Which nucleic acid moves the code for protein synthesis from the nucleus to the ribosomes?

Which occurs during translation?

Which describes a promoter?

Which summary below correctly describes what occurs during transcription?

Only the proteins that the bacteria Escherichia coli (E. coli) needs are synthesized at any given time. For example, when lactose is available in the environment, E. coli will express the lac genes that allow it to break down lactose to obtain energy. When lactose is not present, these genes are not expressed.Which prevents the lac genes in the DNA of E. coli from being expressed most of the time?
