|
|
A gene is mutated with either an insertion or deletion
|
|
|
The gene is removed from the genotype in that cell
|
|
|
The gene is passed on to the daughter cells during mitosis
|
|
|
The gene is activated and used in protein synthesis
|
Detailed explanation-1: -Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, protein or non-coding RNA, and ultimately affect a phenotype, as the final effect.
Detailed explanation-2: -Gene expression is the process by which the information encoded in a gene is turned into a function. This mostly occurs via the transcription of RNA molecules that code for proteins or non-coding RNA molecules that serve other functions.
Detailed explanation-3: -Gene expression is a tightly regulated process that allows a cell to respond to its changing environment. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
Detailed explanation-4: -Activators enhance the interaction between RNA polymerase and a particular promoter, encouraging the expression of the gene. Activators do this by increasing the attraction of RNA polymerase for the promoter, through interactions with subunits of the RNA polymerase or indirectly by changing the structure of the DNA.
