1) RNA polymerase finds the promoter sequence on DNA.
2)RNA polymerase reads the DNA and builds complementary sequence.
3) Intron séquences are spliced out and exons are joined together.
4) The ends of the mature transcript are protected before it leaves the nucleus.
5) The mRNA attachés to the ribosome.
6) transfer RNA arrives at the ribosome and the anticodon complements to the mRNA codon.
7)amino acids form peptide bonds as tRNA molecules match the mRNA.

The correct answer for the question "A student looks at a slice of tissue on an unlabelled microscope slide. the student concludes that the tissue is not from an animal because the cells in t<span>he tissue have" is D. Cell walls. When we compare animal and plant cells, only plant cells have cell walls. Cell walls are formed because of cellulose. </span>
