Which suspect’s DNA matches that found at the crime scene? Does this automatically mean that the suspect is guilty? 2. What poss
igomit [66]

Answer:

RFLP analysis of genomic DNA is facilitated by Southern blot analysis.   After electro-phoresis, DNA fragments in the gel are denatured by soaking in an alkali solution.  This causes double-stranded fragments to be converted into single-stranded form (no longer base-paired in a double helix).  A replica of the electrophoretic pattern of DNA fragments in the gel is made by transferring (blotting) them to a sheet of nitrocellulose or nylon membrane. This is done by placing the membrane on the gel after electro-phoresis and transferring DNA fragments to the membrane by capillary action or electro-transfer.  DNA, which is not visible, becomes permanently adsorbed to the membrane, that can then be manipulated easier than gels.

Which molecule from glycolysis or the citric acid pathway serves as the building block for lipid synthesis?
Mariana [72]

Answer: Acetyl-CoA

Explanation:

Acetyl-CoA can be obtained from the pyruvate, the end product of aerobic glycolysis. Also, Acetyl-CoA is the one of the starting materials of citric acid cycle.

For lipid synthesis, biotin carries activated CO2 that is incorporated into acetyl-CoA to form Malonyl-CoA, which is then elongated to yield various lipids of different length.

Thus, Acetyl-CoA is the building block of lipid synthesis
