The processes of transcription and translation are critical pieces of gene expression to produce proteins in all living cells on earth. In eukaryotes, following transcription, the mRNA must be modified before translation can occur. Which of these processes likely
describes how mRNA is modified before it leaves the nucleus to be translated? You may select more than one choice.
A) A 5' cap is placed on one end of the mRNA molecule.
B) A poly-A tail is placed on one end of the molecule.
C) Non-coding intron region are removed from the mRNA molecule.
D) The uracil nitrogenous bases are replaced with thymine nitrogenous bases.
E) The mRNA is converted to a double stranded molecule following the base
pair rules
