Document Summary

Dna molecule controls cell structure and function, it actually does nothing it just sits there and house the genetic info. It passes gene info on to the next generation. It governs how genetic info is used, or expressed in a cell. Dna is a polymer composed of monomer subunits nucleotides. Nucleotides are linked together into a linear sequence. Two strands form double helix thru hydrogen bonds. The double helix twist itself and form a more complex 3d structure. Phosphate molecule(s) are attached to the 5" carbon. Hydroxyl group is attached to the 3" carbon. Base (a/t/g/c) is attached to the 1" carbon. Two strands are complementary and antiparallel to each other: Enzymes use dna as template for replication and transcription. Gene regulatory proteins determines the time of reactions. Acetylases, methylated and other enzymes that modify the dna. Dna is a blueprint that determines the rna sequence, where rna determines the amino acid sequence in polypeptide.
