The DNA present in chloroplast is:
Both Chloroplast and Mitochondria DNA are CIRCULAR and DOUBLE-STRANDED (dsDNA), reflecting their endosymbiotic prokaryotic origin!
The stroma of the chloroplast contains enzymes required for the synthesis of carbohydrates and proteins. It also contains small, double-stranded circular DNA molecules and ribosomes.
Plastids and mitochondria evolved from endosymbiotic prokaryotes. As in bacteria, their genetic material consists of closed circular double-stranded DNA (dsDNA), distinct from the linear chromatin of the eukaryotic nucleus.
Chloroplast DNA is circular and double stranded, matching Option (4).
Diagnose every choice: Know exactly why the right option works and why distractors fail.
Chloroplast DNA is double-stranded and circular, not single-stranded linear.
Plastid genomes are double-stranded duplexes.
Nuclear chromosomes are linear double-stranded DNA; organellar genomes are circular.
Chloroplasts possess small, circular, double-stranded DNA molecules in their stroma.
Assuming eukaryotic cells have only linear double-stranded DNA throughout.
"The stroma of the chloroplast contains enzymes required for the synthesis of carbohydrates and proteins. It also contains small, double-stranded circular DNA molecules and ribosomes."
