Which of the following properties of transposable elements allows them to contribute to the C-value paradox?
il63 [147K]

Answer:

All of these choices are correct.

Explanation:

Transposable elements or jumping genes has the ability to move from one site to another in the genome of an organism. The C value paradox indicates that the complexity of an organism doe not depend on the amount of the haploid content of DNA.

Transposable elements also correspond to the C value paradox. Their complexity can not be contributed by their amount of DNA. Their copy number can present on multiple chromosomes and their replication is controlled by the gene present on transposable element. The copy number of transposable element can increase in the next generation by copy and paste mechanism.

Thus, the correct answer is option (d).

The concentration of H⁺ ions inside the mitochondrial matrix is lower than it is in the cytosol or the mitochondrial intermembra
nikdorinn [45]

Answer:

(b) inhibition of ATP synthesis

Explanation:

The inner mitochondrial membrane is impermeable to protons. Electron transfer from NADH and FADH2 to molecular oxygen via electron transport chain generates electrochemical gradient by pumping the protons from matrix to intermembrane space. This electrochemical gradient drives ATP synthesis by down the concentration gradient transport of protons back to the matrix via proton channels.

A compound able to carry protons back to the mitochondrial matrix would dissipate the electrochemical gradient. In the absence of proton concentration gradient across the inner mitochondrial membrane, ATP synthesis would stop.
