What is not a function of these RNA processing steps? - correct answer--a. 5' 7-methyl guanosine cap facilitates attachment of ribosomes b. 3' polyA tail addition enhances transcription c. Protect the mRNA from degradation by ribonucleases d. Contribute to the stability of the mRNAs What does not promote the initiation of DNA replication in bacteria? - correct ...
