Answer:

c. several genes, next to each other in prokaryotic DNA, that are transcribed as a single piece of mRNA

Explanation:

An operon is a functioning unit usually found in prokaryotes. It contains a group of genes under the control of same promoter such that when transcription occurs, these genes are transcribed together to form a single mRNA product. So the genes of an operon are either transcribed together or not transcribed at all. The mRNA formed is usually a polycistronic mRNA i.e. it codes for more than one protein.

Operon has three parts: promoter, operator and structural genes. Promoter enables the structural genes to get transcribed. Operator in turn controls promoter. It's a segment of DNA to which the repressor molecule binds.

Sveta_85 [38]

Answer:

C. Simple diffusion

Explanation:

Simple diffusion from a high to low concentration is the most direct method that ions or molecules can move across a cell membrane.

Through this method, no proteins are required for transport, and no energy is used.

The ion or molecule being transported directly moves across the cell membrane, without any other factors involved.

So, the correct answer is C. Simple diffusion
