Lesson: DNA in Prokaryotes Biology • Third Year of Secondary School

Join Nagwa Classes

Attend live Biology sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to describe the structures that contain DNA within prokaryotic cells.

Students will be able to

recall that DNA is contained in prokaryotes in the form of a chromosomal loop and plasmids,
describe the structure of plasmids and a chromosomal loop,
compare the arrangement of DNA in prokaryotic cells with that of eukaryotic cells,
use knowledge of prokaryotic DNA to suggest ideas about the evolution of chloroplast and mitochondria.
