A researcher has developed a drug that kills cells by preventing transcription. The most direct effect of the?

Question

drug is that is prevents the cell from

Making new DNA
Making new proteins
Exporting substances from the cytoplams
breaking the lungs down in the cytoplasm

Answer 1

It prevents the cell from making new proteins, which are necessary for the survival of the cell. This is why the other options don't work: The order of DNA synthesis is Replication, Transcription, and Translation. Therefore, since replication takes place first, new DNA is formed.. however the process is stopped at transcription, where DNA is converted into RNA and then eventually into amino acids (building blocks of proteins) through translation.

and the other two options are just silly lol

Answer 2

This is an interesting question. The first and most obvious answer is 'making new porteins', because without transcription, you get no new mRNA

However, this doesn't mean that the cell can't produce any protein. mRNA lifetime is regulated by several things. What I expect you would see is a significant falloff in protein production followed by eventual cell death; it certainly wouldn't be an immediate death, but it would almost certainly be necrotic as opposed to apoptotic.

Answer 3

Making new proteins - plenty of drugs already inhibit transcription (natual and non-natural), like alpha-amatin secreted from a naturally occuring mushroom known as "death cup"

Answer 4

making new proteins
