Final answer:
Gram-positive bacteria are classified into high G+C and low G+C groups. High G+C bacteria belong to the class Actinobacteria and have more than 50% guanine and cytosine nucleotides. Low G+C bacteria belong to the class Bacilli and have less than 50% guanine and cytosine nucleotides.
Step-by-step explanation:
Gram-positive bacteria are classified into high G+C gram-positive and low G+C gram-positive bacteria. The high G+C gram-positive bacteria belong to the class Actinobacteria and have more than 50% guanine and cytosine nucleotides in their DNA. Examples of high G+C gram-positive bacteria include Actinomyces, Corynebacterium, Micrococcus, and Mycobacterium.
Low G+C gram-positive bacteria belong to the class Bacilli and have less than 50% guanine and cytosine nucleotides in their DNA. Examples of low G+C gram-positive bacteria include Bacillus, Clostridium, Lactobacillus, and Staphylococcus.
