In eukaryotes, extranuclear inheritance occurs when genetic information is transmitted by mechanisms other than through nuclear
DNA. Chloroplast DNA (cpDNA) is an example of one mechanism by which extranuclear inheritance can occur. Select the statements that correctly describe cpDNA.1. cpDNA organization is more similar to that of prokaryotes than eukaryotes.2. Chloroplast chromosome size and gene content are identical in all organisms.3. Chloroplast chromosomes contain genes that are involved in photophosphorylation.4. cpDNA is typically inherited from both parents.
It is given that the number of chromosomes present in each onion root tip cell is 16. Hence, the number of chromosomes in the cell will be 16 at G1 phase, after S phase and after M phase
