Answer:
The CRA-cAMP complex increases the rate of expression of lac operon when glucose is absent and lactose is present as nutrient.
Explanation:
CRP is the catabolite gene activator protein that forms a complex with cAMP. The CRP-cAMP complex facilitates the binding of RNA polymerase to the promoter region of the lac operon. This robust binding as stimulated by CRP-cAMP complex is followed by the formation of open complex and initiation of gene expression.
Hence, the CRP-cAMP complex positively regulates the lac operon and increases its expression when glucose is not present.
Eating a diet high in sugar can lead to a condition called diabetes.
Hope this helps.
One example of a long term effect such as loss of habitat could be a possible decrease in population of a species and others that rely on it.
<span>Here square frequency of recessive alleles r^2 = 160/1000 = 0.16
Therefore r = 0.16
Since r + d = 1; d = 1-0.16 = 0.84</span>
Escherichia coli (E. coli) bacteria normally live in the intestines of people and animals. Most E. coli are harmless and actually are an important part of a healthy human intestinal tract.
