Gselect all the true statements describing the oxidation of odd- and even‑chain fatty acid oxidation. oxidation of an odd‑chain fatty acid produces multiple acetyl groups and one propionyl group attached to coa molecules. only even‑chain fatty acids are oxidized to produce acetyl groups bound to coa molecules. only odd‑chain fatty acids are oxidized to produce propionyl groups bound to coa molecules. oxidation of an odd‑chain fatty acid produces multiple propionyl groups bound to coa molecules. oxidation of an even‑chain fatty acid produces multiple acetyl groups bound to coa molecules.

Here are the true statements

I) Oxidation of an odd‑chain fatty acid produces multiple acetyl groups and one propionyl group attached to CoA molecules.

II) Oxidation of an even‑chain fatty acid produces multiple acetyl groups bound to CoA molecules.

Explanation:

Oxidation of fatty acids is the breaking down a fatty acid into units of acetyl-CoA. It occurs in the mitochondria, and usually in the presence of oxygen.

Even-chain fatty acids have even number of carbon atoms e.g palmitic acid (16C) stearic acid (18C) etc. Their oxidation yields only acetyl-CoA units.

Odd-chain fatty acids possess odd number of carbon atoms e.g heptadecanoic acid (17C). Their oxidation yields acetyl-CoA units and a propionyl Co-A unit

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
