The cell membrane The cell membrane is whole to the cell (it is especially around the core and the core God cell body) and especially if a protection. Through the pores in the cell wall can still find out exchange of substances between the cell and the body and between one or more than one [...]

The germ cells The hereditary material is pass it on to posterity. Men and women in the reproductive cells produce respectively the testes and ovaries. In these bodies are haploid germ cells produced. This means that each of the chromosomes of only one instance is present, so there are no homologous chromosomes. The other body [...]

What is cloning? Cloning is to create a genetically identical copy of an individual. Cloning is not new in itself. Who are identical twins are natural human cloning. Typically, the children of the same parents a different look. They are the same as in the fact that half of their genes of their father and [...]

A useful role to decipher the DNA? In addition to the huge amount of work that needs to be done, you can ask yourself if scientists have nothing better to do. In fact, it costs a great deal of time and money. People who know something of genetics, are familiar with the fact that of [...]

Pheromones Pheromones are chemicals that serve as a means of communication between individuals of the same suit. Although these substances in humans are present, they work in animals from strength to strength. By vomeronasale organ (VNO/vomeronasal) where animals pheromones. This detection system for pheromones is separate from the more developed nose, which later in the [...]

Enzymes bind themselves to the substrate (so called to convert the substance or substances). By that binding small changes to the substrate molecules, making them easier to respond (split or parts). The enzyme is then again just usable. That is why it is also important to the protein form that you do not change. When [...]

The chromosomes In each cell of an organism is a quantity of genetic material that behavior, and appearance of the cell. From now on I shall confine myself to the enhancement of human cell, there are, however, major agreements with other organisms. In the cell nucleus of each cell in the body are chromosomes present [...]

The transcription The bases of the DNA coding for a protein that must be made in the cell. Each of the four groupings of three bases encodes a single amino acid. Such a group of three bases is also known as a codon. DNA is not directly read. In a process called transcription is carried [...]

The appearance is like a key engine of the law. The significance of this is not that the single new discovery. For years, genes play a central role in science and in fact in all aspects of life of all living organisms. They manage our natural appearance, but also the impact that they wield on [...]
