2. Thymine with Adenine & Cytosine with Guanine
3. The Dna double helix must unwind near the gene which is supposed to get transcribed.
4. RNA polymerase
5. Uracil with Adenine & Cytosine with Guanine
8. Nucleotides
9. RNA polymerase
10. Dna - 2 strands MRNA - 4 strands
11. MRNA is an intermediary between the genetic info in Dna and the sequence of amino acids in proteins
These proteins allow substances to enter that wouldn't be able to otherwise. Only small hydrophobic substances can enter cells. However, these proteins aid crucial substsances in entering the cell.<span />
