Actinomycin is used only in research applications or cancer treatment because it is active against both prokaryotic and eukaryotic cells.
<h3>How does actinomycin work?</h3>
- Actinomycin D inhibits RNA synthesis in both prokaryotic and eukaryotic cells thus blocking transcription.
- Actinomycin was first isolated from <em>Streptomyces antibioticus</em>.
- These bind to the DNA at the site of transcription initiation complex and prevent the activity of DNA dependent RNA polymerase.
- By blocking the metabolic machinery of cells (RNA synthesis), actinomycin prevents the growth of cells. Therefore used in cancer treatment to prevent uncontrolled proliferation of cells.
- As it can also act on eukaryotic cells so it is not used as an antimicrobial drug as it can harm the cells of our body.
- However it can be used in research to prevent microbial growth in petri plates.

Lack of clean water is able to complicate health. This could easily cause dehydration in children and adults. If someone is dehydrated, they won't be able to function properly and if they stay like this for long, this can cause a risk of death. Lack of clean water can easily turn into hygiene problems because the child wouldn't have a way to clean themselves or even do something as simple as washing their hands. This can transfer many bacteria only making the children catch illnesses. This, therefore, would prevent them from learning. This also goes for teachers because if the teachers do not have proper hygiene, they won't be able to teach. Once again this would affect children as well because children wouldn't have anyone to learn information. This would result in a bad education.
