Answer:

The correct answer is C) Maltose promotes the synthesis of the maltose operon functional gene as it acts on the regulatory gene to make it a functional activator

Explanation:

Maltose promotes the synthesis of the maltose operon functional gene as it acts on the regulatory gene to make it a functional activator. The regulatory protein is not functional until maltose is present to bind to the protein. Then, in its altered form, it can bind to the operator of the operon and direct the RNA polymerase to the promoter to increase transcription.

Answer:

<u>Inducer</u>

<u></u>

Explanation:

Structural proteins within bacteria are encoded along with their functions. These are typically found in a block of genes called an operon. They undergo transcription together with the use of a single promoter sequence to form a polycystronic transcript- this allows for the simultaneous control and regulation of biochemical pathways. This is efficient as these pathways would either need to function together when "switched on" or will not be needed when "switched off". Repressors are proteins that effectively hinder translation by binding to DNA at the operator site, blocking the activity of RNA polymerase in transcription. However inducers are small molecules that can displace these, freeing up the operon for transcription and the activation of relevant biochemical pathways.

The mal operon includes genes which mediate the breakdown of the substrate maltose in bacterial cells. Maltose, called a malt sugar, is a carbohydrate compound made up of two glucose molecules joined by an α-(1,4) glycosidic linkage.

In the presence of maltose, the inducer binds to the activator. This then allows for the binding of RNA polymerase, which facilitates translation and th epr

Using two or more sentences, describe how a light microscope creates a magnified image.
a_sh-v [17]

Answer:  A microscope is an instrument that produces a clear magnified image of an object viewed through it. A microscope must be able not only to magnify objects sufficiently but also to resolve, or separate, the fine details of the object that are of interest to the viewer. In the optical microscope visible light rays, reflected from or transmitted by the viewed object, pass through a series of lenses and form an enlarged image of the object. This image is produced at the normal distance of clearest vision, which is about 10 inches, or 25 centimetres, from the eye of the viewer.
