[6] Nucleoids Chloroplast DNA contains genes that are involved with aspects of photosynthesis and other chloroplast activities. It is thought that both chloroplasts and mitochondria are descended from free-living cyanobacteria, which could explain why they possess DNA that is distinct from the rest of the cell. 2020-09-30 Chloroplast has its own DNA and can reproduce independently, from the rest of the cell. They also produce amino acids and lipids required for the production of chloroplast membrane. Also Read: Plastids 2012-08-30 Morphological observations have been made on spinach chloroplast DNA transcription.
Importantly, the DNA in mitochondria and chloroplasts is not the same as the DNA in the nucleus, and the DNA in the mitochondria and chloroplasts is circular in shape, which is also the shape of DNA in prokaryotes (single-celled organisms without a nucleus). Each chloroplast with several nucleoid regions containing 8-10 rings of DNA molecules. The number of DNA copies in mature chloroplast is 15-20. 4. Chloroplast genome include ~100 genes, 46-90 protein coding genes, Code for 4 ribosomal RNAs, 21 ribosomal proteins, 4 RNA polymerase subunits and over 30 tRNA genes.
cpDNA and plastome are synonyms for chloroplast DNA. cpDNA is double-stranded circular DNA. Figure 02: Chloroplast DNA Though cpDNA occurs as a single chromosome, it exists as multiple copies.

Cells transferred from a nutrient-enriched medium to an inorganic medium in the light showed a drop in cell division rate, a reduction in chloroplast DNA content, and changes in the shape of chloroplast nucleoids as cells divided. We then examined DNA synthesis by immunodetecting BrdU incorporated into DNA strands using the anti-BrdU antibody.

Chloroplasts are the same size as prokaryotic cells, divide by binary fission, and, like bacteria, have Fts (Filamenting temperature sensitive) proteins at their division plane. Chloroplasts have their own DNA that is circular, not linear.
