Document Summary
Gene segments of dna; located on chromosomes; unit of inheritance; give rise to a functional product. Pyrimidines nitrogenous bases characterized by a six membered ring made up of carbon and nitrogen atoms. Purine nitrogenous bases characterized by a five membered ring fused to a six membered ring where both rings are made up of carbon and nitrogen atoms. Transformation the assimilation of external genetic material by a cell. Hydrogen bonds double strand of dna; form between nitrogen bases of strands. Covalent bonds single strand of dna; unequal distribution. Replication bubble section of separated and unwound dna. Replication fork junction between separated strands and intact helix: chargraffs rule be able to work problems associated with this rule. Nucleotides orient in same direction; 3" end = free sugar end; 5" = free phosphate end; 3"end of one strand aligns with 5" end of another strand. Guanine and adenine are purine; thymine and cytosine are pyrimidine: griffiths experiments.
