Question

multiple choice question
the bacterial nucleoid is composed of ______.

only dna
protein and rna
protein and dna
an aggregate of vesicles

Explanation:

The bacterial nucleoid is the region that contains the bacterial chromosome. It is composed of protein (like nucleoid - associated proteins that help in organizing the DNA) and DNA. "Only DNA" is incorrect as proteins are also present. "Protein and RNA" is wrong as the main nucleic acid here is DNA. "An aggregate of vesicles" is not related to nucleoid composition.

Answer:

C. protein and DNA
