Question

Matrix of Mitochondria contains
(A) Single circular DNA molecule, few RNA molecules, 80s type of ribosomes
) ,
(B) Single circular DNA molecule, few RNA molecules, 70s type ribosomes
(C) Single circular DNA molecule, 80s ribosomes
(D) Single circular DNA molecule, 70s ribosomes only​

Answer 1

Answer:

Mitochondria are semi-autonomous organelles. However, mitochondria are not fully autonomous because their structure and functioning are partially controlled by the nucleus of the cell and the availability of materials from the cytoplasm. So, it is more appropriate to call them semi-autonomous organelles. Semi-autonomy of mitochondria is because they have their own DNA which can replicate independently. Mitochondrial matrix possesses its own ribosomes (the 70S in nature). It synthesizes some of its own structural proteins. New mitochondria, developed by the division of pre-existing mitochondria.

So, the correct answer is '(i), (ii) and (iii)'.
