Genes in Eukaryotic Cells Often Have Intronic Sequences Coded for Within

question 5

Multiple Choice

Genes in eukaryotic cells often have intronic sequences coded for within the DNA.These sequences are ultimately not translated into proteins.Why?

• A)Intronic sequences are removed from RNA molecules by the spliceosome, which works in the nucleus.
• B)Introns are not transcribed by RNA polymerase.
• C)Introns are removed by catalytic RNAs in the cytoplasm.
• D)The ribosome will skip over intron sequences when translating RNA into protein.
