What is gene expression?
Q: What is gene expression?
A: Gene expression is the process by which the heritable information in a gene is made into a functional product, such as a protein or RNA.
Q: How is gene expression achieved?
A: Gene expression is achieved through a process where DNA is transcribed into RNA, which is then translated into proteins.
Q: What do proteins do in a cell or organism?
A: Proteins make many of the structures and all the enzymes in a cell or organism.
Q: What is gene regulation?
A: Gene regulation is the process by which genes are switched off and on, which controls cell differentiation and morphogenesis.
Q: How can gene regulation serve as a basis for evolutionary change?
A: Gene regulation can serve as a basis for evolutionary change by controlling the timing, location, and amount of gene expression, thereby having a profound effect on the development of an organism.
Q: What is pleiotropism?
A: Pleiotropism is the phenomenon in genetics where the expression of a gene may vary a lot in different tissues.
Q: Which stages of gene expression can be modulated?
A: Both the transcription and translation stages, as well as the final folded state of a protein, can be modulated during gene expression.
