RNA has Uracil instead of Thymine. All the other three bases also occurs in RNA, adenine, guanine and cytosine. Therefore a ATA DNA codon will be transcript to UAU by RNA. Both Thymine and Uracil have the same role in however have minor chemical differences.
MRNA has a complex secondary structure; 3D. While tRNA is more like an X figure.
She should ask how far apart are the contractions, has your water broken, etc
Answer:
A snap together model makes sense to use because to form compounds, atoms bond to each other. A plastic snap together toy demonstrates the bonds with the snaps, but can be disconnected and rearranged to model the formation of different compounds through chemical reactions.
