What is mitosis? Mitosis describes the process of cell division. Cell division begins with the doubling of DNA and ends with the strangulation of the new cell. Thus, two identical daughter cells are formed from a mother cell, which contain the same genetic information. During the entire mitosis process, both the mother cell and the … Mitosis – Simply explained!
What are the stages of mitosis? The cell cycle, which is responsible for cell division and thus also for cell proliferation, can be divided into interphase and mitosis. In interphase, the DNA is doubled and the cell is prepared for the upcoming mitosis. This phase of the cell cycle can be of varying length and … What are the stages of mitosis? | Mitosis – Simply explained!
Duration of mitosis Mitosis lasts on average about one hour, so that one can speak of rapid cell division. Compared to interphase, mitosis takes relatively little time. In addition, the interphase can last from several hours to several months or even years, depending on the cell type. The G1 – and the G0-phase in the … Duration of mitosis | Mitosis – Simply explained!
What is the difference between mitosis and meiosis? Both mitosis and meiosis are responsible for nuclear divisions, although both processes differ in their sequence and results. Mitosis is the process by which two identical daughter cells with a double (diploid) set of chromosomes are formed from a mother cell. In contrast to meiosis, only one … What is the difference between mitosis and meiosis? | Mitosis – Simply explained!
Heredity, genes, genetic fingerprint Definition DNA is the building instruction for the body of every living being (mammals, bacteria, fungi, etc.) It corresponds in its entirety to our genes and is responsible for the general characteristics of a living being, such as the number of legs and arms, as well as for individual characteristics such … Deoxyribonucleic acid – DNA
DNA bases There are 4 different bases in the DNA. These include the bases derived from pyrimidine with only one ring (cytosine and thymine) and the bases derived from purine with two rings (adenine and guanine). These bases are each linked to a sugar and a phosphate molecule and are then also called adenine nucleotide … DNA bases | Deoxyribonucleic acid – DNA
DNA Replication The goal of DNA replication is the amplification of existing DNA. During cell division, the DNA of the cell is exactly duplicated and then distributed to both daughter cells. The doubling of DNA takes place according to the so-called semi-conservative principle, which means that after the initial unravelling of the DNA, the original … DNA Replication | Deoxyribonucleic acid – DNA
DNA sequencing In DNA sequencing, biochemical methods are used to determine the sequence of nucleotides (DNA base molecule with sugar and phosphate) in a DNA molecule. The most widely used method is the Sanger chain termination method. Since DNA is composed of four different bases, four different approaches are made. Each approach contains the DNA … DNA sequencing | Deoxyribonucleic acid – DNA
Research goals Now that the human genome project has been completed, the researchers are trying to assign the individual genes to their significance for the human body. On the one hand, they are trying to draw conclusions about the development of disease and therapy, and on the other hand, by comparing human DNA with the … Research goals | Deoxyribonucleic acid – DNA
Examples of epigenetics Epigenetic examples can be observed in every person in old age. Many diseases are nowadays attributed to epigenetic changes, among other things. A typical example of visible epigenetics is the so-called “X-inactivation”. Here, an X chromosome is completely silenced by epigenetic processes. This mainly affects women who have two X chromosomes. One … Examples of epigenetics | Epigenetics
What role does epigenetics play in depression? Epigenetics plays a particularly important role in the development of psychiatric diseases. The activation and inactivation of certain gene sequences can lead to diseases such as depression and schizophrenia. Age and environmental factors that lead to altered epigenetic processes are probably also responsible for this. Mental diseases are … What role does epigenetics play in depression? | Epigenetics
Definition Epigenetics is a broad and comprehensive biological discipline that deals with genetic functions that go beyond the mere sequencing of DNA bases. The genetic material consists primarily of DNA strands that are formed from differently arranged base pairs. In every human being there are differences in the order of the base pairs, which in … Epigenetics
