The DNA present in the chloroplast (cpDNA) is a circular genome.
Chloroplast DNA (cpDNA) Details
Here's a breakdown of key characteristics of cpDNA based on the provided reference:
-
Structure: Circular genome.
-
Size: Varies from approximately 120,000 to 247,000 nucleotides in photosynthetic land plants. This size variation is largely due to a large inverted repeat that includes genes for the rRNA subunits.
-
Number of Copies: Each chloroplast contains roughly 22 to 900 cpDNA copies.
-
Gene Encoding: Encodes approximately 123 genes.
