; this gives amino acids their acidic properties.
Function of amino acids?
Heat and Energy, Growth, To defend against disease, and to Repair bodily cells are the functions of amino acids/ proteins.
Amino acids contain a carboxyl group?
Yes, amino acids contain: 1) an amino group (-NH 2 ) 2) a central carbon and variable side group 3) a carboxyl group (-COOH)
What is the function of amino acids?
Amino acids are nitrogen-containing molecules that serve vitalfunctions in your body. Twenty-two amino acids occur in nature, and20 of these are incorporated into proteins and other moleculeswithin the cells and tissues of plants and animals. According toscientists at the University of Arizona, your body can synthesize10 of the amino acids you need, while the other 10 must be acquiredfrom your diet. Amino acids that cannot be produced within yourcells are called essential amino acids. http://www.livestrong.com/article/426255-what-is-the-function-of-amino-acids-in-the-human-body/
What is the amino group on an amino acid?
The amino group is present at one end of the amino acid and is represented by the chemical formula NH 3 The region on the amino acid that contains the amino group is called the amino terminal
Amino acid function?
Amino acids are basically known as the building blocks of protein.The function of an amino acid is primarily to build proteins.
Answer: A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1).
