Answer:
Option (1), (2) and (3).
Explanation:
DNA is the genetic material of all the living organisms present on earth. The DNA contains the nitrogenous bases, pentose sugar and the phosphate group. DNA strands runs in the opposite direction and shows polarity.
Watson and Crick explain the structure of DNA based on the X ray diffraction produced by Rosalind. According to the structure, chromosomes are present in the nucleus and contains the DNA and wrapped around the proteins. The genes is considered as the functional segment of DNA.
Thus, the correct answer is option (1), (2) and (3).
The following are the statements that accurately demonstrate the electron transport chain:
1. The electron transfer in the electron transport chain is combined with the proton transfer from the matrix to the intermembrane space.
2. The prosthetic groups, like Fe-S centers, directly take part in the transfer of electrons.
3. The electron carriers in the electron transport chain comprise cytochrome C and ubiquinone (coenzyme Q).
4. The electron carriers are arranged into four complexes of prosthetic groups and proteins.
5. The reactions of the electron transport chain occur in the inner membrane of mitochondria.
