Ribosomes don't contain DNA. It is the site of production of proteins. It also have mRNA, rRNA and tRNA and also other enzymes, which play significant role in protein syntheis. It consists of
60% - 65% - RNA
30% - 35% - Proteins
Whereas, DNA is present in its store house, i.e., nucleus and some DNA is also present in mitochondria and chloroplast.
Nuclear envelope is derivative of
smooth endoplasmic reticulum

The figure below shows the structure of a mitochondrion with its four parts labelled (A), (B), (C) and (D). Select the part correctly matched with its function
D - outer membrane -gives - rise to inner membrane by splitting
B - Inner membrane - forms infolding called cristae
C - Cristae - possess single circular DNA molecule and ribosomes
