Molecule 1 represents DNA and molecule 2 represents mRNA.
An mRNA molecule is made (thanks to RNA polymerase) according to the complementary code (with the exception that U replaces the T) of the transcribed DNA strand (template or antisense strand).
Plants and animals are living things. They feed, respire, excrete, grow, move, reproduce and are sensitive to their environment. Animals and plants need food for energy but they feed in different ways.
