In E.coli,the genetic material is composed of _________. A)RNA and protein B)circular,double- stranded DNA C)circular,double- stranded RNA D)polypeptide chains E)linear,double- stranded DNA

Question

Quizplus · Accepted Answer

E.coli has a circular, double-stranded DNA as its genetic material. RNA and protein are involved in gene expression, but they are not the main components of the genetic material. Circular, double-stranded RNA is rare in cells and is usually found in viruses. Polypeptide chains are involved in protein synthesis, but they are not the genetic material. Linear, double-stranded DNA is found in eukaryotic cells, but not in bacteria like E.coli.
