Explain how regulation of gene expression can alter gene function.

Explanation:

The genetic information present in all cells can be  compared to a book of blueprints prepared for the construction  of a large, multipurpose building.

-At different times, all of the  blueprints will be needed, but only a small subset is consulted  during the work on a particular floor or room.

-Similarly in the case of cells all the necessary genetic information is present but but only a subset of genes is  expressed in any particular cell.

Regulation of gene expression alters the gene function in many ways.

For example in prokaryotes-

The lac operon is an  inducible operon, in which the presence of a key metabolic  substance which is lactose in this case, initiates  transcription of the  operon, allowing synthesis of the proteins encoded by the  structural genes.

In case of repressor operon: Transcription of the structural genes is controlled by a repressor  protein that is synthesized by a regulatory gene, which is also part of  the operon. It binds to the operon and blocks the movement of Rna polymerase.

i don't know why i put this, i know its not the i was just bored : p

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
