The introns of protein-encoding nuclear genes of higher eukaryotes almost invariably begin (5') with GT and end (3') with AG. In addition, the 3'subterminal A in the “TACTAAC box” is completely conserved; this A is involved in bond formation during intron excision.
B is the correct answer
A prokaryote cell has no distinct nucleus with a membrane and neither does it have other specialized organelle.
In a eukaryotic cell, the genetic material is DNA in the form of chromosomes which are found within a distinct nucleus.
Examples of prokaryotes Streptomyces soil bacteria (from which streptomycin antibiotic is derived), Escherichia coli bacterium and Streptococcus bacteria (which causes strep sore throat).
Examples of Eukaryotes include protozoa such as amoeba, fungi, plants, animals and generally all multicellular organisms.
