NEET Solved Paper 2016 Question 11
Question: Mitochondria and chloroplast are:
(i) Semi - autonomous organelles (ii) Formed by division of pre - existing organelles and they contain DNA but lack protein synthesizing machinery Which one of the following options is correct?
Options:
A) Both (i) and (ii) are correct
B) (ii) is true but (i) is false
C) (i) is true but (ii) is false
D) Both (i) and (ii) are false
Show Answer
Answer:
Correct Answer: C
Solution:
- Mitochondria and chloroplasts are indeed semi-autonomous organelles (i), meaning they have their own DNA and can replicate independently of the cell’s nucleus. However, while they do contain their own DNA, they also have the machinery necessary for protein synthesis, including ribosomes (ii). Therefore, statement (ii) is false because it incorrectly states that they lack protein synthesizing machinery.
