What is a genome?

Only a hundred years ago no one knew thatsuch a genome. While one German biologist Hans Winkler did not use this term in his work on interspecific amphidiploid plant hybrids. But what exactly did he mean by this word, and how is this term understood now? You will find out the answers in our article.

The concept of a "genome"

Hans Winkler first used the term "genome" in1920 year. By this word, he meant a description of the aggregate of genes contained in the haploid set of chromosomes of organisms of one biological species. According to one of the theories, the word "genome" was formed by Winkler with the fusion of two other terms: "gene" and "chromosome".

Modern science means by the word"Genome" is a set of hereditary material, which is enclosed in the body cell. That is, the genome includes biological information. It is necessary both for building and maintaining the body.

The genome of most cellular organisms, includingnumber, of a person, are built from DNA. But there are a number of viruses, whose genome consists of RNA. DNA is a deoxyribonucleic acid that stores and transmits genetic information. A RNA is a ribonucleic acid, which also contains genetic material.
