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
You put sand in the furnace
Answer: A
Explanation:
UAC = Tyr
UCU = Ser
ACC = Thr
So the polypeptide chain corresponds to A

What amino acids, fatty acids, and sugars (monosaccharides) have in common is that they are made of carbon, oxygen, and hydrogen which is option B.
Amino acids are the basic structural units of proteins. Each amino group (-NH₂) and a carboxyl group (-COOH) in its molecule. Thus, from the molecular structure of an amino acid, the carboxyl group of the molecule contains carbon, oxygen and hydrogen elements.
Fatty acids are commonly found in lipids ans are made up of long chain alkanoic acids of general formular, RCOOH where R contains about 10 to 18 carbon atoms. the terminal -COOH group contains carbon, oxygen and hydrogen elements.
Sugars (monosaccharides): they are naturally occuring organic compounds containing carbon, hydrogen and oxygen, with the hydrogen and oxygen present in the ratio of 2:1. The general formula for monosaccharides is C₆H₆O₁₂.
Therefore, amino acids, fatty acids, and sugars (monosaccharides) have carbon, oxygen, and hydrogen in common.
