In this article we will discuss about the mechanism of eukaryotic gene expression, particularly in humans. 1. In multicellular organism, each cell expresses a subset of its genes. 2. A cell expresses different genes depending on its growth state or environment. 3. Sometimes gene transcripts are spliced differently in different cells. 4. Each gene carries not only structural information but [...]
In this article we will discuss about the features and effects of gene. Essential Features of Gene: Prior to 1940, recombination was not believed to occur within genes. The genes in a chromosome were considered analogous to beads on a string. Recombination was believed to occur only between the beads or genes. The gene was not considered subdivisible. But, on [...]
In this article we will discuss about the functional activities of gene in action. The functional activity of these genes which are needed in all cell types are known as house-keeping genes and those who are active or the activities of those genes are found only in some specialized cells are known as luxury genes. But from the point of [...]
