Answer:
If the lac enzyme continues to be produced even in the absence of lactose, the cell will be expending energy unnecessarily and this will be a problem for the supply of energy for other metabolic processes.
If the lac operator gene is dragged to any stretch of DNA, that gene may provide an inadequate reading generating a mutation.
Explanation:
The lac operon is an essential molecule for the transport and metabolism of lactose in microorganisms. This molecule has a fundamental function in the life of these single-celled organisms and must be synthesized immediately when lactose is present in the organism, however, its synthesis must be stopped as soon as the lactose is metabolized, otherwise the cell can spend energy unnecessarily preventing others Metabolic processes take place, which is a big problem if you only have one cell.
In addition, if for some reason, the lac operon gene is dragged on the DNA strand, an incorrect reading of the DNA bases can occur, which can cause mutations.
Three questions that focuses on the cause and effect relationship between the genetic code and gene expression, mechanisms of gene regulation and/or the role of DNA segments that is not involved in coding the proteins are:
i. Illustrate the process of translation and explain it with the help of a diagram.
ii. What are codons? Name the stop codons in eukaryotes.
iii. What are exons and introns? Explain what happens to the introns during the process of transcription and translation?
Answer:
Positive charge. They are the opposite of electrons.
The Nucleus is sort of like the "brain" of a cell.
B - energy flow from one tropic level to the next
