Question
Why do prokaryotes only have a single chromosome?
Open in App
Solution
Prokaryotes:
Prokaryotes are unicellular organisms that are devoid of a nucleus and membrane-bound organelles.
The prokaryotic cytoplasm carries the genetic material in the form of DNA which is usually round in shape.
They also carry additional DNA content as plasmids that encode proteins which aid in their survival in host systems.
Chromosomes are proteins present in the nucleus that delivers genetic information to the offsprings.
Prokaryotes possess only a single chromosome due to their simple body design.
The single chromosome allows them to carry only a few genes which can be accommodated within a single chromosomal strand.
