Q. Statement I : Split genes are found in eukaryotes.
Statement II : Introns or intervening sequences are found in eukaryotes.

Molecular Basis of Inheritance

Solution:

• In eukaryotes, the monocistronic structural genes have interrupted coding sequences - the genes in eukaryotes are split.
• The coding sequences or expressed sequences are defined as exons.
• Exons are said to be those sequence that appear in mature or processed RNA.
• The exons are interrupted by introns.
• Introns or intervening sequences do not appear in mature or processed RNA.
