As discussed in

Protein systhesis in Eukaryotic cells -

Takes place in cytoplasm, mitochondria and plastids

-

 

 Protein synthesis takes place in mitochondria, hence option (b) is not correct.

Mitochondria and chloroplast both contain DNA and are self-replicating, hence semi-autonomous.


Option 1)

Both (a) and (b) are correct.

this is the incorrect option

Option 2)

(b) is true but (a) is false.

this is the incorrect option

Option 3)

(a) is true but (b) is false.

this is the correct option

Option 4)

Both (a) and (b) are false.

this is the incorrect option
