I guess the point about increasing level of oxygen is most correct......
The bacterial cell membrane can be targeted for killing it. Inhibition of the synthesis of the components of cell wall will not allow the bacteria to grow.
The genetic material of the bacteria- DNA can be targeted. When DNA is cleaved, or damaged, then the bacteria will die.
The cellular components of the bacteria may be targeted. If a organelle, or a component is responsible for production or transport of proteins, and it is targeted by anti-bacterial compound, then protein synthesis machinery of bacteria will stop working, and it will not be able to perform a number of functions, and eventually die.
Answer:
Transcription is the second step in central dogma of molecular biology. First step is replication, second is transcription, and third is translation.
In the transcription phase, DNA, which is already replicated, is transcribed to mRNA which is required to make proteins in the translation phase. The root words say it is a combination of "across" and "write". This means that DNA is going to be written in a new language "mRNA". So, this term has been used in biological process because it is the re-writing across the whole DNA to make a completely new strand of mRNA.
Hope it helps.
