Answer:

The correct option is C. A virus contains RNA or DNA in a protein coat.

Explanation:

Viruses can be described as tiny particles which are able to incorporate their genetic material into a host. Many viruses can be destructive to the host cells.

The structure of a virus includes DNA or RNA which is enclosed in a structure known as an envelope or capsid. The envelope or capsid is made up of proteins. Some viruses also have a tail.

The capsid of a virus usually remains outside the host cell and it injects its viral genome into the host cell. The DNA or RNA o the virus then incorporates in the host cell.

A is a DNA sequence where RNA polymerase binds and begins the process of transcription. A is a DNA sequence that binds regulator
WARRIOR [948]

<u>Answer:</u>

A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.

<u>Explanation:</u>

Background Knowledge:

DNA contains genes which is a particular segment of DNA. A gene usually has regulatory regions and a structural region.

Promoter: The regulatory region located to the 5 prime end of coding strand of the gene which is called as promoter that controls the binding RNA Polymerase during transcription.

The Terminator is the other regulatory region, located to the 3 prime end of coding strand of the gene. The terminator region causes RNA polymerase to stop transcription.

Structural region is the region present between the promoter and terminator.

Answer of the question is:

A is a DNA sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.
