Question

Unlike bacterial transcripts, eukaryotic RNA transcripts are chemically modified because:

Chemical groups help protect the mRNAs from degradation in the eukaryotic cytoplasm, bacterial mRNAs are not degraded

Chemical groups facilitate the transport of eukaryotic RNAs from the nucleus to the cytoplasm, bacterial RNAs are synthesized in the cytoplasm

Eukaryotic RNA polymerases cannot transcribe genes unless they are chemically modified, bacterial RNA polymerases transcribe unmodified genes

Transcripts in eukaryotic cells contain non coding regions that must be removed, bacterial transcripts contain only coding sequence

b and d

a.)

Chemical groups help protect the mRNAs from degradation in the eukaryotic cytoplasm, bacterial mRNAs are not degraded
