The eukaryotic genome differs from the prokaryotic genome because
DNA is complexed with histones in prokaryotes
Repetitive sequences are present in eukaryotes
Genes in the former cases are organized into operons
DNA is circular and single stranded in prokaryotes
Cell recognition and adhesion occur due to biochemicals of cell membranes named
Proteins
Lipids
Proteins and Lipids

Number of chromatids at metaphase is
Two each in mitosis and meiosis
Two in mitosis and one in meiosis
Two in mitosis and four in meiosis
One in mitosis and two in meiosis
