Gene Type Description A. Monocistronic Gene 1. Gene arrangement found mostly in bacteria or prokaryotes where one mRNA molecule codes for multiple polypeptides. B. Polycistronic Gene 2. Gene arrangement found mostly in eukaryotes where one mRNA molecule codes for a single polypeptide. C. Exon 3. Coding sequences in a gene that are expressed in the mature RNA. D. Intron 4. Non-coding sequences in a gene that are remov

Options

  1. AA - 2, B - 1, C - 3, D - 4
  2. BA - 1, B - 2, C - 4, D - 3
  3. CA - 2, B - 1, C - 4, D - 3
  4. DA - 1, B - 2, C - 4, D - 3

Correct answer

A. A - 2, B - 1, C - 3, D - 4

Step-by-step solution

A - 2: Monocistronic genes are found mostly in eukaryotes where one mRNA molecule codes for a single polypeptide. B - 1: Polycistronic genes are found mostly in bacteria or prokaryotes where one mRNA molecule codes for multiple polypeptides. C - 3: Exons are coding sequences that appear in the mature or processed RNA. D - 4: Introns are non-coding sequences that are removed from the mature RNA.
