The correct answer of the given question above would be option A. The statement that best describes one property that helps to ensure the reliable transmission of genetic information in living organisms is that RNA uses a nucleotide base called uracil to distinguish itself from DNA. Hope this is the answer that you are looking for.

#1. Typical United States weather patterns show the continental polar air mass moving south toward the Gulf of Mexico. Why does this air mass movement happen?
C) The polar air mass moves south to replace the rising maritime tropical air mass.
#2. Running a mineral across a porcelain plate to see the color it leaves behind on the plate may be described as testing for D) streak.
#3. D. Carbonization preserves soft tissues of plants or animals as a thin carbon film, usually in fine-grained shale sediments.
#4. We can divide natural resources into two basic categories: renewable and nonrenewable. Consider the bar graph of resource usage. If we wanted to reduce the use of nonrenewable natural resources, it would be least important to A) reduce deforestation.
#5. Nicolaus Copernicus was a Polish astronomer who is best known for the theory that the sun is near the center of the universe and that the earth and other planets revolve around it. Copernicus did not believe that the planets were influenced by or revolved due to the sun; instead he believed that the sun was located near the center of the universe and that it was this center which influenced those bodies and caused them to revolve. When this theory was first published, the scientific community did not accept it. Which reason BEST explains the reason for rejection of this theory?
C) It lacked sufficient evidence and explanation.

Answer: The correct answer to the question is option WHEN GLUCOSE LEVELS ARE LOW AND LACTOSE IS PRESENT.
Explanation: To start with,Lac operon can be simply defined as a part of the DNA that is under the part of the DNA is manipulated and controlled by the same promoter,they can be found in some prokaryotic cells giving room for regulation over excess synthesis of protein.so simply put,these specific segment of the DNA binds with the segment of the polymerase of RNA so that transcription of the mRNA from the operon genes will be achieved.
Lac operon is also known as lactose operon, it is seen in some enteric bacteria like e.coli where they play a crucial role in coding of genes for those proteins that function in moving lactose into the cystocel and digesting it to form glucose that is used for energy generation. These lac operon are are most active when glucose levels are low and lactose is present,with the low level of glucose, the lac operon can be transcribed to a high level,this is to ascertain that the bacteria only gets to activate the lac operon and can only make use of it,that is using lactose when all the preferred energy source from glucose has been exhausted.
