It is believed that mitchondrial DNA (mtDNA) follows a non-Mendelian inheritance pattern. It is hypothesized that all mitochondria are inherited from the egg, and the sperm cell does not contribute mitochondria to the fertilized egg.
Which of the following experimental procedures would be the best method to test this theory?
Test the mtDNA of random flies to determine if all flies have the same mtDNA
Mate a specific fly, and test the mtDNA of both a male and female offspring to see if the mtDNA is identical to the
mother.
Mate a specific female fly, and select a male and female offspring. Mate them with each other and test the mtDNA of
the "grandchildren."
O Mate a female fly, and mate the offspring with unrelated flies with different mtDNA. Test the mtDNA of the
"grandchildren."

it would lead to upper respiratory infections and pneumonia.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
