This lesson will discuss how scientists use dominant and recessive genes to predict inherited traits of offspring.
Khan Academy
Khan Academy: Antiparallel Structure of Dna Strands
DNA is composed of two strands of nucleotides held together by hydrogen bonding. The strands each run from 5' to 3' and run in antiparallel, or opposite, directions from one another. [9:57]
