The bacterial genes are usually found in operons. Each operon comprises regulatory sequences of DNA that function as binding sites for regulatory proteins, which inhibit or encourage transcription. The regulatory proteins usually combine with small molecules that can make the protein inactive or active by altering its tendency to combine with DNA.
The four combinations of active or inactive regulatory proteins, which could be observed at any time in the cell are:
1. Active repressor, active activator,
2. Active repressor, inactive activator
3. Inactive repressor, active activator
4. Inactive repressor, inactive activator
During transcription, RNA molecules re produced, mRNA specifically.
Transcription in protein synthesis is when the mRNA is created using the
template of DNA. It is the process of transcribing DNA to mRNA which is
catalyzed by RNA polymerase. Transcription encompasses manufacturing, splicing,
and adding of caps and tales of the mRNA. All of these happen in the nucleus of
the cell.
<span>Replication, transcription, and translation are three
different terms. Replication means duplication of DNA. Transcription is the
multiplication or duplication of genetic information into mRNA and translation
is protein production through activities of ribosome.

Earth has 78% of nitrogen. So I would say Earth.
Answer: linkage
