Answer:
Nucleus
Explanation:
In eukaryotic cells, the nucleus is a membrane-bound structure that contains the genetic material, which is expressed in response to cell stimuli (i.e., environmental stimuli). This genetic material consists of genes that are expressed in response to cell signaling events. For example, the transcription factors that are found in the cytoplasm are activated after receiving a signal from receptors localized in the cell membrane, when these membrane receptors bind to specific signaling molecules. Subsequently, these transcription factors are translocated into the nucleus to interact with DNA promoter regions in order to activate the expression (transcription) of target genes capable of responding to an environmental stimulus.
They are termed broad-spectrum antibiotics.
<h3>What are antibiotics?</h3>
Antibiotics are drugs that have the capacity to either inhibit the growth of or kill bacteria and some other microorganisms capable of causing diseases.
Antibiotics are of 2 types:
- Narrow spectrum antibiotics
- Broad spectrum antibiotics
Narrow spectrum antibiotics are effective against a very narrow range of bacteria. They are very specific in their targets.
Broad spectrum antibiotics, on the other hand, are effective against a broad range of bacteria. They can be referred to as multipurpose antibiotics. They do not only eliminate target pathogenic bacteria.
