Which of the following describes the process of alternative RNA splicing?

• Different mRNA molecules are made from different sections of DNA

• Different mRNA molecules are made from cutting out different exons from same pre-mRNA

• Different mRNA molecules are absorbed from the environment for recombination

• Different mRNA molecules are absorbed from the mitochondria for translation

Which of the following is the function of the poly-A tail?

Which of the following describes the difference between a prokaryote mRNA and eukaryote mRNA?
