Breathing is the exchange of gases between animals & the environment.
RNA polymerase binds to the lac promoter and begins transcribing
the stretch of DNA to messenger RNA.
Therefore, in other words, the stretch of DNA is expressed. The DNA sequence of
the lac promoter 'signals' where the RNA
polymerase will bind and where transcription
will begin. Promoters are found upstream of a gene to be transcribed.
Answer:
ions?
Explanation:
If it picks up or loses an electron, it becomes electrically charged and highly reactive. Such electrically charged atoms are known as ions. ... In an effort to achieve equilibrium, the atom emits particles in the form of radiation until the nucleus is stable. Such unstable atoms are said to be radioactive.
