Answer:
You can use an iodine solution to detect the presence of complex carbohydrates.
Explanation:
The yellow-orange iodine will turn blue-black as it reacts with starch. (The iodine solution will show no reaction with simple carbohydrates or sugars.)
Answer:
The answer is D) Another biopsy from a distinct site may show a different result.
Explanation:
In molecular biology southern blot is used to detect a specific sequence of DNA. Mitochondria are energy producing organelles in the cell and they possess DNA that is inherited only from the mother. Although Southern blot is the classic method used to detect large deletions in mitochondrial DNA, it is not always sensitive enough to detect heteroplasmic deletions at low levels leading to results that are not always reliable. Heteroplasmy refers to the presence of more than one mitochondrial DNA in an individual. The presence of a mutation in the mitochondrial DNA can create an intracellular heteroplasmic mix of mutant and normal mitochondrial DNA. Cells with a higher rate of cell division like blood can yield inconclusive results in southern analysis because heteroplasmy favors wild type mitochondrial DNA. Thus, non-dividing cells such as muscle cells are preferred for the analysis.
Water vapor in the atmosphere is the source of water cycle.
