- A principle function of 5' and 3' end modifications of eukaryotic mRNA is: a. to ensure that all nucleotides are phosphorylated b. to protect RNA from nucleolytic degradation c. to guide the removal of introns d. to serve as binding sites for translation release factorsarrow_forwardConsider this list (below) of steps involved in transcription. These steps are out of order. TRANSCRIPTION: 1. mRNA travels through a nuclear pore and enters the cytoplasm 2. the mRNA polymerase attaches at the start of a specific gene 3. RNA polymerase reads the gene surface4. a transcription factor bonds to a promoter site5. DNA molecule is unwound 6. a complimentary mRNA is produced What is the correct order of this transcription?arrow_forward1. Transcription: a)State the role of RNA polymerase in gene transcription.b.
