Question

Gene its nature expression and regulation

Answer 1

No content, I will still try to give a introductory answer for this type of query.

Gene are particulate elementary units of inheritance which where also called Anlagen (singular Anlage) given by Mendel and the Mendelian factors by Correns (et al in the year of 1900). They were, since then, named genes by Johannsen (et al in the year 1909). Johannsen has defined gene to be a elementary unit of inheritance which specifies the expression of a particular set or trait. Morgan has the name called gene as the smallest segment of a particular chromosome which determines a trait as well a source undergo the crossing over at the same time. Later, the workers, have found genes can be structural or regulatory in function. Seymour Benzer (et al in the year 1955) has called those structural genes to be cistrons.

Gene store and express their coded information of hereditary nature involved within the human genes. Genes can undergo replication continously so that the copies for it are transitioned and transmitted to daughter cells as well as the offspring, they occasionally undergo mutation by external and internal factors which imply to the body. The nature of the genetic material substance is innumerable of types with its material substance which not only controls the formation and expression of traits in organisms but can eventually replicate oneself and pass from one cell to another to its daughters and from one generation to the next following generation. Since, there are thousands of genes present currently in every human DNA or in an organism, the genetic material must have a lot for variety which retype and show immense amount of diversity. Only two potential biomolecules can possess this sort of variety-proteins and DNA. However, despite having a lot of variety in the genetic code, proteins cannot replicate. Replication is only present in DNA. It has also found to possess the trait forming chemicals that give rise to structure and actively take part in controlling functioning of their cells (Some of the viruses, the borderline, possess RNA as their main genetic material).

Answer 2

here is the answer -

Gene - A small unit of DNA present on chromosome which controls the trait. It's alsoknown as basic unit of inheritance.

Expression - Gene contains some information that are used to synthesise of functional gene products. These products are specific proteins. This process is known as Gene expression.

Gene Regulation - the process by which any cell regulates (increases or decreases) the production of specific gene products i.e; specific proteins then it is known as Gene Regulation.

hope it helps.
