When the lac operon controls the expression of proteins in the E.coli cell that can break down lactose into two sugars, glucose and galactose. When lactose is present, it binds to the repressor that typically sits on the lac operon, changing the repressor's conformation such that it can no longer bind to the lac operon. Because of this, RNA polymerase can now transcribe the gene into mRNA, <span>which in turn is translated into the proteins that can break down lactose.</span>
Answer:
The correct answer is<u> DNA has coded instructions for making proteins, and RNA translates the code.</u>
Explanation:
We can understand this answer with the help of concept of central dogma. Central dogma is the flow of information from DNA to mRNA (transcription) and then decoding the information present in mRNA in the formation of polypeptide chain or protein (translation). Functionally, DNA maintains the protein-encoding information, whereas RNA uses the information to enable the cell to synthesize the particular protein.
Answer:The target cells of neurons include other nerve cells in the brain, spinal cord, and autonomic ganglia, and the cells of muscles and glands throughout the body.

Answer: • Most prokaryotes lack well-defined organelles. They can move from one place to another using cilia.
• The presence of peptidoglycan in their cell walls allows them to be visible on staining.
Explanation:
A prokaryote lacks a nucleus that's enveloped enclosed. Also, most of them doesn't have well-defined organelles.
The presence of peptidoglycan in their cell walls allows them to be visible on staining and they can move by using cilia.
