Chloroplast DNA is circular.
Chloroplast DNA Details
Chloroplast DNA (cpDNA) is found within chloroplasts, the organelles responsible for photosynthesis in plants and algae. It is distinct from the nuclear DNA of the cell.
Key Characteristics:
- Shape: As stated, cpDNA is circular.
- Size: Typically ranges from 120,000 to 170,000 base pairs long.
- Contour Length: Has a contour length of around 30–60 micrometers.
- Mass: Has a mass of about 80–130 million daltons.
In essence, chloroplast DNA exists as a circular molecule within the chloroplast, playing a vital role in the organelle's function.
