Different Kinds of Chromatography

Chromatography is a technique used to isolate the various components of a mixture and this makes its application in analysis of biomolecules very important. It is used to separate and analyse the complex DNA sequences and other compounds, and also the concentration of the samples. There are many types of chromatography used in the study of biomolecules which range from DNA/RNA to recombinant proteins and antibodies. Here are some types of chromatography that you should know about.

High Performance Liquid Chromatography

Small particles and High pressure is required to carry out this type of liquid chromatography. HPLC has many forms and its application revolves around drug analysis and other forensic applications. There are forms of HPLC which specifically deal with enzymology and purification of other biomolecules.

An In-Depth Look at Mitosis and Meiosis

Mitosis and Meiosis are both cellular processes in nature which result in the division of cells and formation of new life. Mitosis involves the division of a cell into two identical cells, each containing the exact genetic makeup (genome) in their chromosomes as the original cell, but go through differentiation during a eukaryote organism's development in order to accommodate for the different cells that the body requires. Mitosis takes place in both single-celled organisms, being the method in which they are able to reproduce, and also in eukaryote somatic (body) cells, allowing them to proliferate and repair damaged tissue. Meiosis on the other hand only occurs in the sex cells of organisms and is the method by which sex cells produce gametes for sexual reproduction.

These sex cells are called germ cells, which when divided are termed gametes. Gametes are sperm in males and ova in females. 

Biology Review: Proteins and Enzymes

Proteins

Proteins are long chains of amino acids joined by peptide bonds that fold up into complex three-dimensional structures.

The functions of proteins are so diverse and important that almost every function of every living organism depends on proteins.

This helps explain why evolutionary biologists tend to believe that protein synthesis preceded the evolution of the first cells.

In cells, proteins account for about half of the dry mass.
